This mask is superb. It comes in two pieces so it fits better than other masks. As stated, it’s a Korean skincare product. It does make your skin feel wonderful and hydrated. You will need to use it when you have a few 1 1/2 hours to spend. That’s the amount of time they recommend to keep it on and it turns clear. If you like to use masks, this one is worth the money.

These really work. I wish I could use one every day. They leave your skin very hydrated and smooth looking. There isn't any annoying peeling to do and they are relatively easy to apply compared to a mask you have to apply yourself.

This product worked great for me. It seemed a bit "messy" at first and felt like it was going to fall off my face so, I sat back/lounged on my couch for a bit gently tapping/massaging it onto my face and the mask adhered nicely after about 10-15 minutes. I noticed that it was not adhering to the upper bridge of my nose/inner corners at my eye brows and outer corners of my eyes. I used a small pair of scissors, cut a tiny slit at those areas and the mask adhered perfectly. At an hour-hour and a half, the mask started to turn clear, I left it on for another hour so, 2.5 hours total before removing. The mask peeled off with ease and I noticed my entire face was bright, plump and very moisturized but not at all greasy or gooey. I noticed marked improvement in the appearance of fine lines around my eyes, mouth and forehead. This will definitely be a once a week ritual for me. Use Tip: I noticed one reviewer commenting about a neck mask, which would be great too. When the mask is unfolded, the eye and mouth pieces pop off the sheet so, I stuck those in a line on my neck and noticed a difference there as well.

This mask took a long time to stick to my face, I had to lay down for about 20 minutes for it to adhere. It took about an hour before parts started turning clear. I left the mask on for a total of 3 hours. I wish I could give it the 5 stars, but I didn't get that "glass" glow they showed on all the ads. My skin WAS very hydrated, soft, and looked a bit tighter. Overall a good face mask with befits, however my face did not look like glass.

These are wonderful face masks!! They hydrate your skin like nothing I've used before. You apply it like any other mask. The only down side for me is how long you have to keep it on your face... sometimes that can be difficult, but I make it work. You get pretty effective before and after results!

This is my first Korean skin care face mask and it’s definitely a winner. I have 64 year old skin. I don’t smoke or sunbathe or go to tanning but I do have age spots and adult acne prone skin with breakouts usually on my cheeks, jaw and chin. I have sensitive, fair skin and I break out with rashes and hives easily but have used this 4 times now over a month and a half and it just gives me smooth, soft skin. It’s very slippery and not easy to keep it in place on your face so at first and you need to constantly push it back in place until your skin absorbs some of the copious amount of serum in the mask and in the packaging. I would order this again.

Good product but very sneaky subscribe and save policy where they have you sign up at a very low price in the very next month almost triple the price. Be aware.

I mean, so far so good? I had it on for 3.5 hours and used the mouth/eye hole slots under my eyes and on my saggy chin. My face feels clean and tighter for sure. I tried to take photos throughout the process at different times. Some spots never dried due to overlapping the mask. I have sensitive skin and redness. I washed my face with water and used a Korean toner for redness beforehand. I’m pumped to use it again during the day to see if there is more visual changes. 24 hour update - my skin is shiny and def feels tighter!
