Every function of the mask has a separate button in the control panel, so there's no mistaking your choices. I've only used it twice, the purple color, but so far, my skin feels smoother and the pores, tighter. The box was constructed in a way that the mask can be stored back easily, just as when I opened the box for the first time, and the box is very sturdy. Will add more feedback as time progresses. I'd definitely recommend it.
