intrinsic aging and hormones
Expression lines developed from pressing on the face tend to be
vertical
Most typical expression lines are
depressions from repeated muscle movement
At what age range do bones in the skull appear more obvious because of loss of subcutaneous fat
60+
at what age range do expression lines begin to show; upper eyebrow skin begins to lose elasticity?
20s
At what age range does cartilage of nose and ears expand due to gravity?
50s
At what age range does cumulative damage from years of sun exporsure become more visible?
menopause
At what age range does production of estrogen begin to slow?
40s
At what age range does skin begin to droop because of gravity and continued loss of collagen?
30s
At 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
At what age range do bones in the body and face begin to shrink?
50s
At menopause, women begin to produce more estrogen and as a result, the production and repair of collagen in the skin decreases
False
Changing hormone levels affects lipid production between cells in the skins barrier.
True
Elastosis begins to be visible in the twenties and thrities and becomes more pronouced in the forties and fifties
True
In the mid- twenties, collagen in the skin begins to diminish 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 sksin occur in the dermis as the rate of collagen and elastin replacement decreases
True
Muscles of the face are different from the muscles in other parts of the body in that the muscles of the face are attached to the bone below which drags 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 experiecne 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 diminishes, 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 reduction in estrogen will have a significant effect on the functioning an apperance 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 is influenced by intrinsic factors.
