Shaklee's Enfuselle Instant Firming Serum might do exactly as it says. I know after I tried it my skin instantly felt firmer, but the feeling didn't seem to last. I don't know if I just got used to it or if it just "wore off". I don't have wrinkles to really judge that aspect with, but it did seem to shrink my larger pores - which is what I was after. However, I didn't personally feel that it was a big enough difference for me to invest in the product a 2nd time.
