Understanding Sensitive Skin: Why Typical Deodorants Cause Irritation
If your underarms get red, itchy, bumpy, or stingy after using deodorant—you’re not imagining it. Sensitive skin isn’t just a face problem. Your underarms are some of the most delicate skin on your body, and most deodorants just aren’t made with that in mind.
At MAGS Skin, we’ve seen firsthand how the wrong formula can lead to flare-ups, discomfort, and frustration. So let’s break down why most deodorants cause irritation—and what you can do instead.
Why Are Underarms So Sensitive?
Your underarms are warm, damp, and full of sweat glands and hair follicles. That makes them naturally prone to:
- Friction (from skin, fabric, and deodorant sticks)
- Bacterial overgrowth (hello, odor)
- Disrupted skin pH
- Trapped moisture
- Sensitivity from shaving, waxing, or exfoliating
Now add a product that contains baking soda, synthetic fragrance, or aluminum, and you’ve got a recipe for irritation.
Deodorant Irritation: What’s Really Going On?
Most irritation from deodorant comes down to one or more of these:
1. Disrupting Your Skin’s pH
Healthy skin has a natural pH around 4.5–5.5 (slightly acidic). This helps maintain your skin barrier and keeps harmful bacteria in check.
Baking soda, a common ingredient in natural deodorants, is extremely alkaline. It can throw off your pH and cause burning, peeling, or inflammation, especially after shaving.
2. Blocking Sweat Glands
Aluminum salts, used in antiperspirants, plug your sweat glands to prevent moisture. But that can lead to clogged pores, bumps, and tenderness, especially for sensitive skin types.
3. Irritating Additives
Artificial fragrance, alcohol, and preservatives can trigger allergic reactions or contact dermatitis, especially if you already struggle with eczema, psoriasis, or keratosis pilaris.
What to Look for in a Deodorant for Sensitive Skin
You don’t have to settle for stink or suffering. The best underarm care for sensitive skin involves:
- Fragrance-free formulas
- Baking soda-free and aluminum-free
- Spray format to avoid friction
- Soothing ingredients like aloe, magnesium, and chamomile
- Microbiome-friendly actives that support good bacteria
MAGS Skin checks all of these boxes. It’s designed specifically for sensitive skin, with a minimalist ingredient list, zero irritants, and real-world testing on people who actually struggle with flare-ups.

- Patch test new products before daily use
- Avoid applying immediately after shaving
- Switch to a spray formula to reduce friction and buildup
- Stick to fragrance-free products to reduce hidden chemical exposure
- Moisturize at night if you’re healing from a rash
Final Thoughts
If your skin feels angry after deodorant, it’s not just “your problem,” it’s the product. Deodorant should work with your body, not against it.
Understanding your skin’s needs, its pH balance, and how ingredients interact with delicate areas like your underarms can make all the difference.
