I was a little worried because people were raving about them. I have purchased few other products from Cosrx which I liked. My first impression was it has a VERY water-y(?) consistency. The product glides on and quickly absorbs into the skin. One drop can reach almost 1/2 of MY face, so i recommend using a drop and then build it up. It does have a slight chemical scent to it(?). At first I used it all over face but now I only use it on the areas where I need it. I have not yet seen a result so far but i will keep it for a few more weeks! It has not given me any bad reactions and i have oily+dehydrated skin. For the price- not really here for it.
