YOUR SKIN
The skin is the largest organ of the body, and is significantly affected by the aging process. Estrogen receptors have been detected on the cellular components of the skin and lower levels of estrogen influence the skin-cell metabolims. Changes in the skin collagen leads to diminished elasticity and skin strength. There is a distinct reduction of collagen production after menopause. Changes in vascularity are found following menopause. Dermal blood flow decreases significantly in postmenopausal women.
Repair functions in skin are regulated by a group of chemicals called ‘cytokines’. Included in these are epidermal cell growth factor (ECGF), transforming growth factor (TGF), and angiogenesis factor. AF stimulates the rebuilding of the microvascular system within the skin. TGF and ECGF stimulate rapid cell proliferation for the replacement of dead or damaged cells.
Excessive exposure to UV rays causes oxidation of the collagen and elastin fibers in this skin. This, in turn causes ‘crosslinking’. Cross-linking causes the collagen in the skin to become tangled and stiffen. This results in sagging and loss of skin...
