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] 10 points 4 days ago (1 children)

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

[–] [email protected] 9 points 4 days 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.

They're referring to the white buildup that happens from the aluminum in antiperspirant. Deodorant without aluminum (and therefore not an antiperspirant) won't give this buildup.

[–] [email protected] 0 points 4 days ago

I use Sure Men Invisible Ice Fresh. https://www.boots.com/sure-men-invisible-ice-fresh-antiperspirant-aerosol-200ml-10324663

It's an antiperspirant and contains aluminium, but doesn't leave any gross powder or stickiness, and my bf and I never get stains on our clothes. (I have experienced all of those things with other antiperspirants, so I'm not some sort of weird edge case).

Not trying to "um, actually" you, just wondering if you know what the difference is with this product. 😃

[–] [email protected] 2 points 4 days ago (3 children)

What's a regular deodorant? Also are there any solutions that don't involve the plastic container for it, I'm already on solid soap and shampoo for years but my deo still produces plastic waste.

[–] [email protected] 9 points 4 days ago

It won’t say antiperspirant on the label, it will just say deodorant, which means it doesn’t have any of the chemicals or metals they use to block your pores (or however it works, I’m not an antiperspirantologist)

[–] [email protected] 4 points 4 days ago

Try Nuud. It's made from sugarcane (except for the lid), and it's a great deodorant. It's a bit expensive but it does last a long time and functions really really well. I'm referring to the cream as I haven't tried the stick yet.

[–] [email protected] 2 points 4 days ago

Forgot to add, just search for plastic free deodorant, there are a bunch apparently!

I read that as antidepressant

Antiperspirant gives me rashes

[–] [email protected] 9 points 4 days ago (1 children)

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

[–] [email protected] 8 points 4 days ago (1 children)

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

[–] [email protected] 6 points 4 days ago (1 children)

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

[–] [email protected] 3 points 4 days ago

Oh I didnt know that about zinc. Zinc oxide is in a lot of stuff. Like diaper rash cream, sun screen, some exzema creams and dandruff shampoo. Must be a bitch to figure out what's causing your skin issues, especially if its in your skin care products.

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

I read it as that too!

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

Interesting! Are you allergic to aluminum?

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

I'm not sure. Maybe?

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

So THATS what that smell is.....

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

Antiperspirant gives me rashes

For many people, this goes away after a few uses

[–] [email protected] 6 points 4 days ago

When the skin falls off.

[–] [email protected] 53 points 5 days 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.

[–] [email protected] 7 points 5 days ago (1 children)

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] 12 points 4 days ago* (last edited 4 days ago)

To be fair though, most people with a BO problem don't know they have a BO problem because the human brain is incredibly good at simply throwing away at "constantly present" smells. That's also why people have a quasi unique scent, but they don't know what their own is.

I have definitely had a few coworkers with a BO problem that thought they didn't smell at all, so YMMV.

[–] [email protected] 2 points 4 days ago (1 children)

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 4 days ago (1 children)

That is deodorant antiperspirant actually prevents you from sweating in the first place

[–] [email protected] 2 points 4 days ago

Ohh, I confused them. Thank you for the clarification!

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] 18 points 5 days 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] 15 points 4 days 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.

[–] [email protected] 8 points 5 days ago* (last edited 5 days ago)

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] 3 points 4 days 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] 3 points 4 days ago

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

[–] [email protected] 11 points 5 days ago

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] 7 points 5 days ago (3 children)

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

[–] [email protected] 12 points 5 days ago (1 children)
[–] [email protected] 10 points 5 days ago

Apply directly to the forehead!

[–] [email protected] 3 points 5 days ago

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

[–] [email protected] 3 points 5 days ago

[–] [email protected] 2 points 5 days ago

Super interesting read, thank you!
