September 2023 in “Molecules” This study found that encapsulating coffee berry extract in nanoliposomes improved its stability, reduced toxicity, and enhanced its anti-aging effects on skin elasticity and lightening more than free extract.
October 2023 in “International Journal of Cosmetic Science” In this study, researchers developed WS Biotin, a new water-soluble form of biotin, and found that it significantly improves water solubility compared to free biotin and enhances hair-related keratin expression, gene activity for hair growth in vitro, while also reducing melanin content in skin cells.
