I have been using Caudalie's Vinoperfect Radiance Serum for about a month now, on a recommendation from a salesperson. I bought it to try to get rid of some acne scars I've had for about 10 years -- so I wasn't too hopeful that anything would work. THIS STUFF IS AMAZING. You will not see results right away, but over time, scars will fade significantly. I still cannot believe that it is working on scars that I have had for so long. On top of the visible effects, my skin feels completely incredible. It is so soft and healthy, it has never felt better. My only regret is that I didn't find this product sooner. Yes, it is a bit on the pricey side, but for as well as it works, it's worth every penny. Plus, a little bit goes a long way (I just use 4 drops on my whole face), so the bottle will last quite a while. I can't say anything about how it works on age spots or other marks, but it is a miracle on scars. Try it!!
