The concentration of the AHA/BHA is less than 3% in that product. The lower concentration is designed to be a very gentle agent to help shed dead skin cells when used overtime (it definitively will not be as exfoliating as in higher concentration as in a scrub or exfoliating treatment), and it also has natural moisturizing and conditioning capabilities. AHA/BHA are some of the most amazing natural ingredients that have been proven to significantly improve the condition of the skin.
