Why a 2% Pure Vitamin C Sheet Mask?
Vitamin C is one of the most loved brightening ingredients in Korean skincare. In this face mask, 2% pure vitamin C is suspended in a generous, moisturizing essence so it stays in close contact with the skin for the full 10–20 minute wear time — the signature advantage of a sheet mask over a rinse-off treatment. The result: skin that looks brighter, fresher and more even after a single session, and progressively more radiant with regular use.
Unlike ordinary non-woven masks, the 100% TENCEL sheet is made from eco-conscious lyocell fiber. It feels cool and silky, clings closely without slipping, and releases essence evenly across the face — ideal for a brightening face mask you actually look forward to using.
How to Use This Korean Face Mask
Start with freshly cleansed, dry skin. Apply toner if it is part of your routine.
Unfold the TENCEL sheet and fit it to your face, smoothing out any air bubbles.
Leave on for 10–20 minutes while the vitamin C essence absorbs.
Remove the sheet and gently pat the remaining essence into the skin. No rinsing needed.
