The cooling effect is seriously noticeable the second I put them on, and they stick to my skin without sliding around while I do dishes. I've used about ten of the sixty patches so far for mornings after late nights, and my under-eyes look way less puffy and tired.

I've been keeping these in the fridge and the cooling effect is genuinely noticeable, not just a gimmick. The hydrogel sticks to the skin well without sliding around, and 60 patches in the jar means I don't feel guilty using them every morning.

The cooling effect lasts a good 20 minutes on my skin, and the hydrogel actually stays put without sliding down while I'm reading. I've used about half the jar in a month, and the 60-pack is generous for the price.
