Applying a mask every day is not necessarily good for your skin. Although applying facial masks has some positive effects on skin care, such as hydrating the skin or removing the stratum corneum. However, since daily application of masks may cause excessive exfoliation of the facial stratum corneum or excessive removal, it will lead to a decline in the skin barrier function of the face. And because of the long-term application of masks, the skin is excessively thin and tender, so it is easy to cause skin sensitivity, and it is easy to cause damage to the facial skin. Especially when there is some mechanical friction, it is easy to cause localized flushing and redness and swelling reactions. Therefore, applying masks every day is not necessarily good for the skin, and the excessive removal of the stratum corneum may also cause some conditionally pathogenic bacterial infections on the face, and some secondary skin damage, such as acne.
