In a clinical trial, fifty women aged between 40 and 65 with symptoms of aging skin were divided into two groups: one taking a placebo and the other taking 10 mg BioSil per day for a 20-week period. No other anti-aging treatment was followed. The results demonstrated that subjects taking BioSil experienced a 19% reduction in fine lines, wrinkles, and skin roughness. They also showed improved skin elasticity compared with those taking the placebo.
In another clinical trial the active ingredients of BioSil were shown to increase the diameter of each hair shaft significantly, adding fullness and body to the hair. Women participating reported that BioSil strengthened their nails, making them break resistant.
BioSil users often report that they notice the strengthening effect on nails in about 3 weeks. And by the second month of taking BioSil, they usually notice the thickening effect on their hair and smoothness on their skin.
