AI Technical Summary

Technical Problem

Existing whitening agents are unstable under light and heat, have safety hazards, and are not suitable for sensitive skin, so it is difficult to develop whitening active ingredients with multi-channel whitening effects, safety and stability.

Method used

Nanovesicle compositions of Chinese torreya fruit, scutellaria baicalensis root and rohan fruit are prepared by wall breaking treatment, centrifugation, filtration, chromatography and ultrafiltration concentration, and nanovessels with a double-layer membrane cystic structure are formed, and combined with application to achieve skin whitening effect.

Benefits of technology

This composition can induce autophagy, promote melanosome degradation in skin cells, significantly reduce melanin accumulation, have whitening and anti-aging effects, and is safe and stable.
