This is such a cool product! I received a sample in my Sephora Play! box, along with sample packets of a couple of Origins' best-selling masks. I was already a fan of their Clear Improvement Active Charcoal Mask, but using the Maskimizer Primer before I applied it made the mask much easier to use, and also improved its efficacy! The charcoal mask spread on more smoothly and didn't instantly dry in awkward patches (as all charcoal masks tend to do, in my experience). The Maskimizer spray is cool and refreshing, and it made the charcoal mask more comfortable to wear--I didn't feel like my face was going to crack if I moved my face.
Yes, this is an extra step, but it only takes about three seconds to use. It's a unique product and concept, as far as I know, and I do think it ups your mask game. The only reason I gave it four stars instead of five is because the price is a little higher than I would like to see on a product that isn't strictly necessary for one's mask routine. At a slightly lower price point (like maybe $18 instead of $22 for 3.2 oz. of product), I'd give it five stars.
Bottom line: If you're a regular mask user, this might be worth the money for adding comfort, efficacy, and ease of use to your favorite mask (except peel-off masks; Origins says not to use it with those)! If you don't currently use masks regularly, Maskimizer might not be worth the money for you. However, if you would like to start using masks more often (which I highly recommend--masks are great!), but aren't sure which one to choose, Origins makes masks for just about every skin concern. It's a great brand to try, whether you're mask-less or a mask master!
