I'm loving this mask - it tingles and bubbles while removing impurities and giving my skin a refreshed glow. One pump is plenty for face AND neck - it expands when pumped out. It smooths on pretty easily and like I stated earlier, it gives a tingly, bubbly feeling while it works. The instructions state to apply to "slightly humid" skin - I assume that means slightly damp skin. I simply use warm water and a cloth to clean it off my face. My skin looks and feels cleaner and rejuvenated after use - it definitely perks up tired skin. It has a light and pleasing scent and leaves no residue on the skin.
