With aging, the outer skin layer (epidermis) thins even though the
number of cell layers remains unchanged. The number of
pigment-containing cells (melanocytes) decreases, but the remaining
melanocytes increase in size. Aging skin thus appears thinner, more
translucent. Age spots or liver spots may appear in sun-exposed
areas. Changes in the connective tissue reduce the skin's strength
and elasticity. This is known as elastosis and is especially
pronounced in sun-exposed areas.
