Description

Inverse psoriasis appears as smooth, red, inflamed patches in skin folds, such as under the breasts, in the armpits, or around the groin, rather than the thick, scaly plaques seen elsewhere on the body. Friction and moisture in these areas often make it more irritated and sensitive than plaque psoriasis.

Causes

The same overactive immune response as other psoriasis types, worsened in skin folds by heat, moisture, and friction.

Prevention

Keeping skin folds clean and dry, and using breathable fabrics, can help reduce irritation and flares.

Treatment Options

Lower-potency topical steroids suited for sensitive skin folds, topical calcineurin inhibitors, and treating any secondary yeast or fungal infection.

Myths vs. Facts

Myth: A red rash in a skin fold is always a fungal infection. Fact: Inverse psoriasis is often mistaken for fungal infections, so an accurate diagnosis matters for choosing the right treatment.

When to See a Dermatologist

If a persistent red, smooth rash in a skin fold doesn't improve with antifungal cream.
