I was really happy to score this in the vault. I am currently into sheet masks and what attracted me to this was that they brand said it was formulated with the best active natural ingredients and without the use of harsh preservatives or sulphates. The ingredients' list goes water, glycerin, propanediol, xanthan gum, rehmannia extract, Anti-ageing essence - pentapeptide, rosewood oil, hydroxyethyl cellulose, tremella fuciformis extract, portulaca oleracea extract, palmitoyl peptide, collagen, hyaluronic acid, allantoin, phenoxy-ethanol, argan oil and vitamin citrus. So although there are a few things that aren't so natural like phenoxy-ethanol, overall the list is pretty natural. I should mention that that's the list of ingredients on the mask I have. Essenzza must have reformulated the essence as the ingredients list on the website. So far I've only tried the blue sheet mask from Essenza, ingredients wise I like this one better. The sheet itself is a thin material and is sandwiched between a white plastic layer and blue layer that is thicker material. The purpose seems so that you don't rip the sheet mask which is so thin but has a lot of thick, goopy serum on it. Now I actually happen to have dry sheet masks that are that exact same material for DIY sheet masks. I have actually mixed up my own concoction and soaked them in it and then applied them. The material is really thin so the sheet will drip a lot of liquid and dry within a short time, so I understand why they made the formula thicker and more goopy. The benefits of using this material for the mask is that it sticks on well and you can easily smooth it out eliminating air bubbles so your skin can really soak up the solution, it also doesn't feel as heavy on your skin as ones with a thicker material. The cons of it are that you have two extra layers to help you unfold and apply the mask without it ripping and that you need the serum solution to be thick because the material dries out fast. Also because the blue layer wasn't aligned perfectly so that the mouth and eye holes were in the same place when I applied this mask I got serum on my mouth and eyes and had to squint in the mirror to get it in place. Personally in hindsight having tried out the silk cotton material, I wouldn't use it for a mask because it doesn't give you as much freedom with the viscosity of your serum solution to make the sheet mask user friendly and not dry out in about five minutes. The thick goopy essence is really soothing for dry skin on application, it's easy to smooth out the mask.
