The skin is constantly generating new skin cells at the lower layer (the dermis) and sending them to the surface (the epidermis). As the cells rise to the surface they gradually die and become filled with keratin. These keratinized skin cells are essential because they give our skin its protective quality. But they are constantly sloughing off to make way for younger cells. As we age the process of cell turnover slows down. Cells start to pile up unevenly on the skin’s surface, giving it a dry, rough, dull appearance. Exfoliation is beneficial because it removes those cells that are clinging on, revealing the fresher, younger skin cells below. Exfoliant products containing alpha hydroxy acids, such as glycolic or lactic acids, increases the turnover of collagen production resulting in the removal of fine lines and the appearance of smoother, healthier looking skin.
It is possible, however, to over-exfoliate, especially on the delicate skin of the face. Over-exfoliating will dry and irritate the skin.
What You Should Know About Facial Exfoliation:
•Be extra careful with the delicate skin of your face. •It’s easy to over-exfoliate. Talk to a good esthetician about the product and frequency that is best for your skin. Your should be especially cautious if you have sensitive or aging skin. •Be careful not to overdo microdermabrasion. It can make thin, aging skin even thinner if you get too many treatments too quickly. •Don’t over-exfoliate, especially in summer or in very sunny climates. You’re making it easier for your skin to be damaged by the sun. •Never use body scrubs on the face. They’re too rough. •Be very careful with peels. Don’t get one peel and then go somewhere else to ask for another. You can remove too much of your protective layer and end up exposing the living dermis. Again, be careful about going out in the sun afterwards. •Never wax if you’ve had a peel recently. It might expose raw, living skin, which will have to scab over to heal.
