Inverse psoriasis is common in overweight people. This type of psoriasis appears in skin folds, such as the armpits, under the breasts, the groin, the folds around genitals and between the buttocks. The skin appears shiny and smooth with red, well-defined borders. The affected skin may also crack open and bleed.

Inverse psoriasis is sometimes mistaken for other skin problems, such as yeast or fungal infections. Because skin rubs on skin or clothing, chaffing, sweating and irritation can lead to these other infections. Inverse psoriasis can be confused with Candida.

Topical medications, such as corticosteroid creams and ointments (hydrocortisone), are usually prescribed first by your medical practitioner. These creams have anti-inflammatory properties. Another cream, such as Calcipotriene, a synthetic vitamin D compound, slows the production of skin cells and reduces inflammation. These two drugs used for eczema may help. Pimecrolimus cream and Tacrolimus ointment can only be prescribed for short term use due to an increased cancer risk. Your doctor may also prescribe Castellani Paint. This “paint” causes the moist areas to dry up and heal. Unscented powders can also help keep the irritated skin dry.

Always apply medications as directed. Overuse of corticosteroid creams can cause thinning skin and make your psoriasis worse. Do not cover damaged skin with a bandage, as moisture will be trapped, possibly causing a secondary infection. These medications can cause worsening irritation. Contact your doctor if this happens.
