This is the mask pack I use! What's unique is that it's black!! It feels a bit more luxurious than a basic white mask pack, wouldn't you say...? Heh. I think Mediheal is a famous brand that everyone knows without me even having to say it! Ampoule? Essence? Should I call it the basic ingredient of a mask pack? It contains a really generous amount, so it is very moisturizing. Even after applying it to your face, there is still ampoule left inside the pack, so you can squeeze it out and apply it to your neck! If you are looking for a mask pack, give this product a try.
