Kaolin is beneficial to the skin. It is a natural hydrous silicate clay mineral with a fine texture and gentle properties, and is widely used in skincare. It has a strong oil-absorbing capacity, which can absorb excess sebum on the face, helping to refresh and control oil, tighten pores, and soothe the discomfort caused by mild oiliness and breakouts. At the same time, cosmetic-grade kaolin has fewer impurities, is more stable, and has low irritation, and is often added to mud masks, cleansing powders, and body talcum powders.
