This serum leaves my skin feeling smooth by replenishing my skin's hydration. It contains hyaluronic acid which helps bind moisture to my skin. It doesn't clog my pores and complements the hydrating effects of my moisturiser. If I'm in a rush, I can also use this in place of my moisturiser. How to use: I apply about two drops to my skin using my fingertips. You can also apply this to your neck and chest. #ad
