I used to use COSDECO's liposome eye serum, but I didn't feel it was particularly effective for the price, so I switched to this. I have sensitive skin, but it didn't irritate me, and I feel like the dark circles under my eyes have lightened a little. I was a little worried at first because some people said the texture was a little hard, but as instructed, I used a pea-sized amount and it was fine.
