The Sensitivity Question: Natural Deodorant for Reactive Skin

Are natural deodorants causing you pain?

Good news! 

Your armpits aren't broken. Your deodorant is.

If you've tried natural deodorant and it felt like rubbing sandpaper on a sunburn, you didn't fail. You just used baking soda (otherwise known as bicarb). Which is great for cleaning ovens. Not great for skin that fights back.

Here's the thing nobody tells you: most natural deodorants are baking soda with essential oils sprayed on top. Baking soda is alkaline. Your skin is acidic. Put them together and your underarms throw a tantrum. They get red. They itch. They feel like someone set them on fire with good intentions.

Did you give up? Go back to aluminium? Feel like you failed at 'going natural'?

Cut yourself some slack... you didn't do anything wrong.

The formula failed you.

Why Baking Soda Doesn't Work for Sensitive Skin

Baking soda works by neutralising odour. It's alkaline, so it changes the pH of your skin, which kills the bacteria that creates smell. Sounds smart. Feels terrible if your skin is even slightly reactive.

Sensitive skin already has a compromised moisture barrier. Adding something that disrupts your pH is like poking a hole in a dam and hoping it holds. It doesn't. You get irritation, redness, sometimes actual rashes.

Brands know this. They also know baking soda is cheap. So they put it in everything and market it as "natural" like that solves the problem.

It doesn't.

The Magnesium Alternative

There's another way. 

Magnesium works differently. Instead of changing your skin's pH, it absorbs moisture and neutralises odour at a bacterial level. It does the same job baking soda does, but without the chemical warfare on your underarms.

The difference? Your skin stays happy.

Magnesium is also gentler. It doesn't sting. It doesn't make you want to claw at your armpits. It just works. In a quiet, competent way.

For sensitive skin, this is the difference between a solution and a problem dressed up as one.

What Sensitive Skin Actually Needs

If your underarms are reactive, here's what you're dealing with: inflammation. Moisture sensitivity. A skin barrier that's already working overtime.

You need a deodorant that:

✅  Doesn't disrupt pH
✅  Absorbs moisture without drying out
✅  Has minimal scent (fragrance is inflammatory)
✅  Actually works (no point being gentle if you stink)

Magnesium-based deodorant checks all four boxes.

All Viva La Body Natural Solid Deodorants have zero bicarb or synthetic fragrance. Just magnesium, coconut oil, shea butter, and essential oils. The underarm-friendly kind.

The Week-One Reality Check

If you've never used natural deodorant before, your first week might still feel weird. Not because something's wrong. Because your body is recalibrating.

For about seven days, you might sweat a bit more. Your skin might feel different. This isn't a "detox" (that's marketing nonsense). It's just your body realising that, hey, we can actually regulate temperature now instead of being chemically locked down.

By day eight, most people feel normal. By day 14, they feel better.

This applies whether you're sensitive or not. But if your skin is reactive, this adjustment period matters. You need a formula gentle enough to let your skin adjust without adding inflammation to the mix.

Baking soda makes this worse. Magnesium makes it neutral.

The Scent Question

If you've got reactive skin, fragrance is your second enemy (after baking soda).

Most "natural" deodorants use essential oils at concentrations high enough to actually smell strong. Which is great for trying to scent-bomb random strangers around you. Less great if your underarms are already complaining.

The Sensitive formula we make has literally no fragrance. It's unscented. You get the magnesium working without any added irritation.

Will It Actually Work?

Yes. But probably differently than you expect.

Antiperspirants prevent sweating. Natural deodorants let you sweat (which is fine) and neutralise the smell (which is the actual job).

So if you're used to being bone dry, natural deodorant might feel like you're sweating more. You're not. You're just noticing that your body is actually working.

For most people, magnesium deodorant is just as effective as anything else. For sensitive people, it's more effective because you're not fighting inflammation and deodorant at the same time.

You're literally just trying to not smell. Which is easier than you'd think when your skin isn't staging a rebellion.

The Test

Here's how you know if baking soda is your problem:

Apply any natural deodorant. Wait one minute. If your underarms feel hot, itchy, or irritated within five minutes, it's the baking soda. Your skin is telling you something.

If you feel nothing (or just the normal sensation of deodorant), you're fine with baking soda. Some people are. Their skin doesn't care. Lucky them.

If you're sensitive, a magnesium formula changes the game because there's no alkaline irritation happening in the background. You can actually focus on whether the deodorant works instead of whether your skin is about to stage a mutiny.
