Wha'yunsul Green Tea Essential Mask 25g — calming hydration sheet

A 15-minute green tea hydration ritual

The Wha'yunsul Essential Green Tea Mask is a single-use Korean sheet mask soaked in a green-tea essence. Each pouch holds one cotton sheet drenched in a clear, lightly fragranced serum built around green tea extract and moisture-binding humectants. You unfold it, lay it across clean skin, and let it sit for 10 to 20 minutes while the essence settles into the surface. When you peel it away, skin looks calmer and dewier, and feels soft and cushioned rather than tight. It is the kind of low-effort step Korean routines lean on after a long day, a flight, or too much sun and screen time, when the face simply looks tired and dehydrated.

Why a green tea sheet mask

Green tea is one of the most loved plant extracts in K-beauty because it feels so calm and refreshing on warm, stressed-looking skin. Here it is carried in an essence thickened just enough to cling to the cotton sheet, so the moisture stays in contact with your face instead of evaporating. Polyglutamic acid and glycerin act as humectants, drawing water to the surface so skin looks plump and feels supple. Allantoin is a classic conditioning ingredient that leaves the surface feeling smooth and comfortable. Together they give the soft, well-rested look people reach a sheet mask for, without any heavy or greasy afterfeel.

Frequently asked questions

How long should I leave the green tea mask on?

Around 10 to 20 minutes is plenty. Take it off while the sheet is still damp; if it starts to dry out it can pull moisture back off your skin instead of adding it. There is no need to rinse afterwards, just pat in whatever essence is left and carry on with your moisturiser.

How often can I use it?

Two to three times a week suits most people, and you can reach for one any evening your skin looks dull or feels parched, such as after a flight or a long day in the sun. It is a gentle hydrating step, so there is no strong active to build up tolerance to, but there is also no benefit to overdoing it.

Is this single use or can I reuse the sheet?

Each mask is single use. The cotton sheet is fully saturated with one application of essence, so once you have worn it the sheet has done its job. Use a fresh one each time for the best result.

Will it suit sensitive skin?

The essence is built around green tea and simple humectants, which most people find calm and comfortable. As with any new product, patch test on your inner arm first, especially if your skin reacts easily to fragrance. If you notice any discomfort, remove the mask and rinse with cool water.
