This serum is one of a 4-part series by Cantareus Pure Revival.
Its main ingredients are dry snail slime concentrate and dry snail caviar concentrate, not snail secretion filtrate like all the others.
I have been using it for 4 months now and can definitely say it's working. My pores have shrunk, the pesky little wrinkles I was worried about are almost invisible, my face has this glow now - but not the greasy type glow, it looks healthy and fresh. I love it!
The serum itself is very lightweight and disappears into the skin almost instantly. The manufacturer says it contains twice as much active ingredients as the other creams and I believe them.
Serum, then night cream and I wake up in the morning with the smoothest skin I have had in a very long time. Supple, too.
Only con: the price tag is a little high but if you don't use too much, it goes a long way. I did do some research and the other ingredients they have in there are new and very expensive, so I guess you get what you pay for.
