I love Clarins products, but this particular one has no effect on cellulite. What it does is make the skin appear slightly brighter because it clearly contains high-quality ingredients. You will see a slight tightening, but there is no way it can combat cellulite. If that is your problem, it really isn't worth spending 50 euros for 1 bottle/month. It's better to save your money and have a few sessions of mesotherapy with a dermatologist, as the direct injection under the skin yields different results than a superficial cream.
