How it works

Collagen leads the ingredient panel on this sheet mask. Collagen is the structural protein that makes up most of the dermis. Applied on top it is far too large to enter skin, so in a formula it works as a humectant and a smoothing film former. On this panel it sits alongside Niacinamide, Chondrus Crispus Powder and Inonotus Obliquus Extract. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Key actives

Collagen

Collagen is the structural protein that makes up most of the dermis. Applied on top it is far too large to enter skin, so in a formula it works as a humectant and a smoothing film former.

Hydrolyzed Collagen

Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.

Niacinamide

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Chondrus Crispus Powder

Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.

Inonotus Obliquus Extract

Chaga mushroom extract, from the fungus that grows on birch. It carries beta glucan polysaccharides and melanin pigments, so it holds water and can darken a formula.

How to use

  1. Unfold the sheet and smooth it onto a cleansed face, adjusting it around the eyes, nose and mouth. Leave it on for 15 to 20 minutes, then remove and pat any remaining essence into the skin rather than rinsing it off.

Worth knowing

  • Patch test on the inner arm before first full use, as with any new skincare product.

What professionals say

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

  • Topical collagen is a very large molecule that's too big to absorb into the skin.

    Michelle Henry, MDDermatologist, Cosmopolitan
  • Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
