Starting CPAP therapy is a big adjustment, and for many new users, one of the most frustrating early hurdles isn’t the machine itself — it’s mask discomfort. If you or someone you love has noticed red marks, sores, or wounds forming around the nose or cheeks within the first week or two of CPAP use, this is a common issue with a few likely explanations, and there are practical steps that may help.
Why CPAP masks can cause skin irritation
According to the American Academy of Sleep Medicine (AASM), mask-related skin irritation is one of the most frequently reported CPAP side effects, especially during the first few weeks of therapy. A few underlying causes are typically responsible:
- Improper fit or sizing: A mask that’s too tight can create excess pressure points on the bridge of the nose and cheeks, while a mask that’s too loose may shift during sleep and cause friction against the skin.
- Air leaks: When a mask doesn’t seal properly, it’s common to unconsciously tighten the headgear to compensate, which increases pressure on sensitive skin and can worsen irritation over time.
- New-user skin sensitivity: Skin that isn’t used to nightly contact with mask material and consistent pressure can react with redness, breakdown, or what looks like small sores, particularly for people who already have sensitive skin.
- Material sensitivity: Some people react to the silicone or fabric of a specific mask cushion, which can resemble irritation or minor breakouts.
The Sleep Foundation notes that snoring or air leaking around the mask seal — as some new users experience even with the mask on — is often itself a sign that the fit isn’t quite right yet, which can create a cycle of tightening the mask further and increasing skin pressure.
Steps that may help reduce irritation
A few adjustments are commonly recommended by sleep medicine sources for new CPAP users dealing with skin irritation or breakdown:
- Recheck the fit, not just the tightness: A properly fitted mask should feel snug but not tight — sleep clinics generally recommend being able to slide one or two fingers under the headgear straps. If the mask still leaks at a comfortable tightness, the size or style may not be right for that person’s face shape.
- Try a different mask style: Full-face, nasal, and nasal pillow masks distribute pressure differently. Someone getting sores at the bridge of the nose and cheeks with a full-face mask, for example, may find a nasal pillow style puts less pressure on those specific areas — though it isn’t right for everyone’s breathing pattern.
- Use a mask liner or cushion cover: Soft fabric liners can reduce direct skin contact and friction, which may help while the skin adjusts or while a better-fitting mask is sourced.
- Clean the mask regularly: Oil, skin cells, and residue can build up on cushions and worsen irritation; most manufacturers recommend daily or near-daily cleaning.
- Give it time, but don’t ignore worsening symptoms: Some mild redness in the first week can improve as skin adjusts and the fit is dialed in. However, sores that appear to be bleeding or breaking the skin are a sign to address the issue directly rather than wait it out.
When to loop in a doctor or sleep equipment provider
If skin breakdown is significant — bleeding, open sores, or worsening irritation despite trying a different fit or mask style — it’s worth contacting the DME (durable medical equipment) provider who supplied the CPAP equipment or the prescribing physician. Most providers can facilitate a mask refitting or a trial of a different mask style, often at no extra cost within an initial trial period. A sleep medicine provider can also help rule out whether snoring with the mask on indicates a leak, a pressure setting issue, or something else worth adjusting.
