So I recently saw these at my local Target and the packet was about $2 and some change so I thought why not try it out... To my surprise I open the packet and it comes with 3 sets of eye patches! Less than a dollar each, AWESOME! Sooo, I put the eye patches on and it feels nice and cool and doesn't slide off your face at all. The packet says to leave on for 30 min. Best part is after you remove the mask your skin has already absorbed the serum so you don't have to worry about rubbing it in or anything! My eyes were definitely not puffy anymore and my under eyes were brightened and so soft to the touch. My eyes feel so hydrated and a perfect base for my makeup! Definitely going to be purchasing these again and again!
