BNIB. Millions of women have already fallen in love with Caudalie’s cult favorite product - the Vinoperfect Radiance Dark Spot Correcting Serum. In 2021 it was reinvented: more effective, cleaner & more natural, yet still proven to be 62 times more effective than Vitamin C. This oil-free, dark spot correcting serum is powered by Viniferine - a natural dark spot diminisher to visibly reduce the appearance of existing dark spots and even skintone, providing a radiance booster for the skin.
