Perioral Dermatitis — Conditions

What is Perioral Dermatitis?

A chronic skin condition characterized by small papules and redness around the mouth

Steroid overuse, fluoride toothpaste, and cosmetics can be contributing factors, with characteristic small rashes appearing around the mouth and sides of the nose.

Caution

Stop using steroid creams immediately and consult a dermatologist.

Main causes & characteristics

Perioral dermatitis, characterized by small papules and redness around the mouth, is known to be most commonly associated with prolonged misuse of topical corticosteroids. Fluoride toothpastes, heavily fragranced cosmetics, and occlusive moisturizers may irritate the skin around the mouth and sides of the nose, potentially triggering a rash. Hormonal changes and frequent mask wearing are also cited as contributing factors.

How to manage

Discontinuing topical corticosteroids and irritating products that may be responsible for the condition and simplifying the skincare routine is recommended. Using a gentle, low-irritant cleanser and a light moisturizer may help, though improvement can take time. Consulting a dermatologist is recommended regarding whether to discontinue corticosteroid use, and if the rash recurs or spreads.

Good to know alongside

Perioral dermatitis is recognized as a facial rash condition often discussed alongside rosacea, seborrheic dermatitis, and steroid-dependent dermatitis as conditions requiring differentiation.

Everyday care tips

Switching to a toothpaste with lower fluoride and foaming agent content and applying only a thin layer of a fragrance-free, simple moisturizer around the mouth area may be helpful.
