Underarm Psoriasis and Deodorant: What Actually Works

If you’ve ever tried to apply deodorant to a psoriasis flare under your arm, you know how painful it can be. Redness, itching, stinging. Sometimes it’s easier to skip deodorant completely than risk making things worse. But that’s not a long-term solution.

Here’s what to know about managing underarm psoriasis (also called inverse psoriasis) and why the right deodorant makes all the difference.

What Is Underarm Psoriasis?

Inverse psoriasis is a type of psoriasis that affects skin folds, like your underarms, groin, and beneath the breasts. Unlike plaque psoriasis, which causes thick, scaly patches, inverse psoriasis appears as smooth, red, shiny skin that often feels tender, raw, or sore.

Because it shows up in moist areas with constant movement and friction, underarm psoriasis is easily aggravated by things like:

  • Tight clothing
  • Shaving
  • Sweat buildup
  • And yes, most deodorants

Why Most Deodorants Make Psoriasis Worse

Many conventional deodorants and antiperspirants contain ingredients that disrupt your skin barrier, especially when your skin is already inflamed. These include:

  • Fragrance: One of the most common irritants for people with psoriasis
  • Alcohol: Dries out and stings compromised skin
  • Aluminum compounds: Used in antiperspirants to block sweat, but can trigger irritation or allergic reactions
  • Baking soda: A high pH ingredient that can throw off your skin’s natural balance

For someone with underarm psoriasis, these ingredients can lead to burning, flaking, or worsening inflammation.

Tips for Caring for Underarm Psoriasis

In addition to switching to a psoriasis-friendly deodorant, try these skin care tips:

  • Gently cleanse your underarms daily with a non-irritating soap
  • Avoid shaving during flare-ups, or use an electric trimmer to reduce friction
  • Keep the area dry and cool whenever possible
  • Moisturize after showering to prevent cracking or dryness
  • Use topical treatments as prescribed by your dermatologist

You don’t have to choose between comfort and confidence.

If you’re dealing with inverse psoriasis flares under your arms, the key is choosing products that support your skin, not fight against it.
