A really affordable line of sheet masks that do the job. The sheet is quite thick and sticks onto the face well. I wouldn't recommend leaving it on for more than 15mins though, as the mask is basically dry after that and might actually end up taking moisture out of your skin. My favourites are the hyaluronic and propolis.
I have super sensitive and reactive skin and i'm in the process of trying to heal my skin barrier. Yesterday my skin began reacting really badly to something - not sure what - and since then whatever i've put on my skin has burned and itched. I thought i'd try and calm my skin down with this mask and WOW it really worked!! It felt so nice and soothing and it completely calmed down all of my redness.
