Protection, Elimination/Excretion, Secretion; SHAPES
Sebum(oil) on the epidermis - CORRECT ANSWER - Gives protection from external factors
such as invasion by certain bacteria
Acid mantle - CORRECT ANSWER - Is the protective barrier made up of sebum, lipids,
sweat and water; part of the skins Natural Barrier function
Hydrolipidic - CORRECT ANSWER - Film that protect the skin from drying out and from
exposure to external factors; An oil water balance on the skin surface
, Acid mantle - CORRECT ANSWER - Has an average pH of 5.5; balanced pH of the skin is
important for maintaining the proper acidic level of 5.5 to protect from pathogens and for
regulating enzymatic functions
Barrier function - CORRECT ANSWER - Is the skins mechanism that protects us from
irritation and intercellular transepidermal water loss (TEWL); Damage to barrier layer causes
skin problems such as sensitivities, aging and dehydration
Transepidermal water loss (TEWL) - CORRECT ANSWER - The water loss caused by
evaporation of the skin surface
Lipids - CORRECT ANSWER - Substances that contribute to the barrier function of the
epidermis; are protective oils and are part of the intercellular matrix (fluid); protects the cells
from water loss and dehydration; 5% in the stratum corneum are ceramides
Intercellular matrix (fluid) - CORRECT ANSWER - Fluid between epidermal cells

Epidermal growth factor (EGF) - CORRECT ANSWER - Are hormones that stimulates skin
cells to reproduce and heal
Fibroblasts - CORRECT ANSWER - Cell stimulators; produce collagen and elastin; proteins
and peptides trigger these and cells to rejuvenate
Melanin - CORRECT ANSWER - Another form of protection in the skin; the pigment that
protects us from the sun
Melanin - CORRECT ANSWER - Is the pigment in the eyes, hair and skin that gives us some
