Abstract
We conducted a 24-week clinical study in 20 women with skin and scalp hair problems (e.g., skin dryness, pigmented spots, roughness, thinning hair, and hair loss) and symptoms of ketsuo or kekkyo to investigate the effects of kamishoyosangoshimotsuto extract (KGS1) on skin condition and hair properties. Skin evaluation revealed significant improvements in stratum corneum moisture content, skin texture score, and spot brightness. Hair evaluation showed significant increases in hair thickness and hair breakage strength. Furthermore, we visually analyzed the effects of KGS1 on skin condition using facial photographs taken before and after test product treatment. In almost half of subjects, facial color and the skin color of spots were visibly brightened, skin dullness was improved, and skin luster was increased.
