AHA (Glycolic acid 7%) melts whiteheads in pores and improve uneven skin tone. The AHA 7 Whitehead Power Liquid includes apple water containing natural AHA and Glycolic acid that cleans up the skin and gets rid of the dead skin cells. Other properties contained in this liquid are vitamins, and natural moisturizing ingredients that can manage dead skin cells without stimulating the skin too much. Using this helps improve the appearance of the skin by making it healthier and more vital. HOW TO USE: After cleansing, soak a cotton pad and swipe a thin layer of the liquid over the skin, avoiding the eye and mouth area. Pat in gently for absorption. If the skin feels irritated, wash away after 4-5 minutes lightly with lukewarm water. After the AHA 7 Whitehead Power Liquid is completely absorbed by the skin, follow up with other essence and moisturizer. The next morning, we recommend you to use sunscreen in order to protect your skin. TIP 1. AHA 7 Whitehead Power Liquid is a high-concentrate AHA product, therefore it is best to use a small, yet sufficient amount on the areas containing whiteheads and dead skin cells for the skin to adapt to the liquid. Begin with using the product once a week, and after the skin has adapted to it, increase the usage up to 2 to 3 times a week to maintain clear skin that is free of dead skin cells, and sebum. 2. On the days you use AHA 7 Whitehead Power Liquid, do not use other exfoliating products such as products containing AHA, BHA, retinol, or vitamin C. 3. After using the AHA 7 Whitehead Power Liquid, use a serum or mask product for moisture retention and antioxidant function for a heightened moisture retention effect.
