The media could not be loaded. The GLASS SKIN 14Days Miracle Collagen Mask, Ultimate Overnight Mask, Highest Serum Content - Hyaluronic Acid, Niacinamide Serum, Korean Skin Care is the BEST collagen mask I’ve found yet!And I’ve tried so many.This brand was hands down better than ALL the rest. It stays put on your face without ripping or tearing during application.It took about 3 hours to fully turn translucent and be ready to peel off but it began to release the cooling and tightening effect at about 30 to 45 minutes. I left my first mask on for over 3 hours one evening while watching a movie and just being lazy around the house and removed it before bed.I slept overnight in the 2nd one and peeled it off that morning.Some people complain about the mask being impossible to sleep with, depends on if you’re a back or side sleeper I guess, but this mask stayed put for me like others haven’t.Once removed, rub any product left on your face and I promise you’ll SEE and feel the difference after just one of these mask!!Best brand I’ve used yet!
This is a pack of 4 face masks that were made in Korea. These are different than others for a number of reasons. First, this calls for you to wear it for 3 to 4 hours or even overnight. Most other masks I've used call for 15 to 30 minutes. I have no issue with this but just call it out because you have to have a plan to use it. I used this while sitting and watching a movie for the evening. I couldn't sleep with it because I'm a side sleeper but maybe if you sleep on your back, that could work for you.Another reason they're different than others is that they come in pieces. You put the lower half on your face, then the upper half on. This allows for a little more flexibility to get the fit right depending on the size and shape of your face.I was able to leave it on for close to 3 hours. My skin felt very soft, moisturized and dewy afterward. Unlike the other versions, this felt like a real spa product with actually real impact on my skin. Very nice.
Absolutely love this mask. It's great that it comes in two pieces - easier to apply. I left mine overnight, and by morning, there was nothing but a thin film left. Skin felt great, moist, thin lines and wrinkles plumped and not as visible.The liquid it is soaked in is awesome; I have used it as serum for a couple days after using the mask. Great product.
I was afraid these might make my face break out because they are very scented, but they haven't so far! They hydrate really well and the results last a lot longer than i expected - they've basically reversed my forehead wrinkles (which were visible, but minor to begin with, to be fair) I really like that they included the eye & mouth cut out pieces in the package still - i've been putting the eye cut outs directly under my eyes (which masks never cover for me) and the mouth cut out on my neck - you can actually see the reduction of lines on my neck where the mouth cut out was and it looks a bit silly, so i think i need to start moving it about. any way - they genuinely work really well!
Korean beauty hits another home run for me :) These masks are a wonderful addition to me self care routine. This is the first time using a mask that is in separate pieces; top and bottom. It says to wear them for a few hours, and I’m gonna be honest and say I don’t have that level of dedication, lol. I did wear it for maybe an hour because I used them in the evening when I had nothing else to do for the day. They make your skin feel fresh and smooth, my face felt nice and soft after removing. Loving these!
I love these hydrogel masks. These feel a lot less messy than the soupy sheet masks and stayed in place pretty well without slipping. I put a mask on and took a long nap and my face felt wonderfully hydrated and supple after I took it off a few hours later. These are high quality masks and a great way to pamper myself in the comfort of my home.
I like it very much .Skin feels refreshing and moisture at another level.Good size and resistant to use.Easy to apply .Ingredients listed are very good .
This facial mask has Collagen and other vitamins that can helped get my skin looking younger and more beautiful. The mask is easy to apply on the face and it provided a wonderful cooling sensation that feels relaxing. I can feel that my skin silky soft and smooth when I take off the mask. There’s no residues or oily film left behind after removing it. My skin also feels firmer and it’s brighter with a radiant glow. When putting on the mask it makes me look ugly but after taking off the mask it’s a whole new transformation with ageless, tighter skin, and shiny.
I like to use this as part of my home spa treatment and save myself a lot of money by not going to the spa.
Obsessed. I love threw way my skin flows after. I have received lots of compliments since I've been using this product. Tried a different brand which absolutely sucked, it fell apart. This material feels so nice and refreshing on my skin. Totally recommend!!!
