I'm still using the sample I got. This is an excellent serum, doesn't feel sticky. Leaves your skin soft, firm, glowing and works well with Cream De La Mer. It does what it supposes to, also help to fade my acne scars and it controls my oily sensitive skin. Unfortunately, I saw results only after couple of weeks, just like Cream De La Mer. I use it under my eye area and my lines have disappeared. I will keep on using Cream De La Mer and Face Serum, until I find something that give me the same results, but at a cheaper price.
