I have bought a couple of these serums and this has got to be the best one ive tried, a little goes a long way, i only need a quarter of the dropper for my whole face, it sinks right into your skin as soon as you apply it and leaves my skin feeling smooth and soft, it makes a great base for make up, this 60 ml bottle will last me a couple of months usingit every day, i would highly reccomend it to anyone who wants a great value serum which lasts ages and doesn't feel sticky when wearing #RankBoosterReview ii . #Sponsored iii. #Stay-Young
