Does it allow the surgical mask to be reused?
Yes it allows multiple uses of the surgical mask as it prevents the mask from getting soiled on top of shielding your skin from the polyester material of the surgical mask, a synthetic fibre that can cause skin irritation. The 3-ply surgical mask is protective as long as it does not get wet with saliva or other liquids.
Can people use it on its own, or do they have to put another mask in there?
It’s meant to hold a 3-ply surgical mask within the mask slip. 3-ply surgical masks confer protection against droplet-transmission type conditions such as COVID virus
How does the safety/barrier functions of it work?
This mask slip is engineered from LyoSilk, a hypoallergenic plant silk from Dr.TWL Biomaterials. It functions as a skin breathable, protective barrier between your skin and the normal surgical mask which is made of a synthetic material (plastic) polypropylene, which can cause occlusion acne and irritation to sensitive skin over periods of prolonged wear. The washable mask slip also prevents the surgical mask from getting wet with respiratory droplets when one speaks or condensation from breathing, prolonging the lifespan of the surgical mask.
