The Skin: An Overview
The skin is the largest organ of immunity from disease and protects by:
• Keeping water and essential nutrients in and unwanted, toxic
• Regulating the temperature for warming and cooling. • Repairing damage from cuts, burns, environmental insults, or other The skin differs from organs like the heart or lungs because it constantly mends itself by replacing the outer layer daily. It is continually ready to respond to harm. Cuts close, producing new, pink skin. Sunburned skin becomes dry and peels, giving way to a pink, soft, smooth, and supple replacement layer. The environmental insults signal through the skin’s surface to layers below which begin the restoration process. The skin's outer layer is a "biological space suit" for life on earth much like space suits protecting astronauts from the hazardous conditions in outer space. Environmental insults include: • Sun. • Climatic changes: heat, cold, high or low humidity (moisture level in • Physical abuse: friction from chafing, rubbing, shaving. • Products that contact the skin like soaps, detergents, cleaning products, paint, grease, solvents, rubbing alcohol, and cosmetics. • Water (extended exposure to water damages the skin). • Lifestyle: smoking, drinking alcohol, lack of sleep.
These insults, including sun exposure, can suppress the immune
system which can result in skin cancer. Protection of the skin is,
therefore, critical for good health.
Skin Structure
The skin has three major layers: Epidermis, Dermis, Subcutaneous
tissue. The epidermis is the outermost layer and interacts directly with
the environment. The epidermis protects by providing a barrier to
outside materials (products, water, etc.) and by filtering sunlight. The
epidermis is self-renewing. The dermis is beneath the epidermis. It
contains the major structure-providing tissue fibers, collagen and
elastin. It also contains the vascular system to provide a blood supply
and nerve cells to process information to and from
the brain. The subcutaneous tissue contains the fat pad and muscle. The layers of the skin are shown in this diagram:
Like all tissues, the epidermis is made up of cells that have specific
functions in the skin. A cell called the keratinocyte makes up most of
the epidermis. The functions of the stratum corneum, the middle
epidermis, the basal layer, and the dermal-epidermal junction are
Stratum Corneum
The stratum corneum is the outermost layer, directly in contact with the
environment. It is about half the thickness of a piece of paper. On
average, the stratum corneum is about 20 cell layers thick. Despite its
thin dimensions, the stratum corneum is incredibly strong. The cells are
in a very well organized pattern. The stratum corneum has been
described as a "brick and mortar" structure, as shown:
The cells are the bricks and the lipids are the mortar. Lipids are "oily"
materials that do not easily mix with water, such as cooking oil,
petroleum jelly, baby oil, and grease. The skin lipids are mixtures of
materials that form a very well organized structure between the cells.
The lipid layer helps keep water in the stratum corneum by limiting
passage of water from beneath. The lipids also keep substances out of
the body. The stratum corneum contains water that is associated with
the protein materials in the cells. The cells hold onto water to keep
them flexible and to allow the body's movement without cracking the
upper layer.
Neighboring stratum corneum cells are joined together through small
attachments, called desmosomes, structures that are like small "rivets".
Each cell is attached at many points to nearby cells (cells above,
beneath, adjacent). These multiple attachments provide considerable
strength to this tissue. The very top layer of the stratum corneum
normally comes off or "sheds", about one cell layer per day. You can
observe this layer by placing a piece of clear tape and put it on the
back of your hand for a few minutes. Remove the tape and notice the
flaky material, which is the top layer of cells. The desmosomes need to
break in order to free the cells. This process, called desquamation, is
carefully programmed to occur at the proper time.

Middle Epidermis
Right below the bottom of the stratum corneum lies the middle
epidermis. At the top, the cells are flatter than the rest of the layer.
These top cells contain lipids and release them as they move upward.
These lipids then become the stratum corneum lipids. The remaining
cells are keratinocytes which have a cube shape and contain bundles
of filaments that help protect the skin from the friction during movement
and rubbing. Over time, the cells move upward to the top of the middle
epidermis and eventually become stratum corneum cells. Their
features change over time during this renewal and replacement
Basal Layer
The basal layer rests at the bottom of the middle epidermis. The basal
cells are different, however, because they actively divide to create new
basal cells. The older cells move up to form the middle epidermis. All
cells of the epidermis begin at this point by the process of cell division.
The cell division process needs protein and other nourishment that are
supplied by the functions of the dermis.
The basal layer contains a unique type of cell called the melanocyte or pigment cell. Unlike other basal cells, the melanocyte does not move upward. The melanocyte's job is to make a substance called pigment, or melanin, which contributes to the coloration of the skin. Melanocytes make melanin when ultraviolet radiation interacts with the
skin. The melanin is transferred from the melanocyte to the
keratinocytes of the middle epidermis, to protect the nuclei of these
cells from being damaged by radiation. Dark spots on the skin, such as
freckles, are clusters of epidermal keratinocytes with melanin
concentrated in them. Sun tanned skin has a more uniform distribution
of keratinocytes with melanin. Both conditions are the response of the
skin to sun exposure.
Dermal-Epidermal Junction
As the name suggests, the dermal-epidermal junction is right between
the epidermis and the dermis. This layer of the skin holds the epidermis
onto the dermis. It provides support to the entire tissue to help hold it in
Epidermal Cell Summary
The epidermis performs a wide variety of functions. Epidermal cells, or
keratinocytes, move from the basal cell layer to the top of the stratum
corneum in about 28 days. The specific time depends on the location
on the body, the overall state of health, and the type and severity of
environmental insult. The outermost layer of the stratum corneum
comes off each day. When injury to the skin occurs, again from some
sort of damage, the whole replenishment process works overtime to
restore the skin to its proper condition and to ensure a protective
barrier. In the case of serious injury, such as a major burn, the healing
process requires a long time. The melanocytes, or pigment cells,
housed in the bottom of the epidermis, produce melanin to protect the
epidermal cells from ultraviolet damage.
The epidermis is unusual in that it does not contain nerve endings. Yet,
the outer surface of the skin, the stratum corneum, can very easily
detect events, including changes in heat, cold and humidity. We can
also tell when the skin is touched. Even though it does not have nerve
endings, the epidermis is thought to play an important role in signaling
between the outside world and the brain.
The dermis is below the epidermis and above the subcutaneous tissue.

We can also tell when we touch the skin. Even though it does not have
nerve endings, the epidermis is thought to play an important role in
signaling between the outside world and the brain.
Collagen and elastin fibers make up a large part of the dermis. The
thick fibers of collagen support the skin. Elastin fibers are very flexible
and impart mechanical strength and resiliency to the skin by allowing it
to stretch. When the elastin is in good condition, the skin returns to its
original shape readily when it is flexed or stretched. If the elastin and
collagen are in poor condition, the skin lacks resiliency, sags, and
develops noticeable wrinkles.
The major functions of the dermis are to support the epidermis, to
provide bulk and to anchor the skin. Importantly, the dermis contains
blood vessels that bring oxygen and other nutrients to the basal layer
for the cell division process. Nerve endings are also found in the
dermis. Presumably they take signals from the epidermis, including the
stratum corneum, and transmit them to the brain. This signaling
function is unique because there are no nerve cells in the epidermis.
The diagram shows that the dermis has a compact array of fibrous
material, the collagen and elastin, necessary for support, resistance to
damage, and overall health.
Aging and Its Effects on the Skin
The effects of aging on the skin are currently of great interest. People
are living longer and more active lives than ever before. The "baby
boomers" are now in their 30s, 40s and 50s. They have large
disposable incomes and no intention of looking old. For them, "looking
good" and "feeling good" go together. The process of skin aging
process has two parts: natural aging, due to increasing chronological
age, and solar aging, due to the effects of the sun.
Natural Aging
Natural aging includes all of the environmental and genetic factors that
impact the skin, other than those due to solar damage. As the skin
ages, the cell movement from the bottom of the epidermis (basal layer)
to the top (outermost stratum corneum) becomes slower. The skin
surface becomes rougher, with a more uneven texture, because the
cells are shed more slowly. Often the slowed desquamation process
(remember the tape on your hand experiment?) results in the formation
of large
clumps of cells, observed as scales or dry skin flakes. The uneven
texture and scaling tend to make your skin look duller. The epidermis
becomes thinner and the skin becomes more fragile.
In the dermis, the elastic fibers become coarse and then disappear.
The coarseness makes them less elastic. The skin returns to its original
state much more slowly when it is stretched. The blood vessels
decrease in size and number. This change influences the nutrient
supply to the basal layer and accounts in part for the slower rate of
epidermal replenishment. Some of the factors in natural aging are
determined by the genetic make up of the individual. Much more needs
to be learned about specific genetic influences.
Photoaging & Sun Damage
Sunlight causes significant damage to the skin which, unfortunately,
does not show up right away. In fact, many people believe sun or
tanning bed exposure equals a healthy appearance and healthy skin.
This "socially desirable appearance" comes at the expense of poor
appearance and poor skin health as one gets older. Tanning beds
provide ultraviolet radiation through special bulbs and damage the skin
as much as the sun itself. Individuals who spend most of their time
indoors are still exposed to damaging rays when they do go outside.
Sun damage takes two forms, photoaging and skin cancer. The
majority of a lifetime sun exposure occurs before the age of 20.
Children receive three times more exposure to the sun than adults. The
damage process starts early in life unless the skin is protected. Many
non-melanoma skin cancers could be prevented with proper protection
from the sun.
Photoaging: The Epidermis
Ultraviolet radiation from the sun penetrates the stratum corneum. It
affects the epidermal cells and causes a change in thickness. Some
areas of the epidermis increase in size and others decrease to produce
an irregular, non-uniform structure. The normal, orderly processes of
the epidermis are disrupted. As a result, the epidermis cannot produce
a proper stratum corneum. The "defective" stratum corneum is irregular
and the very top layer does not slough off properly. Consequently, the
skin surface texture becomes rough and irregular. The skin
pigmentation, or coloration, becomes blotchy and irregular. This
happens because the melanocytes are forced, by the ultraviolet
radiation of the sun, to produce pigmentation. The pigment is
transferred to the keratinocytes of the middle epidermis and these
spots become visible when we view the skin surface. In
addition, the skin tone becomes sallow and appears to lack the vitality
of a healthy state.
Photoaging: The Dermis
Sunlight breaks down the collagen and elastin fibers in the dermis.
These structures become irregular. This irregularity in the dermal
support tissue leads to visible wrinkles. The fibers also lose their
elasticity, causing the skin to sag. Sun damage leads to chronic
inflammation of the dermis. As a consequence, the epidermis does not
function properly. The chronic inflammation causes the epidermis to
become thicker as it attempts to repair the damage.
Levels of Photoaging
Photoaging occurs to varying levels. In Level I, ultraviolet radiation
causes changes in the epidermis only. The alterations result in a dull,
rough outer layer and in pigmented spots. In Level II, changes are
caused in both the epidermis and the upper part of the dermis. Injury
from the sun leads to increased wrinkling, and alterations in
pigmentation and texture that are greater than those in Level I.
Consequently, the skin's features are not uniform, thereby exaggerating
the effects. In Level III, changes occur in the epidermis and throughout
the dermis. The wrinkling is more pronounced and the skin texture is
much less uniform, often pebbly in appearance. The skin takes on a
leathery appearance.
Skin Care
Skin care begins with a healthy lifestyle.
• Drink plenty of water
• Manage daily stress
Skin Cleansing
For daily hygiene, use a mild cleanser. Remove facial make up
completely. Use lukewarm water for all cleansing. Rinse the skin
thoroughly to remove cleansing materials from the skin surface. Gently
pat dry and avoid rubbing.
Skin Moisturizing
In "moisturizing," water is added to the skin. Moisturized skin is more
flexible and pliable than dry skin. Application of moisturizer immediately
after washing or bathing helps keep water within the skin. Skin
moisturizers: (1) improve hydration (moisture content) and (2) add a
"protective" or occlusive layer on the skin surface to help hold moisture
within the top layers and keep it from being lost to the environment.
The protective layer provides a barrier to water loss. Therefore, water
remains in the upper layers of the epidermis and makes the stratum
corneum more flexible.
A large number of creams and lotions are available. It is useful to read
product labels to check for certain ingredients. One of the most
common ingredients for increasing hydration is glycerin, which holds
onto water within the outer layers following application. Glycerin is a
humectant type of moisturizer because it attracts and binds water in the
skin. . In dry, scaly skin, desquamation does not occur properly,
resulting in the formation of visible scales. Glycerin assists the process
of desquamation of the outer layer of stratum corneum and reduces
scaling. A second type of ingredient serves as a barrier or occlusive
when applied to the skin. These materials include petrolatum, mineral
oil, and certain plant oils.
They are lipid in nature and protect the skin by minimizing water loss
from the epidermis and by providing a barrier to intrusion from the
outside and to loss of water from the skin layers beneath it.
A second group of skin care materials are the alpha hydroxy acids,
known as the fruit acids (glycolic acid, lactic acid, etc.), and beta
hydroxy acids (salicylic acid). These materials create a smoother skin
surface by hydrating the surface layers and weakening and breaking
the attachments between the stratum corneum cells. This process,
known as exfoliation, assists in the removal of surface dry, scaly
patches from the surface. This process creates a smoother surface
composed to cells which are more hydrated than the dry scales that
were removed.
Cancer Awareness
We advise periodic evaluations of any marks, moles, or pigmented
areas by a trained health care professional. Any mole that changes in
size or has an irregular border must be checked. Prevention of skin
cancer involves avoiding sun damage and detecting trouble spots
early. Be aware of changes in your skin and have them evaluated.
spots early. Be aware of changes in your skin and have them
Adult Skin Care
An individual's skin care regimen should include basic elements, as
well as those tailored to specific needs and lifestyles. For the early
adult (20-35 years), we recommend cleansing with a non-soap product
and rinsing well and moisturizing, particularly in cold weather.
Application of sun screens and sun blocks on a daily basis at an SPF
value of 15 is essential. For early signs of damage, such as uneven
pigmentation or fine wrinkles, a retinoid product should be considered.
Control of acne is often important for this age group.
For the middle adult years (35-65), cleansing, moisturizing, sun
protection, and use of retinoids are recommended. Acne can be
problematic for this group, as well as early adults and teenagers. For
persistent acne, various medications and treatments are available.
Individuals may consider restorative techniques, such as the chemical
peel, dermabrasion, or laser resurfacing, to correct the damage caused
by sun exposure.
For the older adult (over 65 years), the cleansing, moisturizing, and sun
protection routines should be followed. Restorative techniques can
provide noticeable improvement in skin damaged by sun exposure.
Regardless of age, sun exposure should be minimized and sun
screens and sun blocks applied routinely. They will prevent additional
A Guide to Skin Care Products
Over the counter skin care products, such as lotions, creams, and color
cosmetics, generally do one or more of the following: (1) Condition by
moisturization; (2) protect from moisture loss and irritation with a
protective or occlusive layer; (3) cleanse soils and makeup; (4)
minimize irritation; (5) improve appearance; and (6) improve the
comfort and feel of the skin.
Skin care products usually contain a large number of ingredients. They
perform three types of functions: (1) For the care of the skin, the
ingredients include moisturizers, occlusive materials, protectants,
sunscreens (ultra violet light absorbers), cleansers (known as
surfactants), and other conditioners. (2) For the experience during
product use, they contain fragrance, colorants, and materials to
produce a pleasing feel on the skin during
application. (3) For the product integrity and shelf life, they contain
ingredients such as thickening agents, viscosity control agents, and
preservatives. These ingredients insure that the product will maintain
its integrity from manufacture to complete use by the consumer.
Ingredient Function
A knowledge of the effects of specific ingredients on the skin is very
useful in evaluating skin care products. Skin moisturizers are
designed to improve or maintain skin condition by providing water
(hydration) in the upper layers of the stratum corneum. Skin with the
proper level of hydration is pliable, supple, and without scales/flaking.
Skin can be moisturized with a variety of ingredient types. Often,
several moisturizers are present in the same formulation. An
humectant functions as a hydrating agent because it attracts and
binds water to the upper layers of the skin. Glycerin is an humectant
commonly found in creams and lotions. In dry skin, the desquamation
process is not normal and the outer layer of the stratum corneum is not
shed properly, resulting in the build up of cell aggregates that are
observed as skin flakes. Through the process of holding water in the
skin, glycerin is believed to facilitate the process of desquamation of
the outer layer of stratum corneum and reduces scaling. An occlusive
ingredient retards the evaporation of water from the skin surface,
thereby increasing the water content in the upper layers. A skin
protectant protects injured or exposed skin from harmful or annoying
stimuli. Examples of such “annoying” stimuli include certain types of
cleansing agents, powders, and certain types of cosmetics. These
materials can damage the skin by disrupting the lipid bilayers in the
upper stratum corneum and/or by penetrating through the stratum
corneum to cause an inflammatory response in the epdermis. An
emollient maintains a soft, smooth, and pliable appearance. It also
remains on the skin surface, reduces flaking, and/or acts as a lubricant.
An exfoliant assists in the removal of surface dry, scaly patches from
the surface. This process creates a smoother surface composed to
cells that are more hydrated than the dry scales that were removed.
Cleansing agents (surfactants) remove soils, including sebum, oils,
dirt, sweat, cosmetics, etc., from the skin surface. These materials go
to the skin surface and interact with the soils to lift them from the skin
surface. Surfactants vary considerably in their effects on the skin itself.
Certain surfactants are classified as harsh because they disrupt the
lipid bilayers in the stratum corneum, presumably increasing the
permeability to other materials. Some
surfactants penetrate through the stratum corneum and cause an
inflammatory response in the epidermis. Others are much less irritating
and are more well suited to skin cleansing applications.
Ingredients classified as biological additives are derived from some
biological (plant or animal) source and incorporated into the skin care
product. The biological origin, however, does not automatically insure
that they have biological activity in the skin. Ingredients such as
emulsion stabilizers, viscosity decreasing agents, bulking agents,
and binders influence the product physical properties to create
pleasing formulations that are shelf stable from manufacture to
purchase and use by the consumer. Preservatives prevent the
contamination by microbial organisms. Fragrance components and
colorants provide desirable qualities during product application and
Label Information
You can learn a great deal from the label, particularly if you can
determine the functions of the ingredients. The purpose of this section
is to provide that information. Federal regulations in the United States
require the ingredients to be listed on the label, in the order of the
amount in the product. Unfortunately, you cannot learn the absolute
amount of the materials from the label. In most cases, the benefit to
the skin of moisturizers and protectants depends upon the amount
applied to the skin. More is not necessarily better, but certain minimum
amounts are needed to product the expected effects. You can learn
about the function or purpose of each ingredient by looking it up in the
index below.
Reading Between the Lines
There are a few things to be mindful of when you look at the label for
ingredients and product claims. (1) Notice how often water is listed as
the first ingredient. This means that the product is mostly water. Water
is an excellent skin conditioning agent – the best, in fact. The task is to
provide water to the skin in such a way as the skin retains it in order to
be smooth and supple. Putting water on the skin surface is easy, but
keeping it there requires other strategies. (2) The ingredient names are
fancy and complex, but they may be quite common. (3) Fragrances
have a large number of individual components, none of which are at
high levels. They are usually the ingredients far down on the list. (4)
Some of the ingredients are there to keep the others together in a
pleasant, uniform, and smooth formulation.
