CLEO Clear Skin Award Winner 2019, Best Exfoliator for Acne-prone Skin! Exfoliating cream that does not need to be washed off. It consists of glycolic acid (a type of AHA) that helps with gentle exfoliation. You might feel tingling sensation due to AHA penetration. How to Use: After toner, apply thinly and a pea-sized amount, followed by moisturizer. There will be a bit of tingling sensation but it is normal. If you have sensitive skin, please test small amount on your face first.
