I've recently started dabbling in his line and have to say I am loving it.  I hear negative reviews saying his products do "nothing" for people, but perhaps they don't use retin-a.   I LOVE that they don't contain retinol.  Lines that slip in the retinol invariably ruin me and must be returned!    I seem to benefit from the supplements and anti-oxidants in these products.  They enhance my retinoids and Vit C regimen perfectly and without irritation.  The DMAE (his anti-oxidant based on salmon oil) tingles, but that tingle goes away in a few minutes and is nothing like stinging.    I haven't used any of his high-powered heavy hitters in that you won't catch me pay $470 for ANY serum, but the ones I'm liking so far are:

Active Tinted Moisturizer with SPF 15 - has his signature actives (DMAE, Alpha Lipoic Acid, Vits C and E).  This one suffices for foundation, moisturizer, SPF and makeup primer when I use this in the a.m.  I wouldn't recommend it for oily skin, though, unless used sparingly.  Gives off quite a sheen that even I have to dust with powder.

For eyes - a gentle Vit C ester serum and Allpha Lipoic eye cream.  Like this duo very much.  Sinks right in and the C lightens circles under eyes without irritation.

Face Finishing moisturizer - I think any skin type could use this gem.  A little dab goes a long way.   I use it alone or over my retinoids.  Never greasy.  Sinks right in.  Rose scented but not the type of fragrance that would irritate my skin.

Am interested in hearing if any of you have used these products or any others from the line.
