My feeling these strips really work, so I put the five stars. I trust cosmetics from South Korea, at the height of quality. However, for best results, one packet of course not enough, it is necessary to regularly use these patches at least 3 times a week, a few months. It is important to do everything according to the instructions: thoroughly wash and dry face, shiny side stick patches under the eyes, not too close to the lashes, otherwise it may be irritation of the eyes. I glued on for the night, keep a good night not to pull out, but I sleep on my stomach. The skin became more elastic, nourished, fine wrinkles disappear, the large left. But I'm sure that with regular use, skin is visibly rejuvenated. I had no skin irritation. But if you have any discomfort, immediately remove, rinse with plenty of water ..........
