Summary

Background

Traditional medicine herbal prescriptions used for the treatment of skin disease have been developed into cosmetics. Sang‐Hyul‐Yun‐Boo‐Em (SHYBE) is a mixed herbal formula prescribed for patients with yin or blood deficiency patterns of skin disease.

A total of 46 healthy Korean females, aged 40‐59, were enrolled in this study. Objective skin assessments for hydration, elasticity, thickness and dermis density, self‐assessment, and safety assessment were conducted.

Results

Sang‐Hyul‐Yun‐Boo‐Em extract cream improved skin hydration, elasticity, and dermal density in Asian middle‐aged females compared with placebo cream, which excluded SHYBE extract and contained other cosmetic materials.

Conclusions

Sang‐Hyul‐Yun‐Boo‐Em extract cream showed anti‐aging properties in middle‐aged women. It could be recommended for aging skin with dryness, and loss of elasticity and density.
