I have keloids and so does my mom. My kids dont however. I had some on my ears and had them removed. A dermotologist can help, sometimes cortisone shots make them shrink and soften the scars. I havent found any over the counter products that help. Every time I get a cut is a potential keloid. Just means you got to be careful and no pierced ears ever. Hope this helps.
my kids have them too. my daughter had a real big keloid on her knee from some stitches she had to get and we got some vitamin E tablets, she rubbed that on the scar a couple times a day and the puffiness went down. My husband had to get one surgely removed from his ear and it kept coming back until he finally found a doctor who knew what he was doing. He shaved it off and then had him put this tape that had a steroid in it on his ear for about a year.
