The 15-minute golden time after applying the mask pack

You must strictly adhere to the recommended usage time of approximately 15 minutes for the mask pack.

Many people leave the sheet on for a long time or even fall asleep with it on because they feel it is a waste to throw away the remaining essence, but

It is a fatal habit that strips the skin of moisture.

This is because when the sheet begins to dry, reverse osmosis occurs due to 'osmotic pressure,' causing moisture from within the skin to actually move toward the dry sheet.

Since masks used to maintain moisture can actually dry out the skin and weaken the skin barrier, it is effective to remove the sheet before it hardens and pat the remaining essence into the skin for absorption.
