Core Skin Care Benefits

1. Soothing Anti-Inflammation & Anti-Sensitivity

As its signature function, stearyl glycyrrhetinate helps reduce skin inflammatory response, and relieves redness, itching and irritation. It effectively soothes sensitive skin, alleviates discomfort caused by allergic reactions and external stimuli, and supports the skin's self-repair process after minor damage or external stress.

2. Brightening & Dark Spot Lightening

It inhibits tyrosinase activity to reduce melanin production and deposition. Widely used in brightening and whitening formulations, it helps lighten dark spots, fade pigmentation and even out overall skin tone.

3. Antioxidant & Anti-Aging Support

With natural antioxidant properties, stearyl glycyrrhetinate helps neutralize free radicals and reduce oxidative damage caused by environmental pollution and UV exposure. It helps slow premature skin aging, reduce the formation of fine lines and wrinkles, and maintain skin elasticity.

4. Moisturizing & Barrier Maintenance

It delivers reliable moisturizing performance, helps increase skin moisture content, improve dry and rough skin texture, and keep skin soft, smooth and hydrated. It also regulates stratum corneum metabolism to prevent excessive exfoliation, supporting the integrity of the skin's natural barrier and maintaining skin water-oil balance.

5. Antibacterial & Acne-Prone Skin Support

It exhibits inhibitory activity against a range of bacteria and fungi, helping control microbial growth on the skin surface. This property makes it a popular active for anti-acne and antibacterial skincare products, supporting skin health and reducing infection-related skin concerns.
