I do not remember where I bought this product, but it's probably one of these I purchased from eBay.
This is sleeping mask that you can put it on after cleaning your face before going to bed. When you wake you on the next day it will moisturize and tighten your skin. Many peoples claim that it helps to make their face less swollen on the morning.
I do not know if this really helps with the v-line. But it do helps to moisture my skin and use it the day before I will put make up on.
