hi,for the past few months i have been putting deodorandt on my crotch are to decrease the amount of sweat, and to eliminate the bad smell. for the first few months, it was very effective. however, after i changed from a creamy type of deodorant to a dry stick (old spice brands), i developed a rash that is very itchy and has now started to subtly peel from dryness. i put lotion on the area at the beggining of the day, but i still apply the deodorant and the rash is still persistant. my question is: why do i suddenly have this rash and what should i do about it, but in a way i could still eliminate the odor?Thank you in advance.
