This product uses the third-generation fruit acid — gluconolactone (PHA) as the core exfoliating ingredient. Its molecular weight is much larger than traditional AHAs, it only acts on the outermost layer of the skin with gentle penetration, and almost never causes stinging, redness or barrier damage. It is one of the gentlest chemical exfoliating ingredients currently available. PHA also has moisturizing and antioxidant capabilities. While gently metabolizing dead skin cells, it locks in moisture, scavenges free radicals, and soothes redness and discomfort. Long-term use can refine pores and improve roughness, leaving the skin stable and translucent. The formula is compounded with panthenol, asiaticoside and ceramides to strengthen the skin barrier, soothe and repair sensitive redness, and further reduce the risk of irritation. The product has a refreshing watery texture, which can be patted directly on the face by hand or wiped with a cotton pad. It is burden-free even for daily use. Specially designed for sensitive skin, barrier-damaged skin, redness-prone skin and acid beginners, it is an ideal choice for sensitive skin to achieve gentle exfoliation.
