I've stayed loyal to my Origins Clear Improvement mask for over a year now but my lovely little sister bought me a RMK mask to test out because "it makes your face soft and glow-y" she's very picky so if it's good enough for her, it's good enough for me.
The packet is filled with a liquid so the jelly doesn't dry out (I wasn't aware of this so had to change outfits straight after using it- clever!) and the jelly comes placed between two plastic sheets. The sheets smell fruity but aren't overbearing. When taking the first plastic sheet off you have to be very careful that none of the mask is caught on the piece you're removing or the jelly gets stuck together. Then place the jelly, still with one piece of plastic on, to your face until you have aligned all of the holes. Once this is done, the other plastic sheet can be removed.
For 15 minutes you will look like you've just stepped off the makeup van for a horror movie but after that you are left with radiant, moisturised skin. I tried to take a photo but the camera couldn't catch a difference even though there was a very clear one in person. My skin looked more plump and bright after using this. I did, however, notice that the results were very short term and only lasted a day. Therefore, I highly recommend this before a big night out or if you're feeling particularly tired. It is a bit pricy at £40 for 4 from Selfridges but makes for the perfect pamper treat.
