Wrinkles and Good Skin
Your skin changes as you age. You might notice wrinkles, age spots and dryness. Your skin also becomes thinner and loses fat, making it less plump and smooth. It might take longer to heal, too.
Sunlight is a major cause of skin aging. You can protect yourself by staying out of the sun when it is strongest, using sunscreen with an SPF of 15 or higher, wearing protective clothing, and avoiding sunlamps and tanning beds. Cigarette smoking also contributes to wrinkles. The wrinkling increases with the amount of cigarettes and number of years a person has smoked.
Many products claim to revitalize aging skin or reduce wrinkles, but the Food and Drug Administration has approved only a few for sun-damaged or aging skin. Various treatments soothe dry skin and reduce the appearance of age spots.
Wrinkles now have a greater social impact because people live longer. Science and hedonism overlap in the search for causes, treatments and prevention of wrinkles.
The cosmetic approach to wrinkles includes:
- Photo protection
- Active ingredients
Active ingredients go well beyond simple moisturizers and exert a more complex activity in protecting skin from external injuries, nourishing it and removing its superficial layers. Transport systems and excipients are increasingly effective.
Functional agents currently include: alpha hydroxy acids (AHAs), poly-AHAs, complex poly-AHAs, retinoids, fish polysaccharides, anti-enzymatic agents, antioxidants (including ascorbic acid, pycnogenol, ursolic acid, vegetable isoflavones, vitamin E, coenzyme Q10, lipoic acid, resveratorol, l-carnosine and taurine) as well as agaricic acid and various plant extracts.
Most are topical, some can be given by mouth, even as food supplements. Cosmetics are becoming closer to drugs in preventing and treating wrinkles. Included amongst the cosmeceuticals are the anti-wrinkle agents described herein.
