In short: no they are not worth the money, in my experience. I will not try and persuade you not to buy or not to try, that is for you to decide.
But personally, after trying a selection of P's wide array of "highly scientific" line of cosmetic products for around 6 months in the recent past, I can only conclude that it's yet another con in a brown glass jar/bottle. Sorry, I know it's depressing...but true.
I am a sucker for trying new potions and lotions. The more science offered as a lure, the easier I bite the bait. I've tried many a high end cosmetics. None of them, including Dr P, work beyond improving the TEXTURE of the skin, only. No other miracles, sorry.
Dr P's products are clever in doing so, I'll give him that. They all (well, most anyway) contain glycolic acid, an excellent exfoliant, therefore it makes the skin smoother, more even toned, more luminous and fresh, pores reduced, etc...If you follow his regimen with almost all of his products carrying glycolic you are exfoliating round the clock. That gives you lovely looking refined texture to the skin - not bad at all, especially once you pass the age of around 30. So from that perspective P's products are good. But, I would categorically say they are most definitely not worth the money, as you can achieve the same textural improvement to the skin in a cheaper and less smelly way.
As far as improving/reversing creases as he likes to say, wrinkles and slackened skin, forget it. If it didn't happen in 6 months (not even a hint of improvement or slight reversal of ravages of time from my visage area), can't see how it's going to happen in the next 6, 12, 24 etc months. Mind you at 38, I am not that much of a challenge for his scientific products anyway, as I only have minimal signs of the above mentioned. So if I could not see even a tiny improvement, then how is someone else with real slackening or much deeper wrinkles going to see an improvement?
They can't and they won't as the products cannot work on this level. Otherwise Miss Joan Rivers at the ripe old age of 78, won’t be still needing to visit her plastic surgeon for the x number of times, for yet another stapling work(of art)out on her visage area.
For the sceptics among you that think I haven't tried enough of his products, so I don't know what I am talking about (and for the rest of you to officially declare me shall we say...eccentric:cheeky:, easy now...), here is the extensive list of P's gloop that has said "good morning" and "good night" to my rapidly aging visage (Joan quick, pass the staple gun!), faithfully for 6 months:
nutritive cleanser, serum prep, cold plasma face, cold plasma eye, high potency eye lift, acyl-glutathione, neuropeptide facial conformer, neuropeptide facial cream, face firming activator, high potency evening repair and face finishing moisturiser....:whew:there!
