What should you know about over-the-counter care for perioral dermatitis?

Perioral dermatitis causes small red bumps, dryness, scaling, burning, or sensitivity around the mouth. It can also affect the nose or eyes, and the skin immediately next to the lip border may be relatively spared. The appearance can overlap with acne, contact irritation, rosacea, or infection, so a diagnosis cannot be made from bumps alone.

Common aggravating factors include topical corticosteroids, heavy occlusive products, fragranced cosmetics, and multiple active ingredients. Stopping a steroid may briefly make the rash look more inflamed before it settles; prescribed steroid use should be discussed with the clinician who advised it.

Use lukewarm water and a mild, fragrance-free cleanser, or simplify cleansing if even that stings. Pause scrubs, exfoliating acids, retinoids, essential oils, heavy balms, and fragranced makeup on the affected area. Choose a light, bland moisturiser only if needed, and avoid repeatedly touching or squeezing the bumps. Do not start an over-the-counter steroid cream for this rash. Take a product list to a pharmacist or clinician before adding an acne treatment.

Arrange medical assessment when the rash is spreading, involves the eyelids or eyes, keeps returning, or does not improve after simplifying products. Seek prompt care for eye pain, vision changes, marked swelling, pus, fever, or rapidly worsening redness. Prescription topical or oral treatment may be needed when gentle skin care is not enough.

Ask whether the bumps fit perioral dermatitis, which products or medicines may be contributing, and whether you should stop a steroid or another prescribed product. Ask how to protect sensitive skin, when to expect improvement, and whether topical antibiotic therapy or oral treatment is appropriate.
