This product uses high-purity lactic acid as the core exfoliating ingredient, which belongs to the second generation of AHAs. With a larger molecular weight than glycolic acid, it acts more gently and slowly, is less likely to cause redness and stinging, and has good moisturizing ability. It removes dead skin cells while replenishing moisture to the skin, avoiding the dryness problem caused by traditional fruit acids. The product can gently metabolize dead skin cells on the skin surface, improve dull skin tone, rough texture and shallow acne marks. Long-term use can refine pores and brighten skin tone, leaving the skin with a transparent glow. The formula is compounded with hyaluronic acid, ceramides and oat extract to further enhance moisturizing and soothing effects, repair the skin barrier and reduce the risk of acid irritation. The serum has a hydrating and light texture, easy to spread and absorb. It is recommended to use 2-3 times a week, with better effect when used at night. Suitable for dry, combination dry, sensitive skin and users trying fruit acids for the first time, it is the first choice for gentle exfoliation beginners.
