Beauty Focus MultiBeauty features both grapefruit and rosemary extracts, which is a clinically proven combination that helps protect your skin (and important skin proteins like collagen and elastin) from damaging environmental stressors, including photoaging. It also contains Biotin, also known as vitamin B7, which is clinically proven to revitalize both your hair and nails by supporting healthy cell growth and helping your body produce much-needed keratin.\* Keratin is the protein our nails are made of, meaning its production is vital to keeping your nails strong and resilient.
