Maskne: How to Prevent and Treat Mask Acne

Maskne is acne caused or worsened by wearing a face mask. Breath and sweat make the skin under it warm and humid while the mask rubs and presses, which clogs and inflames follicles. To prevent it, wear a clean, well-fitting mask with a soft cotton inner layer, wash with a mild cleanser after long wear, use a light non-comedogenic moisturizer, and take short mask breaks when it's safe.

Below is who still deals with maskne, why the skin under a mask behaves the way it does, how to pick and wash masks, a short routine that protects your skin barrier, and how to tell maskne from look-alikes such as perioral dermatitis and rosacea.

Who still gets maskne?

Anyone who wears a mask for hours at a time can get maskne, and that group is larger than the end of pandemic mandates suggests. DermNet notes that mask symptoms are more commonly reported when a mask is worn for more than 4 hours a day, so the people most affected are the ones who mask for whole shifts or long stretches:

• Healthcare workers. In a survey of 542 frontline doctors and nurses in Hubei, China, 97% reported skin damage from protective equipment, most often on the bridge of the nose (83%), with the cheeks, hands and forehead also affected, and wearing an N95 for more than 6 hours a day roughly doubled the odds of damage at the mask sites.
• Commuters and travelers who mask on crowded trains, buses and flights, often for an hour or more each way.
• People with allergies, asthma or a weakened immune system who mask during pollen season, respiratory-virus season or around crowds.
• Workers in dusty or food-handling jobs where a mask is part of the uniform.

The scale is real. A 2022 systematic review and meta-analysis of 37 studies and 29,557 participants found facial skin problems in 55% of mask wearers, with acne in 31%. How long the mask stayed on was the strongest risk factor. DermNet adds that people who already have acne, rosacea, seborrheic dermatitis or atopic dermatitis are at higher risk.

Why does wearing a mask cause acne?

A mask creates a small, closed climate on your face, and that climate is hard on follicles. DermNet describes maskne as a form of acne mechanica, the type of acne set off by heat, pressure and friction. Four things happen at once under the fabric:

1. Humidity and heat. Every breath warms and wets the air trapped against your skin. DermNet links the rise in humidity and temperature from breathing in a closed space to a weaker skin barrier, blocked follicles and more oil.
2. Occlusion. Sweat, oil and any product you applied can't evaporate, so they sit on the skin for hours.
3. Friction and pressure. The edges of the mask and the nose wire rub with every word and head turn.
4. A shifted skin microbiome. A review in the Indian Journal of Dermatology describes maskne as an interaction of heat, humidity, mechanical friction and microbiome dysbiosis under the mask.

The barrier changes can be measured. In a year-long study that compared mask-covered and uncovered skin on the same faces, researchers found significant differences in water loss and hydration between the two areas. That matters for treatment: skin under a mask tends to be both congested and irritated, so harsh acne routines often make it worse. For more on what a weakened barrier looks and feels like, see our guide to a damaged skin barrier.

Where does maskne show up?

Maskne appears where the mask touches or traps air: DermNet notes it mainly affects the cheeks, and the chin, jawline and the skin around the mouth and nose are common too. Typical signs are small clogged bumps (closed comedones), red papules and some pustules along the mask line. In deeper skin tones, a review on mask acne in skin of color shows closed comedones with post-inflammatory hyperpigmentation on the mask-covered cheeks and chin, and the AAD notes that dark spots after acne can last much longer than the acne itself. Preventing breakouts early saves months of fading marks.

Which mask fabric is best for acne-prone skin?

For a cloth mask, choose a soft, breathable natural fabric such as cotton for the layer against your skin. The AAD recommends a snug but comfortable fit without gaps, a soft cotton inner layer, and avoiding synthetic fabrics like nylon, polyester and rayon next to the face. Cleveland Clinic dermatologist Amy Kassouf points out the trade-off: lighter fabrics feel cooler, but tight-weave fabrics and masks with several layers protect better. If you wear a mask for infection control, protection comes first, so fit your skin care around the mask you need.

DermNet also suggests trying different masks to find a material that doesn't irritate you, and considering a lining between the mask and the skin.

How should you wash face masks?

Wash cloth masks after every use and throw disposable ones away after a single wear. The AAD advises washing cloth masks in hot water with a fragrance-free, hypoallergenic detergent, because reused masks trap oil and makeup that irritate skin. A practical routine:

1. Keep a rotation. Own enough masks for a fresh one each day, plus a spare for long or sweaty days.
2. Wash before first wear. Dr. Kassouf suggests washing a new mask first to reduce irritation from fabric finishes.
3. Use fragrance-free detergent and rinse well. Her routine is to wash with a fragrance-free detergent, rinse twice and dry in the dryer.
4. Don't spray masks with disinfectant. DermNet lists this among the habits to avoid.
5. Swap a wet mask straight away. The AAD notes that wet or dirty masks lose their protective value and can irritate skin.

What skincare routine helps prevent maskne?

A short, barrier-first routine works better under a mask than a long list of actives. The goal is clean skin before the mask goes on, as little product as possible under it, and calm, moisturized skin afterward.

Before the mask

• Cleanse gently. The AAD recommends a mild, fragrance-free cleanser. If you're acne-prone, a foaming cleanser with salicylic acid is one of the options Dr. Kassouf suggests.
• Moisturize lightly. Look for ceramides, hyaluronic acid or dimethicone, in a gel if you're oily, a lotion if you're normal or combination, and a cream if you're dry.
• Keep petroleum jelly on your lips only. The AAD suggests applying it to your lips only, since spreading it under the mask can lead to breakouts.
• Skip makeup under the mask, or choose products labeled non-comedogenic.

During the day

• Take breaks when it's safe. The AAD recommends a 15-minute mask break every four hours, a habit healthcare workers have found helps their skin.
• Blot, don't scrub. Gently mopping off sweat and oil is part of the management described in the maskne review.

After the mask

• Wash your face, then moisturize. The AAD's advice for mask acne is to wash your face after wearing a mask and then apply a non-comedogenic moisturizer.
• Hold off on new strong products. Don't start chemical peels, exfoliants or retinoids for the first time while you're masking a lot. If you already use a retinoid, keep it at bedtime and don't increase the amount.

How do you treat maskne once you have it?

Treat maskne like mild acne, gently, and keep the barrier comfortable while the active works. DermNet recommends standard acne and rosacea treatments as appropriate, and the AAD's over-the-counter options for acne include benzoyl peroxide, which reduces acne bacteria; adapalene, a retinoid that unclogs pores; and salicylic acid, which eases inflammation.

• Start with one active. Masked skin is already stressed. If your skin becomes irritated, the AAD suggests cutting back on leave-on salicylic acid, facial retinoids and aftershave.
• Use benzoyl peroxide with care around fabric. It bleaches clothing, sheets, pillowcases and towels, and it can bleach a colored mask too. Our benzoyl peroxide guide covers short-contact use.
• Give it time. The AAD says to give an acne treatment at least 4 weeks, with improvement usually in 4 to 6 weeks and full clearing taking two to three months or more.
• Keep treating existing conditions. If you're under a dermatologist's care for acne or rosacea, the AAD advises sticking with your plan and telling them if your skin worsens while masking.

Is it maskne, perioral dermatitis or rosacea?

All three can flare under a mask, and they need different care. Dr. Kassouf notes that the warm, humid air under a mask can trigger acne, rosacea flare-ups and perioral dermatitis.

DermNet describes perioral (periorificial) dermatitis as clusters of red papules and pustules without the comedones of acne, often linked to steroid use, and warns that occlusive creams and ointments can make it worse. Never put a steroid cream on a rash around your mouth without a doctor's advice. If you suspect it, read our overview of perioral dermatitis, and if redness and flushing are your main issue, our list of rosacea triggers can help you track yours.

How can a selfie skin scan help with maskne?

Maskne tends to come and go with your schedule, so it helps to see whether a new mask, detergent or routine is making a difference. A dated photo record does that better than memory. An app like Pori takes a selfie and returns an overall skin score with a breakdown that includes Pores & Texture and Pigmentation & Tone, and its before/after comparison lets you line up scans from weeks of heavy mask wear against lighter weeks to see how your cheeks and chin changed. Our guide to tracking acne progress covers how to take photos you can compare.

An app is not a diagnosis. It can't tell maskne from perioral dermatitis or rosacea with certainty, so see a dermatologist if your skin isn't improving after several weeks of over-the-counter care, or if you have painful, deep or scarring breakouts.
