Topical corticosteroids are among the most commonly prescribed treatments for psoriasis because they reduce inflammation, redness, and irritation, says Susan Massick, MD, an associate professor of dermatology at the Ohio State University in Columbus.
But if they’re used too frequently or for too long, they can cause skin atrophy, or thinning of the skin, says Dr. Massick.
Topical corticosteroid overuse can also lead to:
- Noticeable blood vessels (telangiectases)
- Hypopigmentation (light-colored skin)
- Easier bruising
- Delayed wound healing
- Acne breakouts
- Stretch marks (striae)
“This can happen with low-potency topical steroids when used for prolonged periods of time, or with higher-potency topical steroids when applied in more sensitive areas, such as the face, armpits, groin, or genitals, or if used for prolonged periods of time,” she says.
Massick recommends working with your medical provider to limit the length of treatment to short-term or intermittent use and avoid prolonged or continuous treatment times.
“Your dermatologist will tailor what type of topical steroid depending on how severe your disease is and what areas need to be treated, with lower-potency topical steroids reserved for the delicate areas of the face, armpits, breasts, and genital areas, and with higher-potency topical steroids more appropriately reserved for places like your arms, legs, hands, feet, and trunk — and not to be used on the face,” says Massick.
