Uh my armpits are peeling?

I’ve started using a different deodorant. I’m using old spice men’s deodorant because my mom coupons and has a lifetime supply and I used it and realized that I like it better.

But I just.. my armpits are peeling dead skin like imagine a sunburn peeling. It doesn’t hurt at all but the peeling is insane. If I just rub my armpit skin comes off?

Has anyone else ever had this happen? I wash my armpits everyday in the shower.

Edit: lo and behold

I know I said it didn’t hurt but the reason I noticed it is Because I started sweating and my armpits started itching. I took a shower this morning and didn’t use it so I don’t have to wash it off but I let my pits air out and now they’re burning so that’s nice
