Wow! A must have for anyone! I was so scared to try these as I have such sensitive skin that normally can't tolerate any glycolic or sacilyic acid. However, the chamomile + vitamin K + billberry extract in these totally counteracts the side effects of the acids, calming and soothing my skin. With in a month of use I found my skin was less red&splotchy, overall tone + texture had greatly improved, and skin was brighter + healthier looking! Try them today!
