To buy: $14 (was $19); amazon.com The marker of a truly great eye mask is how quickly it works, how the cost per set shakes out, and whether the benefits stick around for longer than the five minutes after you take them off. Speaking to the former, shoppers say puffiness immediately deflates on contact with the masks, earning the honor of being called “a mom must-have” (especially after a long night of wine and FaceTime). They’re not one-and-done, either, which is good news for both us and the environment. The FreshMes come soaked in ample fluid, so much so that shoppers use them on their frown lines and forehead after 20 minutes of undereye use — and still see the patches intensively tighten and smooth out wrinkles. The power doesn’t stop there, since even notoriously stubborn dark circles aren’t immune to the patches and their solution (love a double meaning). Shoppers say their undereye circles have totally disappeared, even shadows that made it seem like resistance was futile. One mother of three toddlers notes that though her and her husband are often sleep-deprived and have the circles to show for it, the patches are a godsend. “My undereyes are instantly so plump,” she writes, “I swear these give me back seven years of my life.”
