Who doesn’t want a deodorant that actually works, yet deodorant pH is important too. In this post, learn why deodorant pH matters to keep skin healthy AND odor free.

Why pH Matters to Your Skin

You’ve probably heard of pH before, but why is it significant when it comes to your skin? To get a bit sciency, pH stands for ‘potential to free hydrogen ions’ and measures how acidic or alkaline a solution is. The pH scale goes from 0 to 14, with a pH of 7 considered neutral. High pH (above 7) is alkaline and low pH (below 7) is acidic. You can read more about skin and pH in a previous post here.

pH is relevant to skin because the skin’s surface is covered by a thin, protective layer called the acid mantle. The acid mantle is made up of fatty acids combined with lactic acid and amino acids and sits at a pH around 4.5 – 5.5. A healthy acid mantle helps to keep potentially dangerous irritants out (like bacteria) and moisture in. It also activates certain enzymes that are necessary for skin health. A damaged acid mantle leaves the skin susceptible to injury.

This is the Ideal Deodorant pH


Highly alkaline (high pH) ingredients disrupt the skin’s acid mantle, strip away its natural oils and kill bacteria that help keep our skin healthy. This includes cleansers with stripping agents (like sodium lauryl sulfate) and deodorants that contain ingredients like baking soda or magnesium hydroxide. With a pH around 8-10, these products can lead to skin dryness and irritation over time. They may also contribute to conditions including eczema, psoriasis and rosacea. At Apothekari, your wellness matters. We formulate products that are both safe and effective so you won’t find baking soda, magnesium hydroxide or harsh cleaning agents in any of our formulations.

A deodorant pH of around 4 – 6 makes most sense when it comes to your skin’s health. Formulated with odor neutralizing enzymes and lactic acid, Apothekari’s natural deodorants are in that pH range. They are formulated without baking soda, aluminum and parabens and your skin’ pH will not be disrupted. Get ready to smell fresh and feel clean all day, with the healthiest natural deodorant!

What to Do When Your Deodorant Irritates Your Armpits

If you’re using a natural deodorant and you develop skin irritation including redness, dryness, irritation or a rash, the formulation may be to blame. Some individuals react immediately, while others are fine until a few months down the road. One of many ingredients may be the cause, with baking soda or magnesium hydroxide right at the top of the list. Both are highly alkaline and can alter skin’s pH taking it out of its comfort zone. Baking soda rashes are VERY common (do a search on the internet). Other ingredients that may be problematic include coconut oil (blocks pores) along with essential oils.

If you end up with irritated armpits after trying a natural deodorant, no need to panic. Reactions usually go away on their own after a few days once you stop using the product. You can try applying cool compresses as well. Depending on how bad your reaction is, consider seeing a doctor. This may sound like overkill, but if the reaction sticks around for more than a few days, you may require medical attention.

My Fave Four Apothekari products

The first product I purchased from Apothekari was the A for Anti Aging. I have Never been able to tolerate retinol products and always ended up bailing because of dry flaky skin. Until A for Anti Aging. It's Amazing! I have now added the Vitamin C, the Deodorant (Neroli Rose is my current favourite but the Lavender is great too), and most recently the More than Lip Service (thank you thank you thank you Apothekari :)). While deodorant and vaginal moisturizer may sound like odd gifts, these are my latest go-to's for the gal who has everything. All have become fans!

THIS WORKS! No odour for 24+ hours including a yoga session!

I'm blown away by how effective this is, and by how clean and well thought out the formula is. I'm not used to roll-on so that took a couple days to adjust to, but its so much more effective than the solids/creams i was using that it is totally worth it. I'm converted - and i think i have probably tried 90% of the natural deodorants out there over the last 10 years LOL. thank you for creating this.

I love this body oil!

This is so luxurious and moisturizing (i have dry, sensitive skin and most oils don't do the trick) and also miraculously absorbs very quickly. And the lemon rose scent is just transporting - i look forward to using this after my shower.

Bespoke Vitamin C Serum

I love it! Been using it for years. It’s so perfect to put on right after I wash in the morning. I’ve never been the greatest at sticking to a skin care routine but using the Vitamin C in the morning and A is for Anti-aging at night consistently over the years has kept my skin young and firm.
Would not want to imagine life (or my skin) without these two essentials. Thank you Sharmani!

*Received as press sample*

Pricing per bottle is definitely up there, but I think much like skincare, if you have struggled to find a deodorant that works for you, the price won't be as much of an issue because something like this can have a huge impact on your life. One bottle should last about 3-4 months with daily use which I think is fairly close to most deodorants. While I know there are baking soda-free options (baking soda can cause skin irritations due to pH disruptions) and options that use Deoplex, I have yet to find a combination of Deoplex and lactic acid which may be what's working for me. Honestly, the only thing I didn't enjoy was that "wet" feeling when I would first apply it, but after 15 seconds it dries down AND it doesn't stain clothing so that's a huge plus. Even though I received this as a press sample, I would buy this deodorant on my own as I didn't just smell good at the end of a long day, but I smelled like absolutely NOTHING which is WAY better to me than smelling like "I'm covering something up" or like body odour. I also trust and appreciate the research I know Apothekari has invested into making sure the formulation is scientifically sound so I know that's also partly where my dollars are going. I only need to apply once a day and I'm good to go so one bottle might even last more more than 4 months at the rate I'm going! HIGHLY recommend and even though all three scents had the same results, my preferred scent was the Lavender as it just one of my favourite scents overall!
