Alpha hydroxyl acid is a substance found in many skin creams. It works by increasing skin turnover—that is, it irritates your epidermis, removing dead epidermis, causing your skin to think it needs to rejuvenate and produce new cells, which has the effect of making your skin look younger. But you don't need to spend a lot of money on expensive face creams to do it; any product that contains alpha hydroxyl acid will do it; the expense on some products comes from other ingredients—not the ones that do the work.
