Retinoic Acid - Treatment for Wrinkles

Wrinkles should not necessarily correspond with one's age. After all, there are about a dozen skin-care products that contain retinoic acid which are available on doctor's prescription. Retinoic acid is a chemical or substance that is derived from vitamin A. As such, it can eliminate wrinkles as it assists the skin in retaining moisture more efficiently.

However, the effectiveness of each type of skin treatment (creams, liquids, or gels) may vary from person to person. For some people, retinoic acid may work well in making many of their fine wrinkles disappear. But for others, it may have very little or no effect at all.

What causes wrinkles, and why does the skin develop such crease marks as one ages? The medical field explains it this way: As a person ages, so too does his or her skin. And in this inevitable 'growing old' process, the skin's production of oil becomes lesser and lesser, making the epidermis (the outer nonsensitive and nonvascular layer of the skin) harsh and dry. Moreover, less collagen and elastin - proteins in the connective tissue that help in maintaining the skin's suppleness - are produced by the dermis (the under layer of the skin). These simultaneous biological activities make the skin tenuous and less springy, thus making it more unresistant to wrinkles.

But it makes us wonder at times why someone who's in the 50's seems to have far less wrinkles than somebody who's ten years younger. The reason could be that the older person spends more time indoors than the younger one who chooses an active outdoor life. Being exposed to the sun very often makes skin wrinkling a lot more pronounced. Smoking is another possible cause of early wrinkling of the skin.
