I've tried a lot of masks in my time, but so far I am most happy with this one. With the added oxygen, it really does give you some instant energizing sensations. It makes you feel great on top of doing its job of rejuvenating your skin, sloughing off old skin, and making your skin feel tight, fresh, clean, and smooth. Effectiveness It really does rejuvenate and make you feel more energized. I don't know how they get the oxygen into this formula, but it appears to be the magic ingredient that makes this the most effective mask I've ever used. It really cleanses you skin well. Opens up and cleans out your pores, and then tightens them when done. It's like a miracle! Ease of Application So, so easy to apply. Just pump it on and spread it all over your face. For toning and tightening of your neck, you can also use it there. I mostly just apply it anywhere my large pores are visible. Scent While I normally prefer completely unscented products, the aroma of this one doesn't bother me. It's light and not too heavy of a perfume scent.
