Mediheal N.M.F Aquaring Ampoule Mask N.M.F 아쿠아링 앰플 마스크
Mediheal's best-known hydration mask and one of the highest-selling sheet masks in Korea. The essence is humectant-led — hyaluronic acid, panthenol and the natural-moisturising-factor components the name refers to — on a thin cellulose sheet that clings reasonably well. Nothing in it is exotic; the appeal is a generous volume of well-judged hydrating essence for very little money.
What it is built around
Who it suits
Any skin type that is dehydrated, and particularly useful the night before an event or after a flight. Sensitive skin usually tolerates it, though a patch test is still sensible. Oily skin can use it with little risk of congestion. It is a top-up rather than a solution — no weekly mask changes baseline skin.
How to use it
After cleansing and toner, on a clean face, for fifteen to twenty minutes. Take it off before it dries out, press the remaining essence in, then follow with moisturiser to seal it. One to three times a week is plenty. Use the leftover essence in the sachet on your neck.

What is an ampoule in K-beauty?
An ampoule is a highly concentrated Korean skincare treatment, stronger than a serum, used to target specific concerns like dullness, dryness or fine lines. Applied after essence and before moisturizer, it's typically used in short bursts or when skin needs an extra boost.
What is a sheet mask and how often to use it?
A sheet mask is a serum-soaked fabric or hydrogel mask, a Korean skincare staple, used to flood skin with hydration and active ingredients for 15 to 20 minutes. Most people use them a few times a week or as an occasional boost, applied after essence and before moisturizer.
What is the difference between essence, serum and ampoule?
Essence is the lightest and most hydration-focused, serum is more concentrated and targeted, and ampoule is the most concentrated of the three. The boundaries are marketing convention, not regulated definitions.
