How to Use

After cleansing, apply an appropriate amount evenly over the face while avoiding the eye area. COSRX states that it can be used once or twice daily, but because this is a 20% high-strength formula, starting gradually can be more comfortable for new users. Use sunscreen during the day.

Tip: When using it over the full face, be careful when combining it with other strong active ingredients such as retinol, AHA/BHA or high-potency Vitamin C, as irritation may occur.
