What does a face mask do? Face masks suck or push (or sometimes both). Mud style face masks are usually designed to suck impurities out of the skin, unblocking pores and fighting off excess oil. Gel/cream masks are designed to push hydration into the skin and flood the surface levels with moisture. Masks are usually used 1/2 times a week. It’s often debated as to whether masks are as effective in comparison to regular effective skincare treatments but I feel they’re a key element to any skincare regime.
