Wearing masks whether for CPAP therapy, oxygen treatment, or clinical use—is essential for many people, but it can come with an uncomfortable side effect: skin and mucosal injury. From pressure marks and irritation to more serious tissue damage, mask-related injuries are common, especially with long-term or frequent use.
> Why Mask Injuries Happen
Mask injuries usually result from:
- Pressure from tight-fitting masks
- Friction from movement or talking
- Dryness or irritation due to airflow (especially with CPAP or oxygen)
- Moisture buildup, which weakens the skin barrier
- Allergies or sensitivity to materials or adhesives
These injuries often affect the nasal bridge, cheeks, and upper lip, where the skin and mucosa are thinner and more delicate.
> How to Prevent Them
1. Use a Barrier Product
Apply a skin-conditioning layer like Nadu Mask Soothe before wearing your mask. It cushions the skin, reduces friction, and helps protect against irritation.
2. Keep Skin Moisturised
Hydrated skin is more resilient. Use a gentle, fragrance-free moisturiser after removing your mask and before bed.
3. Adjust the Fit (Don’t Over-Tighten)
A snug fit is enough—a tighter mask won’t seal better but can increase pressure damage.
4. Take Short Breaks (If Safe)
Removing the mask briefly during the day (when possible) gives skin a chance to recover.
5. Clean Your Equipment
Regularly clean masks and straps to prevent irritation from sweat, bacteria, and oils.
6. Use a Humidifier
Especially for CPAP or oxygen users, humidification helps protect nasal mucosa from drying out.
> Why It Matters
Preventing skin damage isn't just about comfort—it also reduces infection risk, supports therapy compliance, and
improves quality of life. Research shows that skin irritation is a major reason people stop using essential devices like CPAP machines (Bonsignore et al., 2019). In healthcare settings, staff with PPE injuries report reduced focus and wellbeing (Foo et al., 2006).
