When small, bumpy red spots appear around the mouth, applying layer after layer of cream on the assumption that “the barrier is damaged” is not always the answer. Perioral dermatitis is an inflammatory skin condition in which small papules cluster around the mouth, nose, and eyes; heavy cosmetics and facial steroids can be aggravating factors.[2][3] For an active flare, checking the cause and using medication appropriate to the diagnosis come before procedures.
In July 2025, Hailey Bieber spoke publicly about a worsening of her perioral dermatitis and shared a simple routine consisting of washing with water and using prescribed azelaic acid and clindamycin.[1] The key lesson is not to copy a particular product list. A rash in the same location may be acne, rosacea, or contact dermatitis, so the pattern should be distinguished before trying to name it.
How is perioral dermatitis different from acne around the mouth?
Perioral dermatitis often appears as small red papules and pustules clustered outside the lip line, leaving a narrow strip of normal skin immediately adjacent to the lips. It can also spread to the sides of the nose or around the eyes, so it is sometimes described as periorificial dermatitis, meaning dermatitis around the mouth, nose, and eyes.[2]
Comedones such as blackheads and whiteheads are clues to acne. Perioral dermatitis often has no obvious comedones and may be accompanied by stinging, tightness, and scaling. Rosacea is more likely to involve persistent redness and warmth on the nose and cheeks, along with visible small blood vessels. The conditions can overlap, so making a definitive judgment from a photograph alone can lead to the wrong treatment sequence.[3]
Why can applying more ‘gentle cream’ make it spread?
When the skin stings, it is natural to reach for a rich balm, oil, or sheet mask. But with perioral dermatitis, highly occlusive products can keep heat, moisture, and irritants against the skin for longer, allowing the rash to persist. Even a product labeled for “barrier repair” is not exempt if its texture is heavy.[2]
As the number of products increases, it also becomes harder to identify the cause. If the cleanser, toner, essence, oil, and cream are all changed at once and the skin does not improve, there is no way to tell which ingredient may be responsible. For this condition, a minimal routine is not giving up on skin care; it is a process that makes the diagnosis clearer.
Why are facial steroids an important clue?
Steroid ointments can quickly calm redness and itching, making the skin appear better at first. But with perioral dermatitis, their use can lead to dependence and a rebound flare after discontinuation. DermNet advises stopping topical steroids on the face; if a potent product has been used for a long time, it recommends tapering under medical guidance and avoiding restarting it because of rebound symptoms.[2]
This does not mean stopping essential steroids, such as nasal sprays or inhalers, on your own. Wash around the mouth and face after use, and tell your doctor where the rash is and when it began. Bringing the steroid name and duration of use can make it easier to establish a tapering plan.
What can we learn from Hailey Bieber’s routine—and what should we not copy?
The useful lesson is to simplify the routine during a flare and center it on prescribed medication.[1] What should not be copied are the medication names and sequence. Azelaic acid may be used to reduce inflammation, but it can cause stinging, while clindamycin is an antibiotic, so the diagnosis and duration of use need to be considered.
A celebrity’s improvement is not a diagnosis. Even a low-concentration acid, a low-irritation toner, or an antimicrobial mist can be irritating if the skin is currently cracked and burning. Rather than focusing on having “the same symptoms as a celebrity,” check three pieces of information on your own skin: whether comedones are present, the distribution around the lip line, and any history of steroid use.
How is medication selected?
For mild, localized cases, topical treatments such as metronidazole, erythromycin, or pimecrolimus may be considered.[2][3] Pimecrolimus is a calcineurin inhibitor that reduces inflammatory signals in a way different from steroids. It can cause burning, so it should not automatically be viewed as a “gentle alternative.”
For widespread or persistent cases, oral tetracycline antibiotics such as doxycycline may be considered.[2][3] In this setting, the goal includes reducing inflammation, not only providing an antibacterial effect. The possibility of pregnancy, age, and interactions with other medications must be checked, and leftover antibiotics should not be self-administered.
When can laser or skin boosters be considered?
During an active phase, when red papules are present and the skin stings, laser treatments, peels, radiofrequency microneedling, and skin boosters are not priorities. They can further irritate the skin barrier and make the recovery course harder to assess. First stabilize the inflammation; if residual redness or pigmentation truly persists, assess it as a separate issue.
Even if redness remains after treatment, observe natural recovery for several weeks rather than immediately scheduling a vascular laser. Repeating procedures while the perioral dermatitis is flaring again makes it difficult to distinguish the cause from a side effect. With this condition, deciding which procedures not to undergo is also an active part of the treatment plan.
How can you create a minimal routine at home?
In the morning, wash briefly with lukewarm water or a low-irritation cleanser, then use only a light, minimally fragranced moisturizer and a sunscreen you can tolerate, such as a mineral sunscreen. Repeat the same cleansing and moisturizing routine in the evening. Take a break from scrubs, exfoliating toners, retinoids, high-concentration vitamin C, and sheet masks until the rash settles.
Add only one new product at a time, leaving an interval of five to seven days. Photograph the rash every other day in the same lighting, and record pain, stinging, and its extent. If blisters, yellow crusts, eye pain, or rapid swelling develop, do not wait assuming it is simple perioral dermatitis; arrange medical care sooner.
Frequently asked questions
If fluoride in toothpaste is the cause, should I switch to fluoride-free toothpaste?
There is not sufficient evidence that fluoride toothpaste is the cause of all perioral dermatitis. Rinse so toothpaste foam does not remain around the mouth, and if irritation from fragrance or surfactants is suspected, change only one variable and observe the course. Do not make an arbitrary switch at the expense of cavity prevention.
How quickly does it improve?
Even after reducing the products that may be responsible, redness can worsen from rebound over the course of several days, and treatment response may take weeks.[2] For this reason, it is better to maintain the prescribed plan and photographic record than to change products day by day.
Dr. Kang Jeong-ha’s recommendations
First, starting today, stop exfoliants, retinoids, strongly fragranced products, and heavy balms, leaving only three steps: cleansing, light moisturizing, and sunscreen. Second, write down the names and durations of any facial steroids and steroids used for rhinitis or asthma, and show them at your appointment. Do not stop prescribed steroids on your own; confirm whether tapering is appropriate.
The first priority in treatment is an accurate diagnosis. For a localized rash, choose metronidazole, erythromycin, or pimecrolimus according to the symptoms and the potential for irritation. If the area is extensive or the condition keeps recurring, consider oral doxycycline next.[2][3] The expected benefits are a reduction in inflammatory papules and stinging, while risks such as burning, gastrointestinal discomfort, and medication contraindications should also be reviewed.
Defer laser treatments, peels, radiofrequency microneedling, and skin boosters during the active phase. Consider them only after the rash has sufficiently settled and residual redness or pigmentation remains stable, following a separate assessment. In daily life, prioritize not touching the skin, adding only one new cosmetic product at a time, and taking progress photos in the same lighting.
