A 50% glycolic acid peel can cause redness and dryness for 7+ days. The most important thing you can do is treat your skin with the utmost care over the next few weeks. Avoid exposure to the sun, harsh products such as RetinA, and skip any skin creams containing Vitamin C. Use an extremely gentle moisturizer on your face, 2-3 times a day, to keep your skin hydrated. If the redness and dryness continue after 2 weeks, contact your physician, who may want to add a steroid cream.
While all of this babying of your skin may seem like a big undertaking, the results of your 50% glycolic acid peel can be exceptional. Winkles, sun damage, and even acne, can be almost erased, leaving smooth, youthful skin behind. Be sure to always seek the care of a board certified, experienced physician (with chemical peels/aesthetic/cosmetic surgery), as they will be able to steer you towards the most appropriate procedure for you, as well as provide the best pre, during, and post treatment possible.
