Human skin color

skin colorskin pigmentationskin tone
In humans, skin pigmentation varies among populations, and skin type can range from dry to non-dry and from oily to non-oily.
An individual's skin pigmentation is the result of genetics, being the product of both of the individual's biological parents' genetic makeup, and exposure to sun.

Integumentary system

integumentaryintegumenttegument
The human skin is the outer covering of the body and is the largest organ of the integumentary system.
The human skin (integument) is composed of at least two major layers of tissue: the epidermis and dermis.

Melanocyte

melanocytesmelanogenesismelanocytic
Skin has mesodermal cells, pigmentation, such as melanin provided by melanocytes, which absorb some of the potentially dangerous ultraviolet radiation (UV) in sunlight.
Through a process called melanogenesis, melanocytes produce melanin, which is a pigment found in the skin, eyes, hair, nasal cavity, and inner ear.

Transepidermal water loss

transepidermalunavoidable water loss through the skinwater loss
Because it interfaces with the environment, skin plays an important immunity role in protecting the body against pathogens and excessive water loss.
Measurements of TEWL may be useful for identifying skin damage caused by certain chemicals, physical insult (such as "tape stripping") or pathological conditions such as eczema, as rates of TEWL increase in proportion to the level of damage.

Infection

It forms the waterproof, protective wrap over the body's surface which also serves as a barrier to infection and is made up of stratified squamous epithelium with an underlying basal lamina.

Hair

There are two general types of skin, hairy and glabrous skin (hairless).
On the human body, glabrous skin is found on the ventral portion of the fingers, palms, soles of feet and lips, which are all parts of the body most closely associated with interacting with the world around us, as are the labia minora and glans penis.

Fascia

Superficial fascia is the lowermost layer of the skin in nearly all of the regions of the body, that blends with the reticular dermis layer.

Light skin

The skin color of people with light skin is determined mainly by the bluish-white connective tissue under the dermis and by the hemoglobin circulating in the veins of the dermis.
Eumelanin is the dominant form of melanin found in human skin.

Somatosensory system

The four mechanoreceptors in the skin each respond to different stimuli for short or long periods.

There is significant variation in how easily people sunburn based on their skin type.

Epithelium

The outermost layer of human skin is composed of dead stratified squamous, keratinized epithelial cells.

Many conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands.

Cellulite

Vitamin A, also known as retinoids, benefits the skin by normalizing keratinization, downregulating sebum production which contributes to acne, and reversing and treating photodamage, striae, and cellulite.
Cellulite is the herniation of subcutaneous fat within fibrous connective tissue that manifests topographically as skin dimpling and nodularity, often on the pelvic region (specifically the buttocks), lower limbs, and abdomen.

Collagen

procollagencollagenscollagen fibers
It is composed of dense irregular connective tissue, and receives its name from the dense concentration of collagenous, elastic, and reticular fibers that weave throughout it.
Along with elastin and soft keratin, it is responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging.

Acid mantle

epidermal barrier
The acid mantle is a very fine, slightly acidic film on the surface of human skin acting as a barrier to bacteria, viruses and other potential contaminants that might penetrate the skin.
