When searching for Scar Treatment products, check the ingredients lists for Silicone/Dimethicone. This is the only ingredient documented to be effective on scars via scientific studies published in reputable medical journals. Other ingredients may be good for the skin, but when added to Scar Treatment products, they can actually decrease effectiveness.
I have used Scarfade over the past 14 years off and on for various cuts and even a couple surgeries. I had a horrible two inch cut on my ankle from shaving my leg and now, even 10 years later you can’t see where it was because I used Scarfade Scar Gel. It is important to use it twice a day and be diligent about using the gel until the scar is faded but it is worth it. I have also used Scarfade on my knee after arthroscopic surgery and you can’t see the incisions, the same with my shoulder. When I go in for my final shoulder surgery in March I will again use Scarfade to get rid of the incision marks.
