When I was younger I masturbated which caused the skin on my penis to crack/injure. Over time (2+ years) it has healed, but has left me with a significant white patch of skin that's very noticable on my shaft. I would like to get rid of it. I'm guessing it's scar tissue so UV light wouldn't help, right? Any lotions or anything that would darken the skin to match the color of the surrounding skin? Thanks!
