If you have inverse psoriasis, you know it affects sensitive areas of the body that are usually covered by clothing, and that it can be uncomfortable and keep reoccurring.

“Inverse psoriasis usually happens in areas of skin folds like the underarm, groin, and under the breasts,” says Julie Russak, M.D., a board-certified dermatologist practicing in New York City. “In these areas, you have a lot skin-on-skin contact, so the skin becomes macerated, or sweaty, and moisture typically occurs.” That moisture and chronic rubbing can cause psoriasis to flare, which can cause discomfort just about anywhere, but can really be an issue beneath the bra line.

Interestingly, according to Michele Koo, M.D., a board-certified plastic surgeon in St. Louis, Missouri who founded the skincare line Private Practice by Dr. Koo, this type of psoriasis is strictly caused by the “mechanical abrasion of skin against skin,” and if you follow the proper steps, you can prevent flares and feel more comfortable.
