I am very impressed by this product. I have sensitive skin and there are many, many treatments that I cannot use around my eyes, but this was very refreshing, I didn't feel any tingling, which is kind of miraculous, and after the first use the skin around my eyes felt really fresh, hydrated and all the wrinkles were softened, flattened Impressive (after half an hour, hehehe). The only downside, so far, is that the curve of my eyes is flatter and larger than the patches, not as round, so I have to cut out the inner corner to make it fit properly on my lower eyelid. But that doesn't quite bother me TBH, compared to the results. I have tried the Shiseido retinol patches but this ones are way more effective, at least on me. Will definitely repurchase.
