Peter Thomas Roth's 20% Complex Glycolic Solutions Jumbo Peel Swabs are single-use peels packaged individually. Each pouch contains a large (OK, "jumbo") swab that's saturated with an AHA exfoliating solution formulated within the pH range AHAs need to exfoliate. Although there's much to love about this convenient way to do a peel at home, the product's name is a bit misleading.By referring to a "20% Complex", the brand isn't telling you upfront how much of the AHA (in this case, glycolic acid) you're getting. This is frustrating because AHAs have an ideal concentration range if they are to exfoliate skin. Based on glycolic acid's placement on the ingredient list, we suspect you're getting at least a 10% concentration, but we also know a lot of people will think this peel contains a high concentration of 20% glycolic acid because of its name. We posed this question to the brand, and they confirmed that the swab solution does not contain 20% glycolic acid.
