How long should I leave the mask on for a standard treatment?

Leave it on for about 40 minutes. Then remove it and gently pat or massage the remaining essence into your skin.

Can I leave this mask on overnight?

Yes. You can wear it for more than three hours or overnight as an extended treatment. The hydrogel may gradually turn transparent, and the timing can vary by person.

Which half of the two-piece mask should I apply first?

Apply the lower section first and align it with your mouth. Then place the upper section around your eyes and smooth both pieces along your facial contours.

What should I do with the remaining essence after removing the mask?

Gently pat or massage the remaining essence into your skin, then finish with face cream.

How does the mask feel and what finish does it leave?

The cooling hydrogel sits closely against the face and leaves a fresh, dewy-looking finish. It gradually turns transparent during extended wear.

What skin needs is this mask best suited to?

It can fit all skin types, with especially clear appeal for dehydrated or dull-looking skin, uneven texture and occasions when you want a quick glow boost.

Does the ingredient list contain fragrance?

Yes. The ingredient declaration lists Fragrance or Parfum, so the formula is not fragrance-free.

PRODUCT DETAILS

Hello, glow. When your skin feels dehydrated or looks dull, this hydrogel mask offers deep hydration and a radiant, glass-like glow. It is also recommended for uneven-looking texture or whenever you want a quick boost of radiance.

Separate upper- and lower-face sections create a cooling hydrogel fit that sits closely against your face. After use, your complexion is left looking fresh and dewy. The gel gradually turns transparent during longer wear, with timing that can vary from person to person.

Collagen extract and atelocollagen support firmer, plumper and smoother-looking skin, including a softened look to fine lines. Niacinamide and sodium hyaluronate help create a more even-looking finish with refined-looking texture and pores.

You can enjoy it as a standard mask or choose an extended or overnight treatment. Each box contains five masks with 35 g of product in each one. The ingredient list contains fragrance, so this is not a fragrance-free formula.
