I was lucky enough to recieve this product to review along with the mask.As directed on the box,I apply this easy absorbing serum every night after cleansing and in the morning before applying moisturiser.Make up glides over and I think this serum has actually helped control the shine I normally experience along my T-Panel.The Serum is a whiteish liquid with a slight natural scent to it,must be the Ylang Ylang. I have been using the serum for about 3 weeks now and can definately notice a smoother texture to my skin as promised!! When I am "big" one day I will definately be investing in the entire range of Beaucience products,they are truely indulgent!
