Back to school deodorant

Mv

Ok mommy’s so my 10 year old daughter recently started using deodorant she says she feels stinky so I bought her the degree teen one after a while I started seeing rashes in her armpits I switched it to dove and it kept happening finally I tried lady speed stick it does the same thing too, do any of you recommend anything she can use if nothing works I’m going to be taking her to the doct to she what they tell me right now she’s not using anything and this is how her rash looks now it’s definitely better then when she uses deodorant
