Perioral Dermatitis Treatment
Perioral dermatitis is often very difficult to treat successfully. It usually requires several months of treatment. Recurrence of bumps is common, especially if you unknowingly apply skin creams containing steroids on your face or use any other products that are known to be aggravating factors.
Treatment options are targeted towards the underlying cause of the perioral dermatitis. If topical corticosteroids are being used, they should be stopped immediately. It is wise to stop using all cosmetics, makeups and skin care products for some time. Avoid using foundations with moisturizers as it can aggravate the condition.

However, moisturizer alone has no increase risk for POD. Always use mild soap-free cleansers and wash your face twice daily. Avoid using toothpaste containing fluoride or other products that contain chloride. For mild cases of perioral dermatitis topical antibiotics like metronidazole may be given. Other topical medications include clindamycin, erythromycin, azelaic acid, Benzoyl peroxide, Tacrolimus, Pimecrolimus, etc.
In case of moderate to severe disease, your doctor may prescribe combination therapy of topical medication with oral medications like oral doxycycline, tetracycline or minocycline for a course of 8-10 weeks. Patients with tetracycline allergy or children below 8 years and nursing mothers may be given oral erythromycin. Photodynamic therapy with topical 5-aminolevulinic acid has also shown some promising results in treating perioral dermatitis.
