This is a functional exfoliating toner. It uses mild AHAs such as glycolic acid and lactic acid as core exfoliating ingredients. By accelerating keratin metabolism, it promotes the shedding of surface melanin, improves acne marks, sun spots and dull skin tone, while unclogging pores and improving rough skin and closed comedones. The formula is compounded with brightening ingredients such as niacinamide, tranexamic acid and vitamin C derivatives, which inhibit melanin production through multiple pathways, fade existing pigmentation, and evenly brighten skin tone, achieving the dual-effect synergy of "exfoliation + spot fading & brightening". Moisturizing ingredients such as hyaluronic acid and trehalose are added to relieve dryness caused by fruit acids and maintain skin hydration. The product has a clear watery texture. It can be wiped with a cotton pad or patted by hand after cleansing. Daily use can gradually improve dullness and spots, leaving the skin glowing from the inside out. Suitable for people with brightening needs, uneven skin tone, shallow acne marks and sun spots. It is a cost-effective daily product combining skincare and exfoliation.
