What kind of mask is this?

It's a facial hydrogel sheet mask made from solidified serum rather than a cream-style wash-off formula. The box contains four individually portioned 37 g sheets.

How do I apply it, and how long should I leave it on?

After washing your face, prepare your skin with toner and spread the sheet evenly over your face. Remove it after 30–40 minutes, then gently pat in the remaining essence.

Can this mask be worn overnight?

Yes. For the optional intensive method, apply a fresh sheet after completing your skincare routine and wear it for more than three hours or overnight. Remove the sheet when finished.

Does this mask suit sensitive or dehydrated skin?

It can suit all skin types, including sensitive or delicate skin. It may be especially appealing if your skin feels dehydrated despite being oily or less elastic.

Is the mask fragrance-free and colorant-free?

Yes. The formula is fragrance-free and colorant-free.

What is the hydrogel like while it is on the skin?

The solidified-serum hydrogel feels cooling. During extended wear, it becomes transparent after about three hours.

Which key ingredients does it contain?

It contains 2,160,000 ppb low-molecular collagen and 10,780 ppm centella asiatica leaf water. It also contains tea tree leaf oil, leaf water and extracts, plus niacinamide and hydrolyzed hyaluronic acid.
