CPAP Mask Rash and Skin Irritation: Causes and Fixes
A rash, redness or breakouts under your CPAP mask usually come from buildup of oil and sweat on the cushion, pressure from a tight or poorly fitting mask, or less often a reaction to the mask material. Clean the mask daily, wash your face before bed, loosen the fit and consider a liner. A rash that spreads, blisters or does not improve needs a doctor's look.
Signs
- Red, itchy or bumpy skin where the cushion sits
- Breakouts along the mask line
- Dry, flaky or cracked skin under the mask
- Rarely, blisters
Common causes
- Dirty mask
- Fisher and Paykel lists buildup of sweat, oil and dead skin cells on the mask and tubing as a cause of skin problems.
- Poor fit or tight straps
- Pressure and rubbing from an ill fitting mask can cause irritation and sores.
- Skin dryness
- The Sleep Foundation notes that people with dry skin before starting CPAP are more likely to develop mask dermatitis.
- Material sensitivity
- Some people react to mask materials such as silicone, causing redness and itching and, rarely, blistering.
Fixes to try, easiest first
Wash your face before bed
Clean skin seals better and is less likely to break out. NHLBI suggests washing your face before putting on the mask.
Clean the cushion every day
Wash the cushion daily with warm water and mild, unscented soap and let it air dry. Wash headgear regularly too. Avoid harsh cleaners that leave residue.
Loosen the fit
Reduce strap tension until the mask just seals with the air on.
Use a mask liner
A fabric liner puts a layer between your skin and the cushion. The Sleep Foundation lists liners for reducing irritation.
Ask before using creams
Barrier creams or petroleum free moisturizers can help some people, but ask your provider first. Petroleum based products can break down mask materials.
Try a different mask with your clinician
If irritation sits in one spot, a mask with a smaller footprint may help. If you suspect a material reaction, ask your provider about alternatives.
See your doctor if the rash spreads, blisters, oozes or shows signs of infection such as warmth, pus or fever, or if it does not improve after a week or two of cleaning and refitting. A possible allergic reaction to the mask material should be checked so you can switch to something your skin tolerates.
Supplies that can help
Soft fabric liners that sit between your skin and the mask cushion to reduce skin irritation, red marks and the noisy leaks some people get from …
Plain, mild dish soap is the cleaning agent most CPAP makers and the FDA point to for masks, tubing and humidifier chambers.
Pre-moistened wipes for a quick daily wipe of the mask cushion, mostly to remove skin oils between proper washes.

Frequently asked questions
Can you be allergic to a CPAP mask?
Yes, though it is less common than irritation from dirt or pressure. The Sleep Foundation notes mask materials such as silicone can cause allergic dermatitis with redness and itching. If you suspect it, talk to your doctor and equipment provider.
Why am I breaking out where my CPAP mask sits?
Oil, sweat and dead skin build up on the cushion and transfer back to your face. Clean the cushion daily and wash your face before bed. A liner can also help.
What can I put on my face under my CPAP mask?
Ask your provider before applying anything. Petroleum based products can damage mask materials. Some people use barrier creams or petroleum free moisturizers with their provider's approval.
