You Get BioSil ® Hair, Skin, Nails, the Advanced Collagen Generator®: “After the age of 21, we women lose about 1% of our collagen every year,” says Christie. Collagen is directly responsible for “plumping” skin, removing wrinkles, and creating vital skin elasticity. What’s more, collagen increases nutrient-rich blood flow to the scalp giving you thicker, stronger, and shinier hair. It makes your nails stronger too! That’s why Christie takes the clinically proven BioSil Hair, Skin, Nails every day. In her book, Christie says, “I am amazed at the results I see in my skin, hair, and nails.”
