sun damaged skin

The exact mechanism of sun damage is not completely understood. As a consequence of ultraviolet radiation, tissue-damaging free radicals are generated. These radicals are essentially cellular oxygen molecules that have been “energized” or activated. The result is a cascading effect that can damage millions of cells in a very short time. The effects seen visually are wrinkles, laxity of the skin, textural changes, and discoloration such as age spots. These are the major symptoms of sun damaged skin. The effects can't be seen are cellular DNA damage and impairment of the skin's immune system. These factors are important, as they are influential in the development of skin cancer. The way to minimize the skin damage is skin rejuvenation. It is accomplished through cellular regeneration and maintaining the health of sun-exposed skin. The sun is very damaging and sun avoidance as well as protection with sun block or sunscreen is essential to any maintenance regimen.

Sun skin damage treatments 3 most used.

The three most widely used treatments for skin rejuvenation or repairing sun damaged skin involves antioxidants, Vitamin A preparations, and exfoliating agents. Antioxidants are an emerging concept in skin health and maintenance. The sun's ultraviolet radiation produces free radicals that are absorbed by antioxidants. The most common antioxidants are Vitamins A, C and E, along with beta-carotene. These antioxidants are most effective when applied topically. Topical Vitamin C is the most widely used. In addition to its antioxidant activity, topical Vitamin C stimulates cell replication and collagen production. Vitamin A is available in common forms such as Retin-A (tretinoin) or retinol. Retin-A is prescription strength and is stronger than over-the-counter Vitamin A derivatives. Over-the-counter retinol, however, is very effective for sun damage. Exfoliation helps in skin thickening with more uniform pigmentation and reducing in the appearance of fine lines and wrinkles.
