Hi,
I have been using the first one since it came out when I was in my 20's and was impressed with the results, definitely.
I'm now 33 and was about to repurchase again, but then thought, maybe it's time to move on to the Intense one- the next one up. Think it's designed for 35-45 yr olds and whereas I'm told I don't look my age, I can't see it will hurt 
So if you use this, which one and how impressed, or unimpressed are you with the results?
TIA
