Hello ..Thanks for your query.
The lesions you mention may be eczematous lesions.
These typically are more in dry skin
.Any contact irritant might make it flare up more, eg. soaps ,lotions ,clothes (synthetic).
You should visit a dermatologist
for a confirmatory diagnosis.This frequently requires long term management and life style changes to keep the flares under control.
Your daughter should take bath in luke-warm water with only mild soaps.She should be applied good emollients in adequate quantities several times in a day to keep the skin hydrated.
she has might require topical steroids
and should be best applied after advised by a dermatologist.
Hope this helps.Take care!
