Deodorant Dilemma: Baking Soda and Sensitive Skin
Why does baking soda noticeably increase the efficacy of natural deodorant for some people and cause skin irritation for others? You have questions. We have answers! The Green Kiss uncovers the truth about baking soda.
The Science of Sodium Bicarbonate: Why Baking Soda Battles Body Odor When Added To Natural Deodorant
The alkaline properties of baking soda (sodium bicarbonate) aren't just helpful in making cupcakes light and fluffy. This versatile chemical compound is found all over the skincare industry, and for good reason. It's a natural antiseptic with antibacterial properties, and it packs a punch when used as a physical buffering agent (although we don't recommend it). To us, baking soda really earns its stripes for its ability to neutralize odour and absorb sweat when added to a natural deodorant. Unlike aluminum salts, which cozy up to sweat glands, clogging the pores and blocking the flow of sweat, preventing natural detoxification, baking soda tackles body odour by creating a pH environment that's too alkaline for odour-causing bacteria to thrive. Sadly, baking soda formulas are not a game changer for everyone. They can sometimes cause irritation, redness, or itching on the skin, especially for those with more sensitive skin types, hence the rise in baking soda-free deodorants.
Neutralizes pH: Sodium Bicarbonate helps neutralize the slightly acidic pH of sweat, creating an environment less conducive to the growth of odour-causing bacteria = controlling pit stink.
Absorbent Properties: Baking soda's absorbent nature helps soak up excess sweat, keeping the underarm area drier and reducing the wetness that can contribute to bacterial growth and odour.
Alkaline Nature: Sodium bicarbonate's alkalinity can help balance the skin's pH levels, reducing excessive sweating by creating an environment less favorable for sweat production.
Inhibits Bacterial Growth: Baking soda exhibits antibacterial properties that can inhibit the growth of odour-causing bacteria on the skin.

Possible Side Effects of Baking Soda in Deodorants
While baking soda is generally safe for most people, some of our clients experience unwelcome side effects. These can include:
Skin Irritation: Baking soda can be abrasive for sensitive skin, leading to redness, itching, or a rash. It's important to perform a patch test before regular use. (If you experience underarm irritation, the Rescue + Relief Spray from CV Skinlabs will soothe and calm the area.)
Dryness: Increasing your skin's pH can lead to dryness and disrupt your moisture barrier. Its moisture-absorbing properties can be particularly drying for those with dry or sensitive skin.
Discoloration: In some cases, baking soda may cause skin discoloration, particularly in individuals with darker skin tones. (There's a treatment for that.)
How To Get Rid Of A Deodorant Rash Fast
If you are experiencing side effects from baking soda in your natural deodorant, explore other options that do not contain baking soda but are still effective in controlling body odour. Then, build up your sodium bicarbonate tolerance by starting with a less concentrated regular strength formula. Experimenting with different formulations can help you find a natural deodorant that works effectively without causing irritation. Baking soda-free formulas not cutting it? The solution for tackling B.O. might already be in your skincare stash: an acid meant for your body. Repurpose your exfoliating acid to neutralize bacteria.
Our Takeaway
Baking soda is a powerful pH neutralizer and deodorizer that works well—for some of us! There's no apparent reason why irritation occurs in some people and not others. Some can use higher concentrations of baking soda without any problems, while others may develop a rash. Please note that underarm rashes are not always caused by baking soda; they may be caused by ingrown hairs, an unrelated allergy, or a sweat rash.
