One week I put on my scars regularly and I have the impression that there has a small change but as they are old and very dug I do not know whether his work. however the big plus point is that in 2 aplication on the entire face I no longer small buttons like, my complexion is radiant and my skin has never carried as well. while his works or not for old scar I recommend as a cosmetic product. adapted to all skin types he also made me hooked!
