According to a study of Pharmacological Laboratory of Tianjin Pharmaceutical Inspection Institute, scutellaria baicalensis extract has significant anti-inflammatory activity. It can inhibit xylene-induced ear swelling in mice. Also it has obvious inhibitory effect on itch reaction induced by low molecular weight dextran and itch reaction induced by histamine in guinea pigs.

It indicates that scutellaria baicalensis extract can antagonize histamine, and has strong anti-allergic effect.

The study also showed that sunscreens containing 24% zinc oxide (a light stabilizer) had a sun protection factor (SPF) of 17.8; while adding 5% scutellaria baicalensis extract, SPF is as high as 22.7. This indicates that scutellaria baicalensis extract can be used as a safe and effective cosmetic sunscreen. It has strong UV-absorbing ability in the range of 320nm-400nm (UV-A).

· Anti-aging
Scutellaria baicalensis extract can eliminate free radicals, significantly inhibiting formation of lipid peroxides. Moreover, it can enhance skin’s antioxidant capacity. With age and ultraviolet radiation, human telomeres (ends of DNA) are gradually shortened, which causes body to age and affect fibroblasts. The fibroblasts provide collagen to skin. In a research published by the World Health Organization, researchers used ultraviolet light to illuminate skin cells. In skin cells not containing scutellaria extract, the telomere length was reduced by nearly 70%. However, in skin cells applying scutellaria extract, the telomeres recovered to 64% of their original length. It indicates that scutellaria baicalensis extract can increase skin metabolism, increase skin elasticity. Meanwhile, it has anti-wrinkle and anti-aging effect.
· Skin-whitening
Scutellaria baicalensis extract has strong tyrosinase inhibition activity. It can reduce the formation of melanin in the skin, and has certain whitening and freckle effects. A study invites 15 volunteers to test whitening effect of cutellaria baicalensis (13 cases had chloasma or freckles, 2 cases had no obvious spots but the skin is dark, all women). The experimental results show that 8 of the 13 with pigmentation are markedly effective (skin lesion fading rate is above 60%), and the effective rate was 61.5%; 3 cases are effective (skin lesion is reduced by 20%-60%), and the effective rate is 23.1%; 2 cases are ineffective (less than 20% reduction in lesions), and the ineffective rate is 15.4%. In 2 cases with darker skin, the melanin is significantly reduced after using the experimentally products, and the skin become white, with a total effective rate of 84.6%.
