Did you know that the outer skin layer completely rejuvenates itself over the course of a month? In every fifteen years, there is a total overhaul of all the skin cells in your body, including the ones lining the inner layer of your skin. These changes are a part and parcel of the normal skin cycle. When the skin does not follow the cycle properly, dead skin cells tend to build up. Exfoliation is the process through which you can remove the dry and flaky surface cells to reveal younger looking skin from below.
As we age, the surface skin cells take more time to fall off, leading to the build-up of old cells. The uneven complexion that emerges is not often a pretty sight. In such instances, exfoliation is very much necessary to regain skin's luster and brightness. The process evens out skin tone, unclogs pores, and also prevents and treats acne. For best results, always moisturize your skin after you exfoliate it.
The history of exfoliation can be traced back to ancient Egypt, where its merits were discovered and harnessed for the first time. The exfoliation techniques range from the relatively simple manual ones to procedures performed by medical professionals.
In mechanical exfoliation, a product having an abrasive, rough consistency is used to rub off dead skin cells. Facials at salons typically employ this technique. You can achieve a similar result using a loofah, a sponge, a brush, or even a wash cloth.
In microdermabrasion, the upper layers of the epidermis are gently removed to increase the cellular turnover rate. This, in turn, stimulates the production of collagen and elastin in the dermal layers. Even a single session is enough to give you a brighter skin tone or reduce the appearance of your pores. You can also use this technique to reduce hyper pigmentation and scarring.
In chemical exfoliation, a chemical solution makes the dead skin cells fall off. This procedure can make the skin smoother and wrinkle free. In chemical peeling, you can opt for alphahydroxy acid peels, betahydroxy acid peels, retinoic acid peels, or trichloroacetic acid peels. Bear in mind that these chemicals are strong and need to be applied only by professionals.
