Hi, I have a 10 year old son, almost 11. He is into the throes of adolescence and has already started to smell quite a bit. He takes regular showers and we are getting somewhere with using anti-perspirant/deodrant. Only recently, has he began to complain it stings under his arms. He is not holding it too close and using it correctly, he’s even tried a roll on but nothing seems to be working. He obviously doesn’t want to smell but each time he uses something he says it stings. We have got him sensitive skin ones too but that doesn’t appear to help either. The skin doesn’t look sore or red after use either. It’s just on application. Does anyone have any suggestions on brand/products to try to help him out? TIA.
