So if anyone didn't know this, antiperspirant can have a rebound effect that makes you sweat more over time. And it is also responsible for the crusty stains on your t-shirt armpits. Regular deodorant won't do that.

When I switched to just regular deodorant my armpits stopped sweating so much after a few weeks, and then it was no longer an issue. And no more ruined shirts. Wish I had known this sooner in life.

[–] [email protected] 5 points 2 hours ago (1 children)

I've had none of those issues. I wonder what makes the difference between our armpits?

[–] [email protected] 6 points 1 hour ago

I'm going to make a wild guess and say we probably have different DNA. 😂

Yeah I dunno, it doesn't affect everyone like that obviously but I've told that to several people over the years and many of them were like "yep exactly" so it's not that uncommon. But my pits used to soak my shirt at work, at a fucking office job. It was gross. Once I stopped using antiperspirant after reading/hearing/finding a pro-tip (from where, I have forgotten), that issue completely went away.

Just doesn't seem to be compatible with certain body chemistry.

I read that as antidepressant

Antiperspirant gives me rashes

Antiperspirant gives me rashes

For many people, this goes away after a few uses

[–] [email protected] 4 points 4 hours ago (1 children)

Is it the antiperspirant that gives you rashes or all the fragrances and unnecessary junk many contain?

[–] [email protected] 2 points 3 hours ago (1 children)

I would assume it's the antiperspirant since I can use deodorant w/o it with no issue

[–] [email protected] 3 points 2 hours ago

Antiperspirants tend to use either aluminum or zinc as an active ingredient, both are known to cause skin irritation in some people.

[–] [email protected] 5 points 6 hours ago

I read it as that too!

[–] [email protected] 4 points 8 hours ago

So THATS what that smell is.....

[–] [email protected] 39 points 8 hours ago (2 children)

For anyone else curious about the why

Gel plugs (how antiperspirant works on your sweat glands) are finicky. They need a little bit of sweat in order to form—but not too much. Antiperspirant applied in the morning isn’t ideal, because people sweat more during waking hours, when they’re active. If the armpits are too sweaty in the hours after application, the product gets washed away before it can form the plugs. The body is cooler and calmer during sleep. For gel plugs to form, “baseline sweating is optimal at nighttime before bed,” Glaser told me. Nighttime application has been shown to increase the sweat-reduction ability of normal antiperspirant from 56 percent to 73 percent.

What kind of anti perspirant are you using? The one I have just stops the bacteria on my skin from making the smelly chemicals. At least, as far as I know

[–] [email protected] 3 points 6 hours ago

Huh. In the past couple of years I've switched from showering in the morning to go to the office, WFH and all, to showering at night after I get sweaty hitting the trails, kayaking, lawn work, whatever.

Never had a BO or sweat problem, but I'm going to try skipping it before I work out in the afternoon. Bet it makes no difference!

[–] [email protected] 17 points 8 hours ago (2 children)

Wait, but wouldn't I just wash it right off the next morning when I shower first thing? Well.....3rd thing. First I poop. Then I wait a half hour. THEN I shower.

[–] [email protected] 1 points 43 minutes ago

According to the article, it went wash off, but naturally dissolve after 24h

[–] [email protected] 12 points 8 hours ago (3 children)

Hard take that will expose me and a lot of people might not relate. But I shower at night before bed. I don't shower in the morning. Never smelled or anything. For those who shower after pooping, I'm an evening pooper as well. So, maybe there's something to this. Even with moderate sweat during the day, I never have body odor. It usually takes very heavy sweat from exercise or sports, or two days at least without a shower (very rare occurrence) for me to smell like anything.

[–] [email protected] 1 points 2 hours ago

A lot of it is body chemistry as well. For example sweat caused from stress smells worse than regular sweat. And then everyone's own chemistry is different on how their odor smells and how pungent how quickly.

[–] [email protected] 5 points 4 hours ago

Both of you need to get a bidet so you can decouple your pooping and showering schedules. Then your butthole can get a shower whenever it needs one.

Thank me later.

I also shower before bed, never really thought about it. I just always like to dispose of the day before going to bed.

I have experienced pretty much the same, regarding the next day and really only noticing when working out and sweating a lot.

I am also in the mood for exposing myself. I rarely use deodorant. I find it rather stinks much sooner and stronger with deodorant, than without.

[–] [email protected] 6 points 7 hours ago (3 children)

Man, I'm tired... I read that title as "deodorant works better if applied to the forehead"

[–] [email protected] 10 points 7 hours ago (1 children)
[–] [email protected] 8 points 7 hours ago

Apply directly to the forehead!

[–] [email protected] 1 points 5 hours ago

Well, we have been meaning to talk with you about your forehead odor.

I do this already simply because I shower at night and prefer to apply to clean skin. Always thought I was just a pretty unsweaty person. TIL

[–] [email protected] 3 points 7 hours ago
