I am really happy with the price I got this ampoule for. I haven't used peptides in my skin routine until now and I was looking forward to see what the results will be. I don't have wrinkles yet, so I cannot comment on the revitalization of this product, however it really makes the skin look better and feel nicer. Makes sure not to use any acids/exfoliators with it as it won't work as it's supposed to. I have also bought one for my sister and my mother, so they will be able to say the difference.
