Unless you have a laser or have a particularly serious facial injury, such as local reaction caused by sunlight, you can apply the mask once a day under the guidance of a doctor, but it doesn't need to be more frequent or longer. The regular time is 15 to 20 minutes. For simple maintenance, it is recommended to apply 1 2 times a week, with a maximum of 3 times.
