Quick answer
If your underarms react to aluminum or baking soda, a niacinamide deodorant like frank body's Niacinamide Deodorant can neutralize odor, absorb moisture, and smooth skin without irritation.
Why conventional deodorants cause irritation
Many deodorants and antiperspirants rely on aluminum salts to block sweat glands or baking soda to absorb moisture. For some people, these ingredients trigger redness, stinging, or bumpy rashes—especially after shaving or on sensitive skin.
Natural alternatives often swap aluminum for baking soda, but that can be just as harsh. A niacinamide deodorant offers a different approach: it traps odor at the source and controls wetness without relying on pore-clogging or alkaline ingredients.
How niacinamide deodorant works
Niacinamide (vitamin B3) is known for its barrier-strengthening and soothing properties in skincare. In a deodorant, it helps calm the underarm area while antioxidant-rich berry extracts and cyperus rotundus (a natural regrowth fighter) work to reduce odor and slow hair regrowth.
The formula uses neutralising actives that trap odour molecules rather than masking them with fragrance. Natural deodorisers absorb excess moisture, keeping your pits dry and fresh—without aluminum salts or baking soda.
Diagnosis: Is a niacinamide deodorant right for you?
- Symptom: Your underarms feel red, itchy, or sting after applying deodorant, especially after shaving or on hot days.
- Likely cause: Sensitivity to aluminum salts (common in antiperspirants) or baking soda (common in natural deodorants). Both can disrupt the skin barrier and cause contact irritation.
- Corrective action: Switch to a niacinamide deodorant. Apply a thin layer to clean, dry underarms once daily. The niacinamide soothes the skin while the neutralising actives trap odor and the natural deodorisers absorb moisture. If you have a known allergy to any ingredient in the formula, do not use this product.
- When to stop or choose another option: If irritation persists after 7 days of use, discontinue and consult a dermatologist. Niacinamide deodorant is not formulated for people who want to completely stop sweating—it manages moisture, not eliminates it.
