Do Keloid scars get better after Sun exposure?
No, the sun is not good for keloids. It can take 1 to 2 years before you know what a scar will finally look like maybe this is what happened to you and being in the sun was just a coincidence. If you want to try and shrink the size of the scar you could use a product like Mederma, but be careful of exposing it to too much sun.
