I can see why this has being touted as being the brightest star in the YVES ROCHER Hydra Vegetal range. It really works! I use it after cleansing and toning at the end of each working day and it works so well that I sometimes even skip moisturizing after that :D I love the pump, which is ergonomic and practical dispensing me the exact quantity that I need.. no wastage, yaay! Most important is the serum itself; which is gel-like in consistency but neither too thick nor too runny. Just nice and absorbs quickly and easily into my skin without leaving any irritating sticky sensation. Right upon the first application I could immediately feel the difference... my skin feels instantly hydrated and I also love the light refreshing herbal fragrance too! :-)
