What is difference in the AHA product that costs $100.00 versus the $20.00 product?
The price of an AHA product (or any skin care product for that matter) does not in any way indicate that it is a superior product or that it is even as effective as the less expensive one. AHA products should be chosen solely on the basis of (1) Type of AHA, (2) Percentage of AHA (3) Overall pH level. In many cases, more expensive simply means more expensive.
