I dont know how to describe this product, its like a thick liquid. When I first received a sample, it said take the liquid and press it into your skin! When I use my Retin A to clear my skin you can get peeling for a few days after which is more noticeable after you put on your makeup. I took this and pressed it into the skin and the Flaking was GONE! I did not even mess up my makeup and you couldn't tell. For that this product to me was AMAZING! I immediately purchased he full size and couldn't believe how large the product was. I think you could even press it on your skin before makeup as well. This is one of those amazing Korean beauty product that I would recommend.
