Love it! I bought this mask just to get the free shipping on an order to sokoglam.com, not knowing much about it, and it didn't disappoint. I applied it after my cleansing routine at night as a replacement of my ampoule. Even when it says to leave from 20 to 30 minutes, I always leave my sheet mask until I feel them drying on my skin, about 40 min. This mask feel very refreshing on the skin, but what I really noticed was that after about 15 min of wearing it, my skin started to feel pulled (in a good way), like if it was having a firming action, something the packet doesn't claim, but I really like. Maybe this was also what helps with the reduction of fine lines, because I did notice a bit of that. One note, when you firm applied, you get a weird aroma, not bad, but strange, kind of like herbal medicine, but it isn't strong and after a little bit I didn't notice it anymore. This mask might become part of my normal rotation of sheet masks. A warning, the ingredients lists Bee Venom as part of the product, so if you are allergic this might be bad for you?
