Why Skin Irritation Happens - Foam cushionsUpdated a month ago

Foam Cushions (e.g., memory foam–style masks):
Foam feels soft initially but has unique challenges:
Foam can create abrasion when worn directly on the skin
It can trap sweat, oil, and bacteria
Foam cannot be sanitized
Wearing foam directly on the skin for 30 days (the typical replacement cycle) may increase irritation or breakouts
A liner provides a hygienic, breathable barrier that keeps your face from resting directly on the foam surface.
