Korea has never failed to amaze me with their sheet mask. They now have this Avajar A-Solution Mask which contains 5 hyaluronic acid that keeps me moisturized and hydrated overnight. It feels so fresh every time I use it. Aside from that, it also relieves dryness of the face. With the extreme cold here in our area, it helped prevent my face from drying out. There's this one time when my face turned red after I used one of the well-known brands of serum, it just so happened that our heater at home was also slightly turned on so my face felt irritated, very hot and itchy. So I tried using this product and I instantly felt comfortable. The redness also disappeared when I woke up the next day. I do not remove this mask until it dries well and absorbs every solution (because I want to have the most of its every drop). This product really satisfies my whole being!
