Premature Aging What it is:
Sometimes referred to as “photoaging,” premature aging is the result of unprotected UV exposure. It takes the form of leathery, wrinkled skin, and dark spots.
Why it happens:
Although the causes of premature aging are not always clear, unprotected exposure to harmful UV rays break down the collagen and elastin fibers in healthy young skin, and cause wrinkles and loosened folds. Frequent sunburns or hours spent tanning can result in a permanent darkening of the skin, dark spots, and a leathery texture.

 A dermatologist or plastic surgeon can develop a treatment plan based on your needs. Treatments can include chemical peels, dermabrasion, and skin fillers.
The Bottom Line:
Premature aging is a long-term side effect of UV exposure, meaning it may not show on your skin until many years after you have had a sunburn or suntan. Avoiding UV exposure is essential to maintaining healthy skin.
