6 Skin Functions Protection, Absorption, Secretion, Excretion, Temperature
Regulation, Sensation
Acid mantle protective barrier made up of sebum,
Protection lipids, sweat, and water. Forms a hydrolipidic film to
protect the skin from trying out from exposure to
external
factors.
Sensation Responds to touch, pain, cold, heat and pressure
Average internal temp is 98.6° F through evaporation,
Thermoregulation
perspiration, radiation, and insulation
Sudoriferous glands; sweat glands detoxifies the body
Excretion
by excreting excess water, salt, and unwanted
chemicals
Sebum; oily substance that protects and lubricates the
Secretion skin. Sebaceous glands; oil glands. Skin is 50 to 70%
water and slows down the evaporation of water
Transepidermal Water Loss (TEWL)
Absorption Absorbs water, ingredients, oxygen necessary for skin's health.
Epidermis Outermost Layer
Stratum Corneum (horny layer) thin and waterproof
Stratum Lucidum thin clear layer of dead skin cells
Stratum Granulosum (granular layer) composed of cells that resemble granules and
are filled w/ keratin
Stratum Spinosum (spiny layer) cells divide and change shape. Enzymes are
creating lipids and proteins
Above the dermis, single layer of basal cells. Cells
Stratum Basal
undergo mitosis to replenish the loss of skin cells
Keratinocytes Produce keratin and keeps the skin strong, flexible, and

waterproof
Melanocytes Produce pigment (give skin its color)
Langerhans Immune cells (support the immune system)
Merkel's Cells Nerve cells (sense of touch)
Dermis Cornium Curis. Broken into two layers
Papillary Connects the dermis to the epidermis
Reticular Deeper layer of the dermis made of collagen and elastin
Also known as the hypodermis. Composed of loose
Subcutaneous Layer
connective tissue (adipose tissue) 80% fat
Dry Lacks lips or sebum production.
Normal Good balance of all skin functions, circulation, oil and water, and
barrier protection
Combination Oily, dry and/or normal at the same time. T-zone imbalance is
common
Oily Excess sebum production
Sensitive Skin Skin type and condition. Fragile, reactive, easily inflamed skin
Dehydrated Skin Lacks water and can occur in any skin type
Glogau Scale Evaluates photo damage (sun) based on wrinkling categorized by
age
Uses levels to classify photo damage by the depth of
Rubin's Classification
skin changes or damage. Indicates what type of
treatment is appropriate for the skin's condition
Sebaceous Gland Oil glands
Sudoriferous Gland Sweat glands
Sebum Lubricates the skin
Sweat Glands Cools the skin
Alipidic Not enough oil
Rosacea Varying degrees of redness and inflammation
Chronic inflammation of the sebaceous gland. Build up
Acne
of cells, oil secretions, and bacteria. Lack of oxygen
Open Comedones Blackheads
Closed Comedones Whiteheads
Milia Small hard white bump. Sebum formed w/o pore
Grade 1 minor breakouts, some open and closed comedones
Grade 2 many more open and closed comedones
Grade 3 red and inflamed, many open and closed comedones
Grade 4 cystic acne, inflammation, scar formation from tissue damage
Basal Cell Carcinoma most common and least severe; open sores, reddish patches
