I don’t have the skin type for keloids but had a 3 inch one after a back surgery. I ran a microneedler (picked up from Amazon) very gently over it just once and two weeks later, it was GONE. I had a very noticeable burn on my upper thigh and used it several times and now you can’t see anything but a very faint pink where the 2nd degree burn scar was.
My daughter had huge keloids on her ears. Took her to a dermis who micro needled her they disappeared and never returned afaik
