I was new to primers and read great reviews on this product so I tried it out. I was very impressed with how long my foundation stayed on with this primer. It is cost effective and has 30ml of product. I have used it numerous times and my foundation applies really smoothly with it and last a number of hours longer than usual. The packaging is really simplistic which is really pretty. Has no real smell but applies really easily and dries quickly. I would definitely recommend this to anyone who wants a smoother foundation application and wants their make up to last longer while looking like it was just applied.
