I'm often sceptical of high-end brands but I got a tiny sample of Chanel Hydra Beauty Serum a while ago. I liked its smell and consistency, so I bought a full bottle at a duty free as a treat to myself after a glass of bubbly on the plane. Now I've been using it for a month every morning under (light) makeup. It makes my skin feel lovely and look very healthy. I'm really amazed as I really expected nothing and I'm prone to lots of skin problems (light rosacea, extreme dryness and hormonal acne).
I tried a sample Genifique as well but couldn't stand the smell and it didn't do anything much to my skin. Are ther any other great serums out there? Have I been missing out?
