Perioral Dermatitis That Persists After Zero Therapy: What to Do Next

The first step in managing perioral dermatitis is elimination of all suspected topical products and cosmetics. When this approach fails to clear the skin, a structured next-line treatment is indicated.

Previous treatment — insufficient response

The initial line of management is zero (null) therapy: complete discontinuation of all topical products — cosmetics, soaps, detergents, moisturisers, abrasives, astringents, day/night creams, and skin conditioners — with the patient washing with mild water only. Local neutral preparations (e.g. chamomile compresses, physiologic solution) may be used, and any topical corticosteroids are gradually tapered.

Target of zero therapy: gradual disappearance of all symptoms and complete clearing of the facial skin as exogenous factors are removed.

When this goal is not achieved, escalation to the next protocol step is appropriate.

Next-step approach

The protocol at this stage introduces topical pharmacotherapy — a specific class of topical agents is applied to address residual disease. The full regimen and clinical algorithm, including which agents are used and how they are selected, are detailed in the structured protocol.
