Perioral Dermatitis Triggers
Perioral dermatitis is almost always driven by external triggers — specific ingredients in your skincare, toothpaste, or makeup. Identifying and removing those triggers is the first and most important step in clearing PD.

The single most reported PD trigger. Found in most cleansers, shampoos, body washes, and many toothpastes. Even some 'sensitive skin' products still contain SLS.
A top trigger specifically for breakouts around the mouth and chin. Many people see dramatic improvement within 2–4 weeks of switching to fluoride-free toothpaste.
Fragrance is a catch-all term for hundreds of potential irritants. The r/PerioralDermatitis wiki explicitly recommends stopping all fragranced products during PD treatment.
Heavy occlusives that trap bacteria on the skin surface and prevent the skin from breathing. Many people find their PD improves significantly after eliminating petroleum-based products.
Found in most conventional toothpastes and some skincare. A common trigger especially for perioral breakouts. Switching to mint-free toothpaste is often recommended alongside SLS-free.
An extremely common allergen and PD trigger found in lip balms, thick moisturizers, and nipple creams. Often listed as 'wool wax' or 'lanolin alcohol' on labels.
Steroid creams make PD significantly worse in the long run — even though they can temporarily suppress symptoms. Stopping steroids is usually a prerequisite for recovery.
Both are high-comedogenic, heavy occlusives that feed Malassezia yeast. Often marketed as 'natural' alternatives but widely reported as PD triggers.
These synthetic esters are highly comedogenic and can feed the conditions that worsen PD. Common in anti-aging creams and some makeup.
Oils high in oleic acid (olive oil, argan oil) disrupt the skin barrier and feed Malassezia. Often found in 'skin barrier repair' products that can paradoxically worsen PD.
