Glycolic and chemical peels
It's one of most common substances used for light peels, procedures
designed to rejuvenate the skin by removing its outermost layers.
Glycolic peels can even out skin tone, fade brown spots, soften the
appearance of fine wrinkles, clear pores, and improve mild acne. In
this procedure, the acid is applied for several minutes, then
neutralized and rinsed or sponged off.
There's no recovery time after a
glycolic peel, but the results are only temporary. For a more dramatic
effect, stronger chemical peels using trichloroacetic
(try-klohr-oh-ah-SEE-tihk) acid, or TCA (T-C-A), and phenol (FEE-nawl)
can be performed by a dermatologist. These peels go deeper into the
skin, are able to treat more severe problems, and require some recovery
TCA peels are considered a medium peel and may cause swelling and
redness that lasts for days. Two or more TCA peels may be needed to
achieve the desired result. A phenol peel is generally the deepest peel
and also carries the greatest risk. Swelling may be severe and in some
people, the complexion may look permanently bleached. Today, phenol
peels are often replaced by laser resurfacing, which tends to be safer
but produces comparable results.
