This is a really nice mask. I find it to be highly moisturizing for me and notice a nice plumpness and softness to my face after I use it. The essence soaks in quickly and doesn't feel sticky. There is a light fragrance to it. It's very fresh and not overpowering at all. Like others have mentioned there is a lot of essence left over in the package. This is due to the material and not wanting it to dry out. While some will apply it on to of the face mask (once applied), I know others will use it on their arms/chest/neck/etc. I personally save the essence in a jar and add a compressed face mask, giving me a second face mask with the essence. The mask itself is very thin, but surprisingly strong. For a one-size-fits-all kind of deal, the mask fits well on my face. Due to the thin material it is sandwiched between two sheets to help both with keeping it safe and with application. You remove one protective sheet, apply the gel side to your face and remove the other sheet. I will say if you're not big into sheet masks, there may be a learning curve for applying this. With the mask being a thin gel like material it doesn't want to come off of the second sheet easily and you may have to fight it a bit. Nothing too crazy, but it may be an issue for some.
The masks come in packs of three, though I do know at some Sephora stores you can buy them individually. Compared to the multitude of other face masks on the market Farmacy masks are pricy. To the point that I would probably only buy and use these for special occasions. It's one of the reasons I can only give them four stars. Between the price and the ease of use, I know I probably won't purchase unless they are on a good deal. But other than those two things, I truly enjoy using these masks. They are absolutely lovely.
