Can retinol help to restore a youthful glow to your skin?

With so much hype and misinformation associated with the marketing of anti-aging skin care products, it can be difficult to determine what actually works for improving the texture and appearance of aging skin. One skin care ingredient that’s been promoted heavily for skin rejuvenation is retinol. Is there truth behind the widely claimed benefits of usin retinol for skin rejuvenation?

Retinol is a purified form of vitamin A which is thought to stimulate collagen product when applied directly to the skin. It does this by stimulating skin fibroblasts, the cells that produce collagen, and by inhibiting the action of enzymes that promote breakdown of the skin’s collagen support structure.

The limiting factor with many skin care products that advertise that they promote collagen production is that the molecules are unable to penetrate deeply enough to gain access to the dermis where the fibroblasts are located. Hence, they’re unable to stimulate collagen synthesis despite their advertising claims. This where the retinol molecule is different. It has the ability to penetrate the outer layer of the skin, the epidermis, and gain access to the inner dermis where it can stimulate the fibroblasts to produce more collagen.

The ability to gain access to the dermis and stimulate collagen production gives retinol the ability to improve the appearance of lines and wrinkles as well as counteract some of the skin damage created by years of sun exposure. Retinol also increases the thickness of the outer skin layer, the epidermis. This results in a skin with a finer, more translucent texture as well as a reduction in skin roughness.

Do studies confirm that retinol works to improve the appearance of aging skin? A study performed on 31 subjects to test the effects of retinol on skin texture and appearance. The individuals had a 0.4% retinol solution applied to one arm and a placebo to the other. Not only did the arm that received the retinol show improvement in skin roughness and texture, but a skin biopsy revealed an increase in the precursors of collagen synthesis, suggesting that collagen production was being stimulated. In addition, retinol has been used by dermatologists and physicians for many years as an anti-aging cream with good results.

It appears that retinol is effective both in improving the texture of the skin as well as reducing the appearance of fine lines. By stimulating collagen production, it may also compensate for some of the solar damage accrued over the years. Although you can buy dilute retinol formulations over the counter, they may not have the same benefit as prescription formulations available from your doctor. Because prescription strict retinol in the form of Retin-A and its derivatives may be too irritating for some people’s skin, it may be prudent to start with a lower strength, non-prescription formulation and advance to the prescription form if results aren’t achieved. Remember to always wear a sunblock when using retinol since it increases sensitivity to the sun.
