• With natural biological activity, it can penetrate the superficial skin layer to repair damaged keratin gaps, soothe skin redness, swelling and sensitivity caused by external stimulation, and accelerate skin barrier recovery.

• In addition, it has mild antibacterial, anti-inflammatory and antioxidant effects, which can inhibit the growth of harmful bacteria on the skin surface, reduce inflammatory reactions, scavenge free radicals, delay skin aging, and improve dull and loose skin texture.

• The product has mild properties, no irritation, no stickiness after application, stable formula performance, and will not affect the transparency and texture of finished products.
