The Layers of Your Skin
Your skin includes three layers known as epidermis, dermis, and fat.
Some health issues, such as dermatitis and infections, can affect how
these different layers work to protect your internal organs.
Your skin is your body’s largest external organ. It provides a barrier
between your body’s essential organs, muscles, tissues, and skeletal
system and the outside world. This barrier protects you from bacteria,
changing temperatures, and chemical exposure.
Your skin continuously communicates with your brain about what is
happening around you: touch, texture, temperature, tingling, pleasure,
and pain. Your skin, in cooperation with your nervous system, is the
primary organ for your sense of touch.
Your body couldn’t perform the functions that keep you alive without
the protection of your skin. And remember: no matter how
light or dark your skin is - it's ONLY THE TOP LAYER (epidermis) that
is that colour. ALL "blacks", for example, have "white" skin on
worn body parts (bottom of feet, inside of hands). It wears off
faster than it can be replaced.
Epidermis
The epidermis is the top layer of your skin. It’s the only layer that
is visible to the eyes. The epidermis is thicker than you might expect
and has five sublayers. The epidermis is composed of keratinized,
stratified squamous epithelium. It is made of four or five layers of
epithelial cells, depending on its location in the body. It does not
have any blood vessels within it (i.e., it is avascular). Skin that has
four layers of cells is referred to as “thin skin.” From deep to
superficial, these layers are the stratum basale**, stratum spinosum,
stratum granulosum, and stratum corneum. Most of the skin can be
classified as thin skin. “Thick skin” is found only on the palms of the
hands and the soles of the feet. It has a fifth layer, called the
stratum lucidum, located between the stratum corneum and the stratum
granulosum
Your epidermis is constantly shedding dead skin cells from the top
layer and replacing them with new healthy cells that grow in lower
layers. It is also home to your pores, which allow oil and sweat to
escape.
What is the layer of skin pigment ("race")?
The TOP
LAYER - no other layers of skin! As stated above, this is why black people have
"white" hands and feet. And although many brag about juvenile
things that actually ARE NOT differentiated by any "race", if they
only knew - it's the top layer of skin - not even 1mm thick!!
Also know: we are all the same "race" - the "human race".
All other differences are only melanin -
pigment - in a very thin, most
external layer. Yes - that is what all the wars and gangs are
about!! Maybe it's time to:
1) grow up!
2) educate ourselves
3) find out what are the "pros" -
and the "cons" of being
lighter/darker.
**
The stratum basale
Three cell types are in this layer: the basal cell, and two other cell
types are found dispersed among the basal cells in the stratum basale.
The first is a Merkel cell, which functions as a receptor and is
responsible for stimulating sensory nerves that the brain perceives as
touch. These cells are especially abundant on the surfaces of the hands
and feet. The second is a melanocyte, a cell that produces the pigment
melanin - which gives skin it's colour.
The color of skin is influenced by a number of pigments, including
melanin, carotene, and hemoglobin. Recall that melanin is produced by
cells called melanocytes, which are found scattered throughout the
stratum basale of the epidermis. The
melanin is
transferred into the
keratinocytes via a cellular vesicle called a melanosome (Figure 5.1.7).
This figure consists of two diagrams side by side. The right diagram
shows development of light colored skin; the left shows development of
dark-colored skin. In both, a brown melanocyte sits at the border
between the dermis and epidermis. The melanocyte has a large nucleus
and six finger-like extensions. These reach between cells of the
stratum basalis. Sections of the extensions detach and travel through
the skins. These are melanosomes. In the left diagram, both the
melanocyte and melanosomes contain melanin particles, shown as dark
dots. Melanosomes travel upwards to outer skin layers, releasing
melanin. As a result, keratinocytes in the left diagram contain several
melanin particles that darken skin color. In light colored skin, the
melanocyte contains no melanin. It still releases melanosomes into
upper layers of the skin; however, these melanosomes contain no
melanin. Therefore, the skin does not darken and remains light.
Figure 5.1.7 – Skin Pigmentation: The relative coloration of the skin
depends of the amount of melanin produced by melanocytes in the stratum
basale and taken up by keratinocytes.
Melanin occurs in two primary forms.
Eumelanin exists as very dark brown, and
brown - whereas pheomelanin provides a red color. Dark-skinned
individuals produce more melanin than those with pale skin. Exposure to
the UV rays of the sun or a tanning salon causes melanin to be
manufactured and built up in keratinocytes, as sun exposure stimulates
keratinocytes to secrete chemicals that stimulate melanocytes. The
accumulation of melanin in keratinocytes results in the darkening of
the skin, or a tan. This increased melanin accumulation protects the
DNA of epidermal cells from UV ray damage and the breakdown of folic
acid, a nutrient necessary for our health and well-being. In contrast,
too much melanin can interfere with the production of vitamin D, an
important nutrient involved in calcium absorption. There is a dynamic
interplay between the amount of protection from UV radiation that
melanin provides and the amount of vitamin D produced. The amount of
melanin produced, and therefore UV protection, is directly correlated
with the amount of sunlight exposure. The more sunlight, the more UV
protection, but the compromise is that with increased melanin there is
a decrease in vitamin D produced.
It requires about 10 days after initial sun exposure for melanin
synthesis to peak, which is why pale-skinned individuals tend to suffer
sunburns of the epidermis initially. Dark-skinned individuals can also
get sunburns, but are more protected than are pale-skinned individuals.
Melanosomes are temporary structures that are eventually destroyed by
fusion with lysosomes; this fact, along with melanin-filled
keratinocytes in the stratum corneum sloughing off, makes tanning
impermanent.
Too much sun exposure can eventually lead to wrinkling due to the
destruction of the cellular structure of the skin, and in severe cases,
can cause sufficient DNA damage to result in skin cancer.
Dermis
The dermis is thicker than the epidermis and contains all sweat and oil
glands, hair follicles, connective tissues, nerve endings, and lymph
vessels. While the epidermis covers your body in a visible layer, the
dermis is the layer of skin that really enables the function of
pathogen protection that your body needs.
Since the dermis contains collagen and elastin, it also helps support
the structure of skin that we see.
Subcutis
The layer of skin beneath the dermis is sometimes called the
subcutaneous fat, subcutis, or hypodermis layer. This layer provides
insulation for your body, keeping you warm. It also provides a cushion
that works like a shock absorber surrounding your vital organs.
There are plenty of blood vessels contained in the hypodermis. This is
the layer that attaches your skin to the muscles and tissue below it.
This layer can be thicker in some parts of your body than others and
tends to be determined by genetics.
Dark skin: pros and cons
All the positives first
The high
melanin concentration in the skin
cells
protects the skin against harmful UV rays and melanoma (skin cancer).
Reportedly,
skin cancer in black people is 25 times lesser compared to white
racial-ethnic groups.
The Stratum Corneum (the protective outer layer of
the skin which acts as a barrier between our skin and the outside
environment) of the black dark skin is very solid. It doesn’t allow
unwanted materials & bacteria to enter the skin & excessive
loss of water to exit from the skin which results in delayed wrinkles
and fine lines compared to fair-toned skin.
Well, that sounds very pleasant but let’s see the flip side of dark
skin too
All the negatives of dark skin tones!
Hyperpigmentation issues in darker tones are a big
common problem. Tyrosinase (the enzyme which handles the production of
Melanin) activity is more active in darker skin than Caucasian skin.
Because of this, any bumps in the skin like acne, cuts, or bites can
leave potential scarring or pigmentation.
Melasma, Vitiligo, Keloid, Pseudofolliculitis
barbae, and Dermatosis papulose nigra are all really annoying skin
conditions that mostly target black or dark skin types.

Skin color is the first thing you see when you see someone. Skin color
has many uses, and the color of one’s skin can give you a general idea
of the type of climate one’s ancestors evolved in. The lighter one’s
skin is may tell you that their ancestors evolved in low UVB radiation,
whereas the darker one’s skin is may tell you that their ancestors
evolved in high UVB places. So this tells us that as migration occurred
out of Africa, skin needed to lighten in order to synthesize vitamin D
in low UVB climes. Note that I won’t make any claims about any skin
color being an adaptation to any climate; I will just state that there
is a strong association between UVB and skin color—the higher the UVB
the darker the skin and the lower the UVB the lighter the skin.
The skin comprises about 16 percent of the human body, making it the
body’s largest organ. The outermost layer of skin—the
epidermis - is the point of contact with the environment. Then the
number of UVB rays in any given environment will
dictate the color of one’s skin - in an ancestral manner.
So the most important factor in skin color is melanin, which is
produced by melanocytes, but it accumulates in the keratinocytes of the
stratum basale (the deepest layer of the five layers of the epidermis)
and the stratum spinosum (the layer between the stratum granulosum and
the stratum basale). Two forms of melanin exist:
-
eumelanin (which is
dark brown) and
-
pheomelanin (which is reddish-yellow and contains
sulfur).
In his textbook Anatomy and Physiology: The Unity of Form and Function,
professor Ken Saladin writes:
People of different skin colors have essentially the
same number of melanocytes, but in dark-skinned people, the melanocytes
produce greater quantities of melanin, the melanin granules in the
keratanocytes are more spread out than tightly clumped, and the melanin
breaks down more slowly. Thus, melanized cells may be seen throughout
the epidermis, from stratum basale to stratum corneum. In light-skinned
people, the melanin is clumped near the keratinocyte nucleus, so it
imparts less color to the cells. It also breaks down more rapidly, so
little of it is seen beyond the stratum basale, if even there.
The amount of melanin in the skin also varies with
exposure to ultraviolet (UV) rays of sunlight, which stimulates melanin
synthesis and darken the skin. A sun-tan fades as melanin is degraded
in older keratinocytes and as the keratinocytes migrate to the surface
and exfoliate. (Saladin, 2010: 194)
Skin color is one of the most significant factors involved in
colonizing a certain, new, area where the skin color the group has is
not conducive to life in that clime. So, when the out of Africa
migration occurred, skin color needed to lighten as to better confer
survival in the new, colder climes. Though, there is an anomaly: Arctic
peoples. Why is their skin dark—at least relative to other peoples who
live or have lived in colder climates?
Think about life in the Arctic. It is pretty much all white. Food is
scarce, and they eat a lot of animal fat and protein. Now, think about
the ice. The ice reflects UV rays onto the skin of the Arctic people,
making it not as light as, say, Europeans and East Asians.
A term I’ve heard a lot over the years is “Black don’t crack”, speaking
to the fact that a lot of black people look young, even into old age.
What, if any, is the physiologic reason behind this?
We also know that skin color and UVB radiation are strongly related. We
know that there are numerous differences in skin biology when comparing
different peoples whose ancestors have evolved in different climates.
Are blacks more oily? [yes]
Darkly pigmented skin tends to have larger sebaceous glands. Sebaceous
glands are the tiny glands that blanket the scalp and skin to secrete a
thin layer of oil as lubrication. The larger the sebaceous gland, the
greater the oil production. As such, many people with darker skin have
oily skin. Unfortunately, oily skin is often acne-prone and acne-prone
dark skin may suffer from post-inflammatory hyperpigmentation (e.g.
those dark spots that form and remain at sites of inflammation,
typically after a pimple has cleared).
On a positive note, oily skin has a skin cell turnover rate that is 2.5
times faster than that of lighter skin. A faster skin cell turnover
rate helps reveal younger, healthier-looking skin. Moreover, darker
skin has a lower pH than lighter skin. A lower level of skin acidity
means that darker skin is highly antimicrobial and capable of
inhibiting bacterial, fungal and other parasitic infections of the skin.
To address the overproduction of oil, darker skinned individuals should
utilize products that are oil soluble.

Common Skin Conditions in Black Skin
Skin is so various when it comes to colors and types, from the dark brown to the pale ivory and so many shades in
between. Unfortunately, skin problems are typically all the same
therefore most skin conditions may happen in all races and all skin
types.
Nevertheless, some skin conditions seem to be more common to the dark
skin or to be more severe in the case of dark skin. Additionally, many
treatments for regular skin conditions may actually cause other
problems in the case of dark skin. In order to know how to take care of
your face and body, it’s fundamental that you get to know one or two
things about the biology of dark skin.
The basics on dark skin
The melanocytes refer to the color of all skin stems from cells and
they’re the one producing melanosomes as they’re all packed with the
natural chemical
melanin.
What we’ve learned from research so far is that all people have pretty
much the same number of melanocytes in skin tissues, no matter the
color of the skin. What separates us from each other is the size and
the distribution of the melanosomes. The larger and more they are, the
darker your skin is. You can navigate here for more about Lasting
Impression Medical Spa.
Melanin in the skin is responsible for absorbing and scattering energy
from the UV light, therefore a dark complexion is going to lower the
risk for sun damage, which is the main cause for skin aging and skin
cancer formation. Aging is a process that can be slowed down by a
healthy lifestyle, proper diet, and the proper skin products. There are
tons of products that can help in lessening the development of
pigmentation and wrinkles. The latest anti-aging ingredient is NMN
powder that can be found in so many of the best anti-aging products
like NMN bulk powder.
The chances for dark skin to develop pigmentation issues are quite high
and even a minor skin injury (a bug bite) may cause a slight change in
skin pigment, offering the dark spots (hyperpigmentation) the
opportunity to happen. Most girls freak out when they hear the words
Brazilian wax. This is mostly because it is associated with pain or
discomfort and because of the actual procedure itself, which kind of
exposes your most private parts to a complete stranger. Anyways, this
post is for those of you who haven’t got a Brazilian wax before, or who
don’t know what a Brazilian wax is. So, to keep it short and easy a
Brazilian wax is the process of waxing off all your pubic hair, back
and front. And by all I mean all. A Brazilian wax is different from a
bikini wax or a French wax which takes off only the sides around your
bikini line. Brazilian wax is a very good alternative to shaving.
Everybody hates shaving, especially in that area, so this is one good
reason. Another benefit is that it lasts a lot longer. This is because
the hair is removed from the follicle (or the root) instead of being
cut at the skin level. A Brazilian can last as long as 6 weeks, so
there you have it. You only need to take four or five of them during
the summer. You will get the best review of the what is a Brazilian wax
here.

The uniqueness of "black" skin
ONE of the most popular questions I get asked is, ‘Is skin not just
skin? Bar colour is it that different? Really? Really, really?’
Yes really, really. There are similarities, but "Black" skin is
physiologically different to white skin in a few ways. There are also
cultural differences in the way we treat the skin.
Melanin
Everyone – be you of "Black", "white" or mixed-race heritage – has
melanocyte cells, living in the very
bottom layer of your epidermis.
Within these melanocyte cells are the melanosomes granules which
contain the pigment called melanin. At this very early stage, the
granules are actually transparent with no colour at all. As they
migrate through the layers of skin, they then take on their distinctive
colour.
There are two different types of melanin pigment: eumelanin – a dark
brown pigment, and pheomelanin – a red or yellow tint. Black people and
those with darker skin tones have more eumelanin, hence our different
shades of brown skin colour.
The key factor when it comes to skin colour is the size and the amount
of melanocytes and melanosomes. Some studies have shown that Black skin
produces twice as much melanin as white skin. Together, with the more
even distribution of melanin in Black skin, it gives some protection
from premature ageing caused by UV radiation from the sun. On average,
research points to Black skin having an approximate natural sun
protection factor (SPF) of 13.4. White skin sits somewhere around 3.3.
But before you run amok with no sunscreen, remember that the increased
melanin levels in Black skin also make it more vulnerable to
discolouration, be it loss of colour (hypopigmentation) or
patchy,uneven deposits of colour (hyperpigmentation).
Water retention
Another point of difference between Black and white skin is the rate at
which water is lost through the skin. One of the functions of the skin
is to provide a barrier against water loss and to help the skin stay
hydrated. Anything that disrupts the skin’s delicate barrier can cause
increased water loss, which we in the business refer to as TEWL:
‘transepidermal water loss’. A significant number of studies show that
whilst Black skin has on average a higher sebum content and a more
compact stratum corneum than white skin, it also has lower ceramide
levels (fatty acids that waterproof the skin), so it is prone to
increased water loss. This contributes to increased dryness of the skin
and the increased likelihood of us experiencing dry, flaky and ashy
skin conditions. Ever get that dry, itchy feeling on your pins after
removing your tights? That is TEWL in action.
See MUCH more about melanin, Africa, and
SCIENCE below!
Scarring
They say too much of a good thing isn’t good for you, and that can be
the case with collagen. Black skin is more prone to what’s known as
‘hypertrophic’ and ‘keloid’ scarring, both caused by the overproduction
of collagen after injury.
A keloid scar forms when an injury penetrates the epidermis through to
the upper portion of the dermis, stimulating collagen production. If
the collagen doesn’t receive a signal to stop regenerating, it
continues to be produced at a higher rate and this accumulates as
keloid scar tissue into the surrounding skin. Some people can be so
prone that even a pimple can cause a keloid scar and they have to be
especially vigilant about treatments and products that work on the
basis of controlled injury (e.g.micro-needling) to the skin as it is
difficult to predict how their skin will react.
Differences in collagen
The statement ‘Black don’t crack’ is often used as a compliment because
Black women tend to have a later onset of fine lines and wrinkles
compared to white women of a comparable age. There is a reason for this
and it’s all to do with collagen and the effect of UVA rays on the skin.
Black skin has thicker, tighter, and smaller collagen fibres, formed
into bundles, and melanin acts like an overcoat protecting these
bundles from the damage that UV causes when it penetrates the skin. So
they stay intact for longer, firmly propping up skin. In comparison,
collagen in white skin is much more susceptible to UV damage due to the
lack of readily available protective melanin.
The collagen construction in white skin is under much more stress and
strain from extrinsic ageing factors because it is not as robust.
Whilst skin may be ‘just skin,’ understanding the differences between
Black and white skin is crucial in knowing how best to look after yours.
Everyone – be you of "Black", "white" or mixed-race heritage – has
melanocyte cells, living in the very
bottom layer of your epidermis.
Within these melanocyte cells are the melanosomes granules which
contain the pigment called melanin. At this very early stage, the
granules are actually transparent with no colour at all. As they
migrate through the layers of skin, they then take on their distinctive
colour.
Not to be confusid with "Melena"
- a form of blood in the stool which refers to the dark black, tarry
feces that are commonly associated with upper gastrointestinal bleeding. There are 5 basic types of melanin:
eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. Melanin is produced through a multistage chemical process known as melanogenesis, where the oxidation of the amino acid
tyrosine is followed by
polymerization.
Melanin is skin pigment. Now it is very common for "black" people
(there is no such thing as "black" melanin - like squirrels, rodents,
black bears .... it is DARK BROWN, never black) actually use methods
to _decrease_ melanin production or deposits in the skin,
such as laser therapy, ayurvedic or topical creams (which
bleach)! (Also, blue contact lenses, hair bleaching and
straightening)
Most people associate Africans with dark skin. But different groups of
people in Africa have almost every skin color on the planet, from
deepest black in the Dinka of South Sudan to beige in the San of South
Africa. Now, researchers have discovered a handful of new gene variants
responsible for this palette of tones.
The study, published online this week in Science, traces the evolution
of these genes and how they traveled around the world. While the dark
skin of some Pacific Islanders can be traced to Africa, gene variants
from Eurasia also seem to have made their way back to Africa. And
surprisingly, some of the mutations responsible for lighter skin in
Europeans turn out to have an ancient African origin.
“This is really a landmark study of skin color diversity,” says
geneticist Greg Barsh of the HudsonAlpha Institute for Biotechnology in
Huntsville, Alabama.

Researchers agree that our early australopithecine ancestors in Africa
probably had light skin beneath hairy pelts. “If you shave a
chimpanzee, its skin is light,” says evolutionary geneticist Sarah
Tishkoff of the University of Pennsylvania, the lead author of the new
study. “If you have body hair, you don’t need dark skin to protect you
from ultraviolet [UV] radiation.”
So, black people want to me "whiter", and white people want to be
black. Again, why don't people just accept themselves the way
they are????
For example, a “depigmentation gene” called SLC24A5 linked to pale skin
swept through European populations in the past 6000 years. But Tishkoff
’s team found that the story of skin color evolution isn’t so black and
white. Her team, including African researchers, used a light meter to
measure skin reflectance in 2092 people in Ethiopia, Tanzania, and
Botswana. They found the darkest skin in the Nilo-Saharan pastoralist
populations of eastern Africa, such as the Mursi and Surma, and the
lightest skin in the San of southern Africa, as well as many shades in
between, as in the Agaw people of Ethiopia.

At the same time, they collected blood samples for genetic studies.
They sequenced more than 4 million single nucleotide polymorphisms
(SNPs)—places where a single letter of the genetic code varies across
the genomes of 1570 of these Africans. They found four key areas of the
genome where specific SNPs correlate with skin color.
The first surprise was that SLC24A5, which swept Europe, is also common
in East Africa—found in as many as half the members of some Ethiopian
groups. This variant arose 30,000 years ago and was probably brought to
eastern Africa by people migrating from the Middle East, Tishkoff says.
But though many East Africans have this gene, they don’t have white
skin, probably because it is just one of several genes that shape their
skin color.
The team also found variants of two neighbouring genes, HERC2 and OCA2,
which are associated with light skin, eyes, and hair in Europeans but
arose in Africa; these variants are ancient and common in the
light-skinned San people. The team proposes that the variants arose in
Africa as early as 1 million years ago and spread later to Europeans
and Asians. “Many of the gene variants that cause light skin in Europe
have origins in Africa,” Tishkoff says.
The most dramatic discovery concerned a gene known as MFSD12. Two
mutations that decrease expression of this gene were found in high
frequencies in people with the darkest skin. These variants arose about
a half-million years ago, suggesting that human ancestors before that
time may have had moderately dark skin, rather than the deep black hue
created today by these mutations.
These same two variants are found in Melanesians, Australian
Aborigines, and some Indians. These people may have inherited the
variants from ancient migrants from Africa who followed a “southern
route” out of East Africa, along the southern coast of India to
Melanesia and Australia, Tishkoff says. That idea, however, counters
three genetic studies that concluded last year that Australians,
Melanesians, and Eurasians all descend from a single migration out of
Africa. Alternatively, this great migration may have included people
carrying variants for both light and dark skin, but the dark variants
later were lost in Eurasians.
To understand how the MFSD12 mutations help make darker skin, the
researchers reduced expression of the gene in cultured cells, mimicking
the action of the variants in dark-skinned people. The cells produced
more eumelanin, the pigment responsible for brown skin, hair,
and eyes. The mutations may also change skin color by blocking yellow
pigments: When the researchers knocked out MFSD12 in zebrafish and
mice, red and yellow pigments were lost, and the mice’s light brown
coats turned gray. “This new mechanism for producing intensely dark
pigmentation is really the big story,” says Nina Jablonski, an
anthropologist at Pennsylvania State University in State College.
The study adds to established research undercutting old notions of
race. You can’t use skin color to classify humans, any more than you
can use other complex traits like height, Tishkoff says. “There is so
much diversity in Africans that there is no such thing as an African
race.”

Why You Need to Reconsider That Sunscreen You’re Using
Even if you buy a European brand from an America drugstore, it might
not be as good as its international counterpart. National regulations
for ingredients and effectiveness vary across the globe, causing
products manufactured in other countries to be different, even if
they’re from the same brand.
While Congress enacted the Sunscreen Innovation Act in 2014 to
modernize and streamline sunscreen ingredient approval in the United
States, American products still seem to lag behind.
Sadly, this often means our sunscreens tend to be greasier, less
pleasant to put on and wear, and potentially less good at protecting
our skin and preventing signs of aging. So what’s the difference
between the sunscreen you buy in Tallahassee and the one you ordered
from Tokyo? Let’s take a closer look.
Other countries are way ahead in quality
There’s not a simple reason that places like England, France, Japan,
South Korea, and other countries have better sunblock products. It
comes down to a combination of three large factors.
1. American sunscreens work with fewer (and “older”)
ingredients
At the moment, the U. S. Food and Drug Administration (FDA) has only
approved 16 active ingredients for sunscreens. Europe has 27 approved
substances. Not only does this difference limit the range of products
in the United States, it can also impact effectiveness.
There are seven approved chemicals in Europe that protect against
cancer-causing UVA light rays. Meanwhile in the United States, we’ve
only got three approved chemicals for the same purpose.
Sunscreen manufacturers in the United States have limited ingredients
because we treat sunblocks as over-the-counter medical products. Every
active ingredient used in the United States must pass a rigorous
process through the FDA before we can use them, which is great for our
health, but also a reason things are moving so slowly.
Just look: The Sunscreen Innovation Act was enacted three years ago,
but no new ingredients have passed the medical trials since, according
to the FDA. Even when the research checks out, trials can also be
expensive. So if there’s no demand or financial benefit to developing
new products, there’s no incentive to create newer and better products.
On the other hand, other countries treat sunscreen products as
cosmetics. Although the ingredients go through different testing
processes, other countries’ regulations allow for faster approvals as
well as the ability for companies to combine ingredients without
restriction. As a result, these brands offer more options that don’t
just protect your skin, but they’re also much nicer to apply.
2. The FDA has lax regulations for UVA protection
Just when you thought the FDA was slow to introduce new ingredients,
they’re also not that strict about the amount of UVA protection
required. A recent study found that many of the American sunscreen
products labeled as “broad spectrum” block UVB rays but don’t block UVA
rays as effectively as European brands do. UVA penetrates the skin more
deeply than UVB.
In fact, the study, which comes from the Memorial Sloan Kettering
Cancer Center in New York, found that only 11 out of 20 American
sunscreen products met European standards of protection.
3. The culture of tanning in the United States
A third reason our sunblock might lag behind the rest of the world’s is
simply because Americans are still not as serious about sun protection
as other cultures are. Despite extensive findings that UV exposure
contributes to skin cancer, about 10 million American men and women
regularly use tanning beds. Tanning, in many ways, is part pastime,
part sign of luxury, and part identity.
Skin cancer: Get the facts
Even with evidence that sun exposure suppresses the immune system,
accelerates aging, and raises the risk of cancer, changing a culture
can be difficult. When consumers don’t demand something, it affects the
market and its interest in innovation. Here’s where Asian cultures,
such as in Japan, China, Korea, and the Philippines, differ. These
cultures are similarly enamored with pale skin, which contributes to
their wide range of high-quality sunscreen products. Because the market
is so competitive, the products are not only better, but cheaper as
well.
Ready to try a sunscreen from across the border?
You might initially be overwhelmed both by the choices and the language
barrier when you’re looking for sunscreens from other countries.
Luckily, online shops like Amazon stock many choices. As popularity
grows in the United States, it’s easier to find clear and helpful
reviews of the best products.
Here are three popular Japanese sunscreens, trialed and suggested:
Bioré Sarasara
Aqua Rich
Watery Essence
