Ok so collagen patches... are left over from my husbands knee surgery, I didn't know what they were till the doctor told me it was collagen. My first thought was, can I use this on my face and the answer is YES! This 7x7 sheet can be cut to any size. They tend to dissolve when moisture comes in contact so be careful as they will dissolve. his knee is all healed so I am offering up the extras.
