Collagen is the building block of great skin. I have found the fountain of youth on EBAY. Yes, you heard right. A brand new product which makes my skin feel firm, soft and smooth. Made by Hanson biomedical labs this stuff is unbelievable. I'll try anything once, but was hesitant because the product is rather pricey. Definitely worth it! Hanson Avian Collagen is the greatest. I can't believe how wonderful my 52 year old face looks.
