Derma E Evenly Radiant Overnight Peel 2 ozA unique fragrance-free blend of alpha hydroxy acids including glycolic acid and other fruit acids that gently exfoliates. It contains 5% AHA at a pH of 3 for extremely effective and safe removal of dead skin cells. (This is the optimal balance of percentage concentration and pH, that produces the most effective exfoliation). This nonabrasive formula retexturizes your skin so pores look smaller, helps improve skin tone, evens out pigmentation and fades age spots for smoother, softer, younger-looking skin. Please note: Alpha Hydroxy Acids need to have a low pH to work effectively. They must be in a pH environment of 4.5 or less in order to dissolve the lipid bonds between the surface skin cells. While some products may appear to have higher concentrations of AHAs, this is often compensated for by increasing the pH level to buffer the natural acidity, therefore making the product less effective.
