The problem of allergies applies to all products with which we come into contact. Anything can sensitize – food, clothes, cosmetics, sun rays … However, if the product is completely safe (and therefore tested and certified by independent laboratories and institutes) – irritation and allergies do not result from a product defect, but from the individual reaction of each organism to a given product .
The masks help keep saliva and any other droplets – released when you breathe, speak, cough or sneeze – from leaking into the air and potentially transmitting Covid-19 (or other diseases). This is exactly what we expect from masks, but it does mean that the masks trap moisture and bacteria inside by touching the skin. The masks create a kind of seal that prevents moisture from escaping, which results in a humid environment in which bacteria can cause acne, for example, or an allergic reaction may develop on the face.
For very sensitive skin (including children’s skin), it is a good idea to change the mask during the day so that bacteria do not have a chance to grow and damage the skin. It is also important to maintain proper facial hygiene – washing it before putting on the mask and immediately after removing it, using a washing agent appropriate for the skin.
