I can't speak for its effectiveness as a brightening treatment as I only used it once, but I can say that I really enjoyed this mask. The material that it's made of is very comfortable and adheres and forms very well to the skin, unlike other masks I've used that lift or slide during use and need to be adjusted. After 20+ mins there was still a ton of serum left in the mask and the bag, enough for me to generously rub all over my face, neck, hands, and arms (although it is a bit sticky). Most face masks makes my sensitive skin turn red and blotchy but this one did not. In fact, when I removed the mask and patted in the excess, I felt that my skin was refreshed and my skin felt and looked healthy!I will most likely be buying more of these. Also I love the fact that the packaging is recyclable.

Great smell and hydration.
Fits well, stays moist for a long time. Nice!

Helaas moet ik een eerlijk review plaatsen, al was ik liever super enthousiast hierover geweest.. Ik had 2 van deze maskers bij m'n bestelling geplaats voor gratis verzending. De ingrediënten zijn echt top en 100% natuurlijk/geen allergenen, dus dat is positief!
Toen ik het opende, was de vloeistof zó dun dat het wel water leek. Maar daar wilde ik nog niet op beoordelen. Na 15-20 minuten, haalde ik het masker eraf en zat er nog heel veel product op m'n gezicht (alsof niks ervan was ingetrokken). Na lang inmasseren en wachten heb ik het maar doorgesmeerd naar m'n nek. Ik vond ik het wel lekker fris voelen en had ik nogsteeds hoop dat het uiteindelijk effect zou geven. Het tegenovergestelde.. Het deed helemaal niks en het plakte echt verschrikkelijk. M'n haar bleef zelfs aan m'n nek plakken hahah :) Ik kon eigenlijk niet wachten om m'n gezicht 's avonds weer te wassen.. Echt zo jammer! Misschien is dit persoonlijk en elke huid is natuurlijk anders. De meeste reviews die ik las waren namelijk wél heel goed. Maar ik zou zeggen: bespaar je geld en koop een ander lekker masker op korean skincare <3

Unfortunately I have to post an honest review, although I would rather have been super enthusiastic about this .. I've added 2 of these masks to my order for free shipping. The ingredients are amazing and 100% natural / no allergens, so that's positive!
When I opened it, the liquid was so thin it looked like water. But I didn't want to judge just yet. After 15-20 minutes, I took the mask off and there was still a lot of product on my face (as if none of it had absorbed). After a long massage and waiting, I even spread it to my neck. I thought it felt nice and fresh and I still had hope that it would eventually have an effect. The opposite happened .. It didn't do anything and it was extremely sticky. My hair even stuck to my neck hahah :) I couldn't wait to wash my face again at night .. Such a shame! Maybe this is personal and of course every skin is different. Most of the reviews I read were very good. But I would say save your money and buy another nice mask on korean skincare <3
