Lancome has spent many years and has gotten many patents regarding this serum, so it must work, right? Lets just say that I am a convert. This serum is encased in a beautiful black bottle with a dropper(makes it look all scientific). I love that this serum has been designed for all skin types, even super sensitive. One drop of this precious serum worn under your moisturiser is all it takes. It really hydrates the skin and makes the overall texture look absolutely stunning. Easily absorbed into the skin, this serum is a must in the fight against ageing. Its best to buy the big bottle which retails for R999. Yes, its damn expensive but it really lasts ages and for the skin transformation , its worth every cent!
