BioSil Hair Skin Nails restores your body's three main beauty proteins. The condition of your skin, hair and nails depends on three proteins: collagen, keratin and elastin. Collagen maintains skin moisture and firmness, along with promoting healthy bones and joints. Keratin strengthens hair and nails and promotes hair thickness. Elastin supports your skin's ability to stretch and bounce back. As you age, the body's natural levels of these proteins decline. BioSil Hair Skin Nails, with ch-OSA Advanced Collagen Generator, promotes beauty nourishment.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

BioSil Orthosilicic Acid is rated 4.7 out of 5 by 10.
Rated 5 out of 5 by from Great product So I was skeptical at first. A product that helps restore skins elasticity and more. Peri menopause is no fun, and this is the only addition in the form of a supplement that I tried. Sure enough, the dryness, and elasticity improved. I was truly shocked and pleasantly surprised. I have since re-ordered and would recommend this to others. I did research the company and product before purchasing and read many reviews. I am happy to say that it works for me.

Rated 5 out of 5 by from Good Results I have been taking this supplement for a month and I believe I am seeing some good results with my skin. Too early to know what effect it is having on my hair. I will continue using it as long as I can afford it and as long I think it is beneficial.

Rated 5 out of 5 by from Great Product I take 2 capsules a day. My hair and nails grow like crazy since I've started taking this product about 6 months ago. And now that I'm writing this review, I've noticed my skin tone/complexion are also better! Hope it's having the same affect on my bones.
