Inverse psoriasis

Inverse psoriasis causes smooth, shiny patches of skin in areas where skin touches or rubs together, such as under the breasts, in the groin or in the armpits. The patches may look red, brown or purple, depending on your skin color. The skin may feel sore or itchy. Common triggers are infection, certain medicines, and skin cuts or scrapes.

Heat and moisture can worsen symptoms. Try these self-care tips for managing inverse psoriasis:

• Wear loose-fitting, lightweight clothing that allows air flow.
• Keep the affected skin as dry as possible. Pat with soft tissues or use a blow dryer on cool and low settings.
• Try to avoid getting hot and sweaty.

For mild inverse psoriasis, treatment often starts with steroid creams you can buy without a prescription. Your healthcare professional also may prescribe creams that contain vitamin D or medicines called calcineurin inhibitors that calm the immune system. If you have more serious symptoms, you may need light therapy, prescription steroid creams, or prescription medicines taken by mouth or given as a shot.
