Review (3/5): They are Ok...
First off these are not the normal hydrogel masks were they feel like cool jelly. These are like the cotton kind with a semi hydrogel backing. Second there is only one set (two eye patches) of eye patches per box. I had some trouble using these as this is the first eye patch I have had to place and stretch. Some stuck and some didn't. I did not see a noticeable difference after using these but I wouldn't expect to after only 5 treatments.
