What is AHA body lotion and should you use it?

AHA body lotion is body moisturizer with alpha hydroxy acids such as lactic acid or glycolic acid. The acids help loosen dead skin cells so rough patches feel smoother and look less dull.

People usually reach for it on keratosis pilaris, rough elbows, flaky legs, or skin that feels bumpy even after moisturizing. It can help, but it is still an active product, so sensitive skin may sting if you use too much too quickly.

The practical move is to start slowly, moisturize on top if needed, and patch test if your skin tends to react. It is a treatment lotion, not just a fancy scented cream.
