1. Over hydration of skin: The thin face facial mask usually contains more moisturizing ingredients. If applied overnight, it will lead to over hydration of the skin and over expansion of keratinocytes, which may damage the skin barrier and make the skin sensitive and vulnerable for a long time.

3. Dry and tight skin: Although the original purpose of the facial mask is to moisturize, long-term application may make the skin feel extremely dry and tight after taking off the facial mask, because the facial mask absorbs the water on the skin surface and is not replenished in time. Some thin face facial mask may contain tightening ingredients, and excessive use may also aggravate the tightness.
