Are there any side effects from using an alpha hydroxy acid (AHA) to exfoliate?
Most people will experience a tingling or a stinging sensation when they begin to use an AHA. Dryness, flaking, slight redness or temporary breakouts may also occur within the first to second week of use. These symptoms are quite normal and will usually disappear as the skin builds up tolerance. Use a moisturizer regularly because dryness can occur, and always use a sunscreen when exfoliating.
