Korean user insights
What Korean shoppers say about this product
Korean buyers of the Season 4 mask describe it mainly as a heavy, cream-essence hydration sheet rather than a fast whitening treatment. The sheet holds enough essence to stay wet through a full 15 to 20 minute wear and to be used up on the neck and body, and skin is repeatedly described as comfortable and not tight afterwards. The most common complaint is the sheet size and how it sits on the face.
Commonly praised
Cream-type essence is generous enough that users spread the leftover on neck, arms and elbows
Sheet stays wet for a full 15 to 20 minute wear instead of drying out partway through
Skin is reported as hydrated and not tight afterwards, including on dry and combination skin
Finish absorbs with little stickiness, so only a light lotion or cream is needed after
Worth knowing
Several buyers found the sheet cut too wide for their face and had to trim or reposition it
Brightening is described as subtle and gradual rather than the immediate change advertised
One long-term user wanted better adhesion, saying the sheet does not stay put well enough

My mom tried her friends mask and loved it so I ordered it for her. Coupang had the best price as always. Highly recommend for anyone looking for this product\!

Good product but the fit is uncomfortable – short vertically and too wide horizontally. The eye holes are too big so my under-eye and sides are exposed. The nose bridge is not covered because it is too short. This mask seems designed for someone with a very wide flat face, huge eyes like a cow, and a short nose like a pug. Wonder if the manufacturers ever tested it on actual faces.

Almost forgot about this but had to buy it again\! I love this mask so much. It really brightens the skin tone – seriously\! I was skeptical when I first bought it but my skin tone really improved. Saw a video saying it helps with dark spots and it actually does\! Bought it for my husband too – he loves it since he used it before. Perfect for fall skincare routine\!

Saw it on home shopping but ordered from Coupang because they had less quantity. The essence is white colored (first time seeing that) – other masks have clear liquid. The sheet needs careful unfolding or it stretches. My husband who never uses skincare even in summer tried it and said his face still feels moist (even by the next afternoon after using it the night before). Amazing brightening effect – I have yellowish/dark skin but it really makes my face look brighter\!

The essence is abundant – perfect for sweaty summers or dry winters. One sheet gives amazing moisture\! The only downside is the under-eye area does not stick well, so I have to pat it with my hands. Still, came with freebies and long expiration date. Will use for a long time\!

Ik heb deze maskers meerdere keren gebruikt. De geur is licht en fris, maar het resultaat was beter dan ik dacht. Mijn gezicht lijkt een beetje helderder na gebruik. Slechts vijf minuten wachten voor applicatie kon ook handig zijn. Wel viel de verpakking me iets tegen, ziet er simpel uit.
