What skin care line did you notice (I mean really notice) a big diff. in your skin?

I keep thinking........and thinking...... and

okay, well really I have never seen a OH MY GOSH after months of using a line, I'm still waiting for that and I think that's why I keep trying new things. I used Perricone over 18 months and really didn't see any diff. in my skin (and I used it day and night...NO FAIL) - this was over a year ago but that is just an example.

Right now I am using the SSC Glycolic kit at night - been using it for 3 weeks now, even the Gommage....Same story - I don't see any change or improvement or glow in my skin like all the reviews claim

I guess I just want to hear about your WOWS, something you are so happy you tried or even an entire line you are very happy with.
