I hope it's not keratosis pilaris. That's what my son has. At first he was diagnosed with eczema, but eczema is different, it's more dry, patchy spots. With KP, there are bumps that look like and feel like goosebumps, and the skin is red/pink. It is most common on the cheeks, arms, and legs. My son has it on all three. Poor guy. I was told after I took him to a dermatologist that he would most likely outgrow it on his cheeks, but that his arms and legs would most likely stay with him. The reason I say I hope it's not what it is is because there is no cure or treatment. I've tried EVERYTHING! The only thing I found that only KINDA worked was from dermadoctor.com, but my son started complaining about it "stinging", so I stopped using it after that. I was bummed because it really seemed to have made his skin a lot smoother. I figured I'll try it maybe again this year because he's 5 now, and I was using it back when he was 3, so maybe his skin was just too sensitive. Look it up on the internet and see if the rash like look of it is similar to your daughter's. I wouldn't waste money on a dermatologist if you find it's what it is. Sometimes someone will find something that works for them for awhile, but that's about as far as the treatment goes. Exfoliating is supposed to help too.
