So i got these in the mail two days ago and was really excited to try them immediately. A little background on me I have very bad dark circles/shadows under my eyes but no bags. I used these the first night (sticking them under my eyes and leaving them there for about 20minutes). When i took them off my under eye area felt very moisturised and comfortable. Although I can't say the darkness under my eyes disappeared, I THINK the under eye area brightened up a little or looked a little better. I imagine these would be good for when I' m very tired as a pick me up type thing. So while i think these are nice, they are definitely not revolutionary. So for the price i think its nice to have these and the box contained a lot of pairs.
