1. Generally, the time for applying facial mask is 15-20 minutes.
2. For special types of facial mask, such as deep cleaning facial mask or exfoliating facial mask, the use time may be slightly shorter, generally not more than 15 minutes.
3. As for the moisturizing facial mask, if the individual skin feels good without discomfort, it can be appropriately extended to 20 to 25 minutes, but it is not recommended to exceed this time to prevent the facial mask from reabsorbing the moisture in the skin.
