Wrinkles are a natural part of the aging process. They occur most frequently in areas exposed to the sun, such as the face, neck, back of the hands and forearms. Over time, skin gets thinner, drier and less elastic. Ultimately, this causes wrinkles – either fine lines or deep furrows. In addition to sun exposure, premature aging of the skin is associated with smoking, heredity and skin type (higher incidence among people with fair hair, blue-eyes and light skin).Treatment for wrinkles runs the gamut from topical creams and moisturizers to cosmetic procedures.
The most common medical treatments are:
- Alpha-hydroxy acids, preparations made from “fruit acids” that produce subtle improvements in the appearance of wrinkles.
- Antioxidants, creams consisting of Vitamins A, C and E and beta-carotene that improves the appearance of wrinkles and provides some additional sun protection.
- Moisturizers, which temporarily reduce the appearance of wrinkles.
- Vitamin A Acid, which helps alleviate some of the signs of aging, including mottled pigmentation (e.g., liver spots), roughness and wrinkling.
- Retinoids, Topical retinoids are creams, lotions and gels containing medicines derived from Vitamin A. These compounds result in proliferation and reduced keratinisation of skin cells independent of their functions as a vitamin. Retinoids have also been shown to reverse some of the changes due to photo-aging, i.e. sun damage. If used long term, they may reduce fine wirnkles, freckles, solar comedones (whiteheads and blackheads) and actinic keratoses (tender, dry sun-spots).
