Perioral dermatitis first appeared on my chin during a humid Sydney summer, where it lingered as a ring of tiny red bumps and dry patches clustered around my mouth. I had been testing a heavier night cream at the time and layering rich serums, and within a fortnight the skin around my lower face felt tight, itchy, and unfamiliar. My first instinct was to treat it like hormonal acne, which only made things angrier, before a GP in Newtown confirmed what was actually happening.
The standard advice for perioral dermatitis is to simplify. Heavy moisturisers, occlusive balms, strong actives, and anything heavily perfumed tend to prolong the rash, while a stripped-back routine gives the barrier room to recover. After several flares over the past few years, I have built a routine that is genuinely minimal, easy to maintain, and stocked almost entirely from Australian chemists and beauty retailers.
Below is the routine I follow when a flare is active, plus the gentle additions I bring back once my skin settles. If you would like to ask anything about your own situation, my contact page is the easiest way to reach me.
Perioral dermatitis is a chronic inflammatory condition that usually clusters around the mouth, sometimes spreading to the nose or under the eyes. It can look similar to acne, contact dermatitis, or rosacea, which is why so many people end up treating it with the wrong products at first. The skin feels tight, sometimes itchy, and tends to worsen with weather changes, stress, or anything that disrupts barrier function.
One of the most common triggers is prolonged use of topical steroid creams, including mild hydrocortisone bought over the counter. These can feel soothing in the short term but often create a rebound flare when stopped, which is why GPs usually recommend tapering off rather than quitting cold. Thick moisturisers, occlusive oils, and rich balms can also aggravate the rash because they trap heat and bacteria against the skin surface. Strong actives such as high-strength retinoids, benzoyl peroxide, and abrasive scrubs prolong the irritation by stripping the lipids the barrier needs to function.
The goal during a flare is to keep the skin cool, hydrated, and free from potential triggers while it recalibrates, which is why a minimal routine is so effective. Fewer products also means fewer variables, which makes it easier to spot what is genuinely helping. When my routine contained ten steps, I had no idea which product was causing problems. With only a cleanser, moisturiser, and SPF, any new addition becomes obvious within a day or two, and the skin tells me quickly if something has to go.
During a flare I use a fragrance-free, low-pH cream or gel cleanser at night only, and rinse with lukewarm water in the morning. That single change reduced the tightness around my chin within a week, especially during the cold, windy weeks Melbourne tends to throw at us in August when the skin is already feeling raw from temperature swings.
A few Australian-friendly options I rotate include QV Face Gentle Cleanser, CeraVe Hydrating Cream to Foam Cleanser, and La Roche-Posay Toleriane. All are widely stocked at Chemist Warehouse and Priceline, which makes restocking straightforward when a tube runs out. If I happen to be near a Mecca store, Bioderma Sensibio Micellar Water is my go-to for a non-stripping first cleanse on nights when I have worn SPF or a tinted product.
The texture of the cleanser matters more than the brand. Anything that leaves my face feeling squeaky or tight is a clear sign that my barrier lipids have just been stripped away. A finish that feels clean but still soft, almost like the skin has a thin layer of comfort left behind, is what I am aiming for. I also avoid hot water, which feels soothing in the moment but tends to leave my face flushed and more reactive later in the day.
The hardest lesson was accepting that the thickest cream in my drawer was never going to fix a flare. Rich balms sat on my skin like a film, and the rash would worsen within a day. What works instead is a lightweight, barrier-supporting moisturiser applied in a thin layer, morning and night, while the bumps are active.
Ingredients I look for include ceramides, panthenol, squalane, and hyaluronic acid, which reinforce the lipid layer without suffocating the skin. Australian brands such as Rationale, Alpha-H, and Hey Bud all make formulations that lean towards barrier repair, and most are available online through Adore Beauty or in Mecca. A pea-sized amount is plenty for the entire face, and I tap it in rather than rubbing, which feels gentler on tender patches.
When my skin is particularly dry from Brisbane's winter air-con or a long flight, I add a single drop of squalane on top of my moisturiser at night. Squalane is lightweight, non-comedogenic, and rarely stings, which makes it a safe optional layer for reactive skin. I avoid richer plant oils during a flare, since ingredients like coconut and olive oil tend to aggravate the rash and prolong the recovery.
Sun protection is non-negotiable here, where the UV index regularly climbs past eleven in summer and stays punishing well into autumn. Perioral dermatitis can darken into post-inflammatory hyperpigmentation, which then takes months to fade, so daily SPF is part of managing the condition long-term. The challenge is finding a sunscreen that does not sting or pill over the rash.
Mineral filters sit most comfortably on my skin during a flare. Zinc oxide formulations tend to feel less irritating around the mouth and do not migrate into the eyes the way some chemical filters do. Ultra Violette's Lean Screen, Cancer Council Face Day Wear, and Mecca's mineral sunscreen all wear well, though I usually skip foundation while the rash is active to avoid extra product sitting on the skin.
Reapplication every two hours is the bit most of us skip, particularly when we are commuting between Brisbane offices or chasing kids around Adelaide parklands. I keep a powder SPF in my bag for touch-ups over makeup and a small mineral stick at my desk for a midday top-up. Australian sunscreen legislation requires broad-spectrum protection claims to be backed by testing, which is one less thing to worry about when reading a label.
Perioral dermatitis has a long list of potential triggers, and identifying mine took a proper audit of every product touching my face. Fluoride toothpaste was an early suspect, and switching to a fluoride-free option from Coles softened the irritation around my lip line within a month. Sodium lauryl sulphate in cleansers and toothpaste was another culprit, and silicones in primers and foundations were surprisingly problematic too.
Common culprits to audit when your skin flares:
I learnt the hard way during a flare in Perth, where I had layered a vitamin C serum over a sensitised barrier and ended up with raw, peeling patches around my chin for two weeks. If you are unsure where your triggers are hiding, simplify for a month and reintroduce one product at a time. This is the approach I take every spring in Sydney, when humidity spikes and my barrier tends to wobble before settling back down.
Once the active bumps calm down, I keep the routine minimal for at least another four weeks. This is when I cautiously reintroduce gentle actives, always starting at the lowest frequency. Niacinamide, azelaic acid, and a low-strength glycolic acid are my preferred entry points because they support barrier function and even out tone without overwhelming the skin.
I recently wrote about how I reintroduce glycolic acid once a week without irritation, which has been the trickiest active to bring back into rotation. The full walkthrough lives in my glycolic acid guide, but the short version is once a week, on a calm-skin night, with a thick moisturiser underneath.
My flare-time routine in four steps:
When the weather shifts or the UV index climbs, I adjust rather than rebuild the routine. In summer I reach for a more mattifying SPF and a lighter moisturiser. In winter, particularly during the cold snaps we get in Hobart and Canberra, I layer a richer cream over my barrier serum. The routine stays stripped-back, but it flexes with the seasons and the climate, which has made the biggest difference to how often I flare.
