My 2 year old kid has a scar from the insect bite what kind of cream can I put to get rid o the scar! F?

Improve, not rid. True scars are permanent so we hope for improvement, not erasure. Cocoa butter, vitamin E and Mederma have all been shown to be helpful when massaged vigorously, twice a day, into the scar. I hope this is helpful!
Insect bite scar. Insect bites do not usually leave scars. If it's still red from the bite, it's probably too early for the redness to disappear. Wait at least 3 to 4 weeks for the redness to be gone. Meanwhile, do nothing and wash with a mild soap.
