Can chemical peels flatten cheeks? (photos)

TCA peels can vary in depth, but do not usually extend past the dermis of the skin. The cheek volume loss is likley not related to the TCA peel. Best, Dr. Karamanoukian Los Angeles

The changes you noticed with your cheeks are in no way related to the chemical peels.  I would encourage you to continue with regular maintenance peels, especially since you have enjoyed the improved appearance of your skin so far.  Your cheeks will naturally deflate as you get older.  The best way to restore cheek volume is to replace it with filler, Sculptra, or fat transfer, which works at a level deep to the skin.  The peels will only work at the skin level to maintain and stimulate new collagen production leading to thicker, smoother skin.  A comprehensive approach, one that addresses the deep and superficial changes, will give you the best, most natural results over the long term.
