intrinsic aging and hormones
At menopause, women begin to produce more estrogen and as a result, the production and repair of collagen in the skin decreases
False
Chnaging hormone levels affects lipid production between the cells in the skins barrier
True
Elastosis begins to be visible in the twenties and thrities and becomes more pronounced in the forties and fifties.
True
In the mid-twenties, collagen in the skin begins to deminish at the rate of 2 percent per year
False
Many epidermal changes associated with aging can be treated by the esthetician.
True
Most of the physiological changes of the skin occur in the dermis as the rate of collagen and elastin replacement decreases
True
Muscles of the face are different from muscles in other parts of the body in that the muscles of the face are attached to the bone below which drages on the skin causing sagging with repeated movement
False
Nasolabial folds run from the corners of the nose to the mouth
True
Rhytids are caused mostly by the repetition of facial expressions or by cumulative sun exposure
True
Some menopausal women experience a flare in acne. As estrogen levels drop, another female hormone, progesterone, prompts the sebaceous glands to produce more sebum
False
The loss of skin elasticity in the upper eyelid is called browtosis
True
The rate of epidermal renewal, normally about 28-30 days, slows with aging. The resulting epidermal changes are most effectively treated with humectants and emollients.
False
To reduce the amount of extrinsic lines and wrinkles on the face one might be tempted to refrain from making any facial expressions
False
With aging reduced lipid production causes gaps in the intercellular lipid structure which leads to easier penetration by irritants and allergens. Older skin becomes more sensitive because of increased thinness and poor lipid barrier function.
True
With aging the production of sebum diminshes, causing superficial dehydration.
True
Estrogen increases fibroblast activity which stimulates both collagen and hyaluronic acid production. It also reduces the size and activity of sebaceous glands and increases cellular mitosis in the epidermis. In menopause a redcution in estrogen will have a significant effect on the functioning an appearance of a woman's skin so much so that there is often the comment on "sudden aging overnight"
True
The skins lack of ability to resist gravity it influenced by intrinsic factors

30s
At what age range is elastosis much more apparent; jowls may begin to form?
40s
At what age range past the 20s might acne flares start to occur, caused by hormonal shifts?
50s
Expression lines developed from pressing on the face tend to be:
Vertical
Most typical expression lines are:
Depressions from repeated muscle movement
