My daughter is 3 years and 4 months old. She has extreme dry skin. I apply cetaphil restoraderm lotion 3-4 times a day. But in case of mosquito bites, she keeps on scratching the place for 15-20 days continuesly . Like she scratches and blood oozes out. I apply cream then a black layer appears and she scratches it again and again. This leaves so many marks on her body. Please guide as to what should i do so immediately in case of mosquito bites so that she doesn’t scratch it the first time and what should I apply on the marks to ligthen them??
