I started using the Buffet Serum about 3 weeks ago (the weaker one of the two strengths available as I have sensitive skin) and was just wondering what effect other people have seen with it. I was hoping for wrinkle reduction and more hydrated looking skin... there might have been a slight improvement on fine wrinkles, but skin is drier than normal, and a bit more red too. I know it’s coincided with cold winter weather, so some of that may be to blame, but feeling a bit disappointed at the moment - especially as I bought two bottles after how much other people raved about it! Hoping people will say it takes over a month to really see effects!
