I had knee surgery (Arthroscopic) last November 2015 so I went to see physical therapy and asked her how to solve the scars. She said to me that go buy Vitamin E Skin Oil so I did it and put it on my scars and rubbed it to let it absorbs. I do it every morning and every night. It went very well and my scars healed fast but still work on it every day. The product is excellent!!
