Summary

skin conditioning humectant photoprotective antimicrobial anti-inflammatory

Science

Mechanism of Action

Works through multiple pathways via its key bioactives: saikosaponins A and D provide anti-inflammatory and immunomodulatory effects while activating G-proteins to increase cyclic AMP levels in cells. Flavonoids like rutin and cinnamic acid derivatives scavenge free radicals and shield keratinocyte DNA from UVB damage, while polysaccharides contribute to skin conditioning and moisture retention.
