READ THE INSTRUCTIONS

I managed to apply this mash without removing the protective mash... the actual mask is a very thin gel film that is sooooo cool and comfy when applied properly. My skin felt soft treated and pampered but slightly tacky when removed. I'm slightly disssapoinyed with results as the mask fits around the eyes and I expected the eye area to be slightly more treated.... but this mask is meant to puff and hydrate the skin.... but it has the same effect on my under eye area.... quite puffy when removed..... luckily I have the de puffing cryo eye mask to try!!

Great product

I have used this mask only once but i could already see the difference in my skin. My skin was glowing, felt very nourished, hydrated and soft. The mask was very easy to handle and apply. It had a thicker texture than other face sheet masks I was using previously. All in all it is a great product.

hydrates, but some issues

After twice trying other sheet masks and concluding they all seem far to large for my face, I did not want this to go to waste so offered it to my partner to try. He was game, and promised to report back too. Although this mask was thinner than the ones I tried, it was still strong enough for him to move and re-position it as needed, though it was fiddly to remove the 2 net layers before use. Vertically, the mask fitted him well with good spacing for eyes, nose and mouth. He is 5' 10", so no wonder they are huge on me. However the eye holes were a little too close together so the outside edge of his eyes were slightly covered and the mouth hole was a little too narrow , so he could not drink while wearing it. So the size was good vertically, but a little too small horizontally for him. He also commented that there was no allowance for people who wear glasses (though I don't really see how they could do this). Despite these niggles, he said he could put up with it for 20mins, and found the mask itself quite refreshing to wear. After patting in the serum, he said it left his skin sticky (which annoyed him), but his skin was noticeably hydrated and a bit smoother. The next morning his skin was still better hydrated and less dry than the night before, which I thought a good result for him. I asked if he would buy them at £19 each (£95 for 5). He said no, but would consider using occasionally if I already had one handy. I'd say these are a good bet for someone with a large face (or who is over average female height), and who does not mind paying so much for a single use hydrating product. Before a wedding perhaps?

Interesting to try, but that's all

First of all I didn't enjoy the fitting of this mask at all, after taking off the protected film it is so thin that makes it hard to distribute evenly on your face. I didn't notice any WOW effect after. It felt luxurious on skin but that's pretty much it. Maybe just didn't work for me.

Not good

This is one of the worse masks I’ve ever tried. It no where looks like on the model. It fits horribly... I was constantly readjusting it. And now my skin is red and inflamed. Will definitely not purchase again.

great results

As a make-up artist I have found these masks to be helpful to hydrate and plump skin. Definitely notice a difference after using them. Helps reduces fine lines and leaves skin looking fresh. I have seen positive results on many skin types and have used them on those with sensitive skin without reaction.

Pricey

My partner recently treated me to this face mask after I complained the colder weather was making my sensitive skin feel dry and lacklustre. The mask itself goes on fairly easily as it isn’t as slippery as some other brands versions. It instantly cooled and felt nice on my skin and after treatment I could definitely feel my skin felt refreshed and looked dewy. Overall this isn’t a bad product it’s just slightly pricey for the results achieved…..I didn’t see a huge difference between this brand and my usual brand (which is less than half that price) A treat.

Best hydrating mask!

This mask is a must-have for me. I keep them in my refrigerator so they’re chilled when I use them. These are the BEST masks for dryness or if you have any irritation!
