Girls, could you please tell me after bathing such stains come out, then dry slightly disappear, but the mark is left, then after bathing again they become brighter, maybe an allergy on the bubhen? Or on water? We wash without anything in ordinary water from the tap with a product bubhen, or baby soap and still such stains come out. And please advise me a good allergist or dermatologist in Alma. Thank you in advance!
