So, this potent stuff that Caudalie claims to be 62-times more effective than Vitamin C is viniferine 500, from vine sap, but that's about all I know. This cream comes out of the tube very thick and firm, and it is scented with the same vine scent as most Caudalie products. It goes on as thick as it feels, and it takes a while to absorb but it does absorb well. My skin does get slightly oily in the morning when I wake up, but hey, I'd take a little oil over dry flakes any day!
Interestingly enough, I did try the Vinoperfect Radiance Serum around the same time last year but found it too moisturizing for my face and more suitable for my neck and décolletage, with visible results! Since this is working okay for my face, I'm contemplating pausing this, finish up the Kinara night cream, and go back to this every night to see if it would brighten up my face the same way. That said, this cream is not the Radiance Serum, nor is it a serum at all, which is supposed to be a lot more concentrated. So I might not notice any change but either way it's worth a try. Will update if I see visible results again.
