BioSil Hair, Skin, Nails from Natural Factors helps restore your body's 3 beauty proteins to more youthful levels. Around age 21 the body begins to slow down production of the beauty proteins responsible for maintaining healthy skin, nails and hair. By age 30 the aging effects are already visible. Our formula includes a patented choline and silicon complex called ch-OSA designed to help reverse this process. The ch-OSA is delivered in a potency to encourage your body to produce and protect collagen, keratin and elastin. Watch those wrinkles and fine lines fade away with help from BioSil Hair, Skin, Nails.
