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. Nu Skin conducted a clinical study, confirming the effects of this amazing supplement.  After taking MultiBeauty once daily for 12 weeks, 100% of participants noticed improvement of facial skin tightness, firmness, and smoothness, while 79% stated their hair felt stronger, and 61% said their nails appeared less brittle. \*These statements have not been evaluated by the Food and Drug Administration.
