Perioral Dermatitis Treatment
Perioral dermatitis (PD) is a common inflammatory skin condition that causes a rash of small red bumps around the mouth, nose, and sometimes eyes. It affects people of all ages, though it is more common in women.
The good news: most PD is driven by external triggers — specific ingredients in everyday products. Identifying and removing those triggers often clears PD without medication.
Treatment approaches
Remove known triggers first
This is the most important step and should be done before anything else. The most common culprits are SLS in cleansers, fluoride and mint in toothpaste, fragrance in any product, heavy occlusives like petrolatum and mineral oil, and topical steroids.
Zero therapy
Zero therapy means stopping all topical products on the affected area and letting the skin reset. It is one of the most consistently reported approaches in the PD community. There is typically an initial flare before improvement begins around week 4.
Zero therapy guide →Hypochlorous acid
Hypochlorous acid (HOCl) spray is one of the few products widely recommended even during zero therapy. It is antibacterial, anti-inflammatory, and disrupts biofilms linked to PD. Spraying it 3–5 times daily on affected areas is a common approach. Look for products like Tower28 SOS or similar HOCl-based sprays.
Azelaic acid
Azelaic acid (15–20%) is considered safe for PD and can actively help reduce inflammation and bacterial load. Unlike many other actives, it is generally well-tolerated even on sensitive perioral skin. Start with a low percentage and apply a small amount every other day to start.
Oral antibiotics (medical)
When lifestyle changes do not fully resolve PD, a dermatologist may prescribe a course of oral antibiotics — typically doxycycline (50–100mg) for 6–12 weeks, or oral tetracycline. These work systemically and do not require topical application to the affected area. Oral antibiotics are considered more effective and safer for PD than topical antibiotics.
What NOT to do
- ⛔Do not use topical steroids. Hydrocortisone and other steroid creams cause temporary suppression followed by severe rebound flares. They are widely considered the #1 cause of steroid-induced PD.
- ⛔Do not add more products.Adding essential oils, “natural” remedies, or multiple new products at once makes it impossible to identify your trigger.
- ⛔Do not use retinoids on active PD. Retinol and prescription retinoids can aggravate active breakouts around the perioral area.
