The mask is phthalate-, paraben-, and sulfate-free, as well as cruelty-free and vegan. I have it and absolutely adore it. In the morning, my skin feels plumped, refreshed, and — not to brag — but I simply glow.
Promising review: "Although I only used a sample-sized portion of this mask, I got a full feel for its capabilities by stretching out my sample over five uses. And WOW was I pleased with the results. For starters, it smells delicious--like real watermelon. Every morning, I woke up with bright, luminous skin that didn't seem like it needed makeup. My skin was smoother and more supple than it's felt in years in spite of the harsh winter air and drying hotel conditions to which I was subjecting my skin at the time. Another note: in the morning, I usually feel a strong compulsion to wash my face because my moisturizer from the night before was too heavy or simply felt like it needed to be cleansed. With this sleeping mask, though, my skin just felt healthy and plump and didn't feel grimy or weighed-down at all. LOVE THIS and will definitely be purchasing the full size soon." —izzypop
