Guinot Double Concentré Slim & Firm works synergistically for a visibly resculpted figure
A body innovation from Guinot, the Double Concentré Slim & Firm combines two formulas highly concentrated in active ingredients, brought together in a single bottle to work in perfect synergy.
During the day, the Slimming Concentrate supports the body during its active phase to limit fat storage and refine contours.
At night, the Firming Concentrate takes advantage of the resting phase to improve firmness and reinforce skin elasticity.
Its fluid texture penetrates very quickly without leaving a greasy film. Its light fragrance makes daily application pleasant. A true expert treatment, it can be used alone or as a “body serum” under your usual slimming cream, such as Slim Thermic+, to optimize results.
