Eye patches are, at heart, a small mask for the under-eye area: a hydrogel — serum in gel form — placed on the skin beneath the eye. They go on clean skin, after cleansing and toner, and some jars come with a small spatula for lifting them out.
Wear time depends on the product, and it is the first difference worth checking. Some need only five minutes — longer if you like; others are meant to stay on for twenty to thirty minutes. Once removed, the patch is discarded and the remaining serum is gently patted into the skin around the eyes.
Although they are called eye patches, they are not limited to that spot: some makers pack two sizes in the jar — larger pieces cover the wider under-eye area, smaller ones are meant for smile lines, the frown line between the brows or the neck. A jar usually holds sixty patches, so one pack covers a whole run of treatments. When choosing, compare two things: how long the patches stay on and what the essence carries — from collagen and caffeine to vitamin C.
