Aging skin

Aging skin looks thinner, paler, and clear (translucent). Large pigmented spots, including age spots, liver spots, or lentigos, may appear in sun-exposed areas.Changes in the connective tissue reduce the skin's strength and elasticity. This is known as elastosis. Over time, the dermis loses both collagen and elastin, so skin gets thinner and has trouble getting enough moisture to the epidermis. The fat in the subcutaneous layer that gives skin a plump appearance also begins to disappear, the epidermis starts to sag, and wrinkles form. The collagen and elastin fibers break, thicken, stiffen, clump together, and lose their elasticity. This results in wrinkles and aging lines. Finally, in our fifties, the skin becomes dry and is easily bruised, damaged, or broken because the sebaceous (oil) glands have decreased in size. Wrinkles are a natural part of the aging process. As people get older, their skin gets thinner, drier, and less elastic, and less able to protect itself from damage. This leads to wrinkles, creases, and lines on the skin. These fibers form the skin's connective tissue.
