Ah yes, fair pont. I didn't mean it in literal burns; more like smell so intense, you can still smell it even if you're away from the source, just by breathing. OH! just like when staring right into very bright light and for a moment you see a dark spot. And off of which both are really bothering to me

I've had antiperspirant fuck up my armpit hair. They were white with a weird texture for a year. I stick to deodorant now

you can definitely slightly hurt yourself with antiperspirants, just because sweat exists for a reason. When it's 40°C you need every single drop of sweat your body can muster to avoid heat stroke.
Thankfully deoderants without antiperspirant exists.
