My daughter and I have a skin issue. Deodorant usually will irritate our skin so, we have to be very cautious of the type and kind we have buy. Before my daughter used the deodorant, she had a flare up. Two days after using, she asked if I could see where she still had a flare up and I told her No! We have had for about 3 weeks now and we are doing great! I will forever use this product!
