How it works
Niacinamide leads the ingredient panel on this sheet mask. 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. On this panel it sits alongside Euterpe Oleracea Fruit Extract, Dipotassium Glycyrrhizate and Mentha Piperita (Peppermint) Extract. Acai fruit extract, from the Amazonian palm berry. It carries anthocyanins, the same purple pigment polyphenols found in blueberry, and is used as a plant antioxidant.

Key actives
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.
Euterpe Oleracea Fruit Extract
Acai fruit extract, from the Amazonian palm berry. It carries anthocyanins, the same purple pigment polyphenols found in blueberry, and is used as a plant antioxidant.
Dipotassium Glycyrrhizate
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
Mentha Piperita (Peppermint) Extract
Peppermint leaf extract, the water-based extract rather than the essential oil, so it carries far less menthol. It is used as a refreshing herbal extract.
What does Niacinamide do in this sheet mask?
Niacinamide sits among the first ingredients on the list, the tone-evening, barrier-supporting active Korean formulas lean on most often, and its early position here means it is not a token dose.
Is Sodium Hyaluronate also in this formula?
Sodium Hyaluronate sits within the first ten ingredients, one of this formula's moisture-binding hyaluronate forms. It sits alongside Niacinamide on MEDIHEAL's ingredient list for this product.
How is this sheet mask used in a routine?
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. It works as an occasional, concentrated step layered over a completed routine, not a daily one.
Who is this sheet mask suited for?
Normal skin, Dry or dehydrated skin are the best fit for this sheet mask. Patch test on the inner arm before first full use, as with any new skincare product.
