6 Tips to Gently Treat Psoriasis on Sensitive Body Parts

It’s possible to get psoriasis on any part of the body, but some areas are a little harder to treat than others. Sensitive areas of the skin, for instance, where the skin is thinner or where two skin surfaces are in contact with each other, tend to require different treatments or application methods.

“It’s really a question of absorption,” says board-certified dermatologist Sandy Skotnicki, M.D., an assistant professor in the department of dermatology at the University of Toronto. “The skin is thinner in certain areas, like the groin, the genitals, the face and the eyelids, so topical treatments are more readily absorbed.”

Other sensitive body parts are those with skin folds, such as the armpits, between the buttocks and under the breasts. These areas are sensitive because the skin is typically touching, which increases absorption and irritation due to sweat, Skotnicki says. Inverse psoriasis (also known as intertriginous psoriasis or flexural psoriasis), which presents as very red, smooth, shiny lesions, is most common in these areas.
