I will let you in on a dirty beauty industry secret: sheet masksโ€”which are fiber sheets with holes for your face soaked in skin serumโ€”are overpriced and contain way more product than you need in one sitting. You could just buy a bottle of skin serum and pat it gently on your face, but whereโ€™s the fun (and Instagram selfie potential) in that?

Last year, while browsing the Japanese dollar store chain, Daiso, I found a $2 packet of โ€œcompression masksโ€โ€” little pellets that expand into sheet masks when they get wet. Theyโ€™re cheaper than individually packaged sheet masks, allows for customization with your favorite serum, and look like little candies that you can stuff into your bag for travel.
