External elements, known as
extrinsic factors, can prematurely age your skin. Excessive exposure
to the sun is an extrinsic factor that aids in damaging your
skin. Your skin naturally ages intrinsically, or internally,
but exposure to the sun accelerates the aging process.
Sunlight harms your skin, most
particularly the upper layer of skin known as the epidermis.
The ultraviolet light of the sun damages fibers in the skin referred
to as elastin. Dermatologists have a special term, photoaging,
for the premature aging caused by exposure to the sun's rays
and this condition occurs over a period of many years. Fair skin
tends to show signs of photoaging more profoundly than dark skin
because of the level of pigmentation in the skin.
Signs of damage due to exposure
to sunlight include wrinkles, roughness, leathery texture, age
spots, blotchy pigmentation and a reduction of flexibility. Skin
that has been hurt by the sun may also be more prone to bruising.
A major cause of skin cancer is the damage done by exposure to
the sun. Exposure to the sun can also include tanning since you
are still putting your skin into contact with simulated sun rays. |
