According to the packaging, this wrinkle-reducing serum sells every 8 seconds in the UK. When I put it on my face, it felt nice and left my skin feeling like velvet. Seriously, like velvet. I use a lot of other things on my face (moisturizer) so I do plan to add this to my daily routine, it was nice to try. ) ….. Clinically proven serum effective at reducing the appearance of deep lines and wrinkles for younger looking skin in just 2 weeks…..I was unable to really review this product for what it claims. Love it and will be buying this.
