I recommend the face mask I use.

This is something I have been using consistently; it is the Medicube Collagen Lifting Pack.

The mask is a bit thin, so it tends to be quite runny and watery, meaning you have to apply it quite a bit. Despite this inconvenience, I keep using it because it works well for me. I have combination skin that gets oily and dehydrated, but after using it, my skin feels moisturized, and the effects last for quite a long time, so I just can't stop using it. Since there is so much product, I apply it evenly to my neck, arms, and legs, not just the mask itself.
