During the past 10 years, great strides have been made in the field of nonsurgical facial restoration, and estheticians must be aware of these new techniques in order to advise and educate their clients. The modern esthetician should be a source of knowledge for their clients and develop a working relationship with a facial cosmetic surgeon, general cosmetic surgeon or cosmetic dermatologist.
Advances in skin care
As people grow older, two factors contribute to an aged look: a decreasing amount of fat, which results in the loss of contour; and the loss of collagen and elastin, which contributes to wrinkling. Known as lipoatrophy, this decrease causes a reduction of facial fullness, contour and shape.
Some of the most significant advances in skin care include the introduction of low-pH nonbuffered glycolic acid and tretinoin. Because tretinoin is contained in prescription medications and is out of the realm of esthetics, the focus of this article will be on low-pH nonbuffered glycolic acid.
