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.
