I think lifestyle is the main factor determining ageing. And genetics: in the main, people with good bone structure will always look younger longer regardless of wrinkling.
However I believe some products DO make a difference. I think Protect and Perfect perhaps does. I've tried it and noticed a difference. Currently I'm using some cream recommended by Dr Oz and and that's making a difference, I think. However ageing isn't just about wrinkles. There's thinning hair, loss of muscle tone, redistribution of weight, and the mother of all ageing factors-facial sagging.
Wrinkles are an easy target for advertising and of course we fall for it! Who wouldn't?
I must admit though, that, at 57, my skin is clearer, less porous, and perhaps even less wrinkled than it has been in a while. I've b0een using creams, yes, but I've also been making a big effort to take care of myself.
So it's gym, healthy diet, and a good old-fashioned dose of vanity for me! .
