    The Breakthrough in Collagen!

    Collagen is essential for beautiful skin, hair and nails as well as healthy bones and joints. But starting at age 21, collagen diminishes 1% per year. By age 30, the signs become visible. For years, scientists searched for a method to give the human body the ability to regenerate its own collagen. But it took BioSil's landmark discovery of ch-OSA to make it a reality. Its capacity to generate collagen with your own DNA fingerprint makes ch-OSA the genuine breakthrough in collagen.

    Nourish Your Body's 3 "Beauty Proteins" - Naturally!

    The condition of your skin, hair, and nails depends on three proteins:

    Collagen "plumps out" skin, removing wrinkles and preventing them from forming. In addition, collagen is essential for strong, healthy bones and joints.

    Keratin is the protein that's packed into your hair shaft. It gives your hair thickness, body, strength, and elasticity. Plus, keratin gives your nails strength.

    Elastin gives your skin its ability to stretch and "bounce back" preventing fine lines and wrinkles.

    With age, collagen keratin and elastin decline.

    BioSil Hair Skin Nails, with clinically proven ch-OSA, is specially formulated to help nourish your body's 3 beauty proteins and restore them to more youthful levels.

    I can really tell a difference when I take this supplement consistently. Hair and nails grow faster and I get new hair growth. Helped a lot when dealing with hair loss from hormones and thyroid.

    Thanks for your feedback!

    I always had very sensitive nails. They grew pretty fast, but broke even faster. I tried literally every nail strengthener to help my splitting nails, but nothing worked. Then I started using BioSil and I couldn't believe the effect it had. After the first month I noticed my nails stopped breaking almost entirely, they were stronger and more flexible. I have been taking it regularly for the past four months and my nails are absolutely beautiful. Long and strong, no more breakage and splitting. I could not be more satisfied with the results. I think I am going to continue taking BioSil FOREVER. :D

    Thanks for your feedback!
