I'm kind of a sweaty guy so I got miradry in my arm pits. They lasered out something like 80% of my sweat glands under my arms and it makes a big difference. I don't sit somewhere feeling absolutely disgusting worried that I stink. You can do it for your hands too if you have sweaty palms. Cost me like $2000.
I'm going to start some hair treatments here soon because it's getting thinner than I like up top
But my body still needs to cool itself so I now sweat profusely on my chest, back, forehead, and palms.
Do you find that your perspiration just found a different outlet?
Otoh, there are definitely people around that stink but are not visibly sweaty. I think it must be more a microbiome issue than anything volume related.
For the record, you are not the judge of your own odor.
And even if someone else says you have no body odor, that still doesn't mean you don't -- some people have less sensitive noses, some think "smell I'm accustomed to" = "no smell", and some will just try to be polite.
(Personally, I haven't put on deodorant since COVID started, but I'm pretty remote..)
