Using baking soda daily on underarms can cause irritation; it’s best to use it cautiously and not every day.
Understanding Baking Soda’s Role in Underarm Care
Baking soda, or sodium bicarbonate, is a popular household item known for its deodorizing and mild abrasive properties. Many people turn to it as a natural alternative to commercial deodorants because it helps neutralize odors by balancing pH levels and absorbing moisture. However, the skin under the arms is delicate and sensitive. Applying baking soda there daily raises important questions about safety, effectiveness, and potential side effects.
The alkaline nature of baking soda means it can disrupt the skin’s natural acidic barrier. This barrier plays a crucial role in protecting against bacteria, fungi, and irritants. When this balance is disturbed repeatedly—such as through daily application—skin dryness, redness, itching, and even rashes may occur. So while baking soda is effective at controlling odor initially, repeated exposure demands caution.
How Baking Soda Works on Underarms
Baking soda neutralizes acids that cause body odor by creating a less hospitable environment for bacteria. Sweat itself is odorless but when it interacts with bacteria on the skin surface, unpleasant smells develop. The alkaline pH of baking soda raises the skin’s pH from its normal 4.5–5.5 range closer to neutral or slightly alkaline (around 7–8), which inhibits bacterial growth temporarily.
Besides odor control, baking soda absorbs moisture well. This drying effect can reduce sweat accumulation and keep underarms feeling fresher longer. Its fine particles also provide gentle exfoliation that may help remove dead skin cells and unclog pores.
However, this disruption of the skin’s acid mantle comes with trade-offs if used excessively or without proper care.
Skin Sensitivity and Baking Soda
The underarm area contains thinner skin with many sweat glands and hair follicles. This makes it prone to irritation from harsh substances including alkaline products like baking soda.
Repeated use every day can lead to:
- Contact Dermatitis: Redness, swelling, itching due to inflammation.
- Dryness and Flakiness: Loss of moisture causes flaky patches.
- Burning Sensation: Especially after shaving or if applied on broken skin.
People with sensitive skin or allergies are more vulnerable to these side effects. Even those without prior issues may experience problems after prolonged daily use.
Scientific Insights: Is Daily Use Safe?
Scientific research on baking soda’s safety for daily topical use on underarms is limited but existing dermatological knowledge offers clues.
The skin’s acid mantle serves as a protective shield against pathogens and environmental damage.
Baking soda’s high alkalinity (pH ~9) contrasts sharply with this natural acidity (pH ~4.7). Frequent disruption weakens this defense mechanism.
A study published in The Journal of Clinical & Aesthetic Dermatology highlights that repeated exposure to alkaline substances can increase skin permeability and susceptibility to irritants.
This suggests that applying baking soda every day risks chronic irritation or even secondary infections if the skin barrier becomes compromised.
Baking Soda vs Commercial Deodorants
Commercial deodorants often contain ingredients designed to maintain the skin’s pH balance while controlling odor and sweat—such as aluminum compounds, antimicrobial agents, moisturizers, and soothing additives.
Baking soda lacks these supportive components. While natural and inexpensive, it doesn’t provide moisturizing benefits or barrier repair properties found in many formulated products.
Here’s a quick comparison table:
| Aspect | Baking Soda | Commercial Deodorant |
|---|---|---|
| pH Level | Alkaline (~9) | Balanced (around 4.5-6) |
| Main Function | Neutralizes odor & absorbs moisture | Controls odor & sweat; often moisturizes |
| Irritation Risk | Higher with daily use due to alkalinity | Lower; formulated for sensitive areas |
The Right Way To Use Baking Soda Underarms Safely
If you want to include baking soda in your underarm routine without risking irritation from daily application, consider these tips:
- Dilute It: Mix baking soda with water or aloe vera gel before applying to reduce alkalinity.
- Limit Frequency: Use no more than two or three times per week rather than every day.
- Avoid Broken Skin: Never apply immediately after shaving or on irritated areas.
- Add Moisturizers: Follow up with a gentle moisturizer like coconut oil or shea butter to restore hydration.
- Patch Test First: Apply a small amount on your inner arm before using regularly to check for reactions.
These precautions help maintain your skin’s health while still benefiting from baking soda’s deodorizing properties.
Baking Soda Alternatives for Daily Use
If you’re concerned about irritation but want natural options for everyday underarm care, several alternatives provide gentler solutions:
- Coconut Oil: Has antibacterial properties plus moisturizes skin deeply.
- Aloe Vera Gel: Soothes inflammation while offering mild antibacterial effects.
- Zinc Oxide Creams: Reduce odor-causing bacteria without harsh chemicals.
- Lemon Juice Diluted: Natural acid helps balance pH but must be used cautiously due to photosensitivity risks.
These options tend to be less abrasive while still helping reduce odor when used consistently.
The Impact of Skin Type on Baking Soda Use
Skin types vary widely—from oily and combination to dry and sensitive—and each reacts differently to topical products like baking soda.
Sensitive Skin:
People with sensitive skin should avoid daily use of baking soda altogether because their barrier function is easily disrupted. Even occasional use can trigger redness or itching.
Dry Skin:
If your underarms are dry naturally or become dry from shaving routines, frequent baking soda use will exacerbate flakiness and discomfort by stripping oils further.
Oily/Normal Skin:
Those with oilier underarms might tolerate occasional application better but should still avoid daily use due to cumulative irritation risks.
Understanding your own skin type helps tailor how often you can safely incorporate baking soda into your hygiene routine without adverse effects.

Frequently Asked Questions
Can I use baking soda for underarms every day without irritation?
Using baking soda daily on underarms can cause irritation such as redness, itching, and dryness. The skin’s natural acidic barrier may be disrupted by its alkaline nature, so daily use is generally not recommended to avoid these side effects.
How does baking soda work when applied to underarms every day?
Baking soda neutralizes odor-causing acids and absorbs moisture, helping to reduce sweat and bacteria temporarily. However, frequent daily use can disrupt the skin’s pH balance and damage its protective barrier, leading to sensitivity and discomfort.
Is it safe to apply baking soda on underarms every day after shaving?
Applying baking soda daily on freshly shaved underarms is not advisable. Shaving can cause micro-cuts or broken skin, making the area more prone to burning sensations and irritation from baking soda’s abrasive and alkaline properties.
What are the risks of using baking soda for underarms every day on sensitive skin?
People with sensitive skin risk developing contact dermatitis, dryness, and inflammation when applying baking soda daily. Prolonged exposure can worsen these symptoms, so it’s important to use it sparingly or consider gentler alternatives.
Can daily use of baking soda for underarms affect skin health long-term?
Long-term daily use of baking soda may impair the skin’s acid mantle, increasing vulnerability to bacteria and fungi. This disruption can lead to chronic dryness, irritation, and potential rashes if not used with caution or proper skincare routines.
The Role of Shaving in Baking Soda Sensitivity
Shaving thins the uppermost layer of the skin and creates tiny micro-abrasions that increase vulnerability. Applying an alkaline substance like baking soda immediately after shaving often leads to stinging sensations or inflammation.
To minimize discomfort:
- Avoid applying baking soda right after shaving; wait at least several hours until the skin calms down.
- If you shave frequently (daily or every other day), consider skipping baking soda entirely during those periods.
- If you do apply it post-shave accidentally, rinse thoroughly with cool water and apply a soothing moisturizer promptly.
- Dilute before application;
- Lather only two or three times per week;
- Avoid freshly shaved areas;
- Add moisturizing steps;
- Pursue gentler alternatives for everyday freshness.
This approach reduces cumulative damage caused by combined mechanical (shaving) and chemical (baking soda) stressors.
The Verdict: Can I Use Baking Soda For Underarms Every Day?
The straightforward answer is no—you shouldn’t use baking soda on your underarms every day if you want healthy, irritation-free skin long term. While it works wonders as an occasional deodorizer thanks to its alkalinity and absorbent qualities, repeated daily application disrupts your natural acid mantle too much.
This disruption leads to dryness, redness, itching, burning sensations, rashes—even infections if left unchecked. Sensitive individuals are especially prone to these issues but even those with tougher skin should limit frequency.
Instead of daily use:
Maintaining balance between efficacy and safety ensures your underarm care routine supports both comfort and hygiene without harm.
A Final Thought on Natural Underarm Care
Natural doesn’t always mean harmless—especially when applied frequently over delicate areas like underarms. Baking soda offers clear benefits but demands respect for its potency as an alkaline agent capable of disrupting fragile skin barriers if misused.
By understanding how it works chemically alongside your unique physiology—and adjusting usage accordingly—you can enjoy fresher-smelling days without sacrificing healthy glowing skin underneath your arms.
In summary: moderation beats overuse every time!
