I was ok with my hair going gray, but not my eyebrows--they just disappear...I use a combo of brown powder with a little brush that maybe is meant to be shadow, then mascara, then wipe off the excess after it dries and then the powder again. Looks pretty natural.
Also agree that fat under the skin is one secret--I have no lines between my eyes or at the corners and am just beginning to get a couple faint ones on the forehead and I"m 70. At one of our high school reunions someone asked me what me secret was and I said gain 5 pounds every year...she thought I was joking. Needless to say that's not the healthiest solution!
I also use Oil of Olay for sensitive skin WITHOUT the SPF, which is now apparently off the market... I'm on my last bottle and can't find any more... I went to their website which is full of people complaining that it is gone. You think they'd notice. Their regular version, which is pink, feels heavy as do the SPF versions.
I also use their eye firmer thing...tiny bottle that only lasts a month ... in the last few years, and I think it makes a difference. I agree...moisturizer is the key...and fat. And it is best to start it preventively, before you have wrinkles.
I also try to remember something my grandmother told me when I was about 7 and asked her if the deep sharp line between her eyebrows hurt--it was so sharp and deep it looked like a cut. She told me to remember that we would all have wrinkles some day, our only choice was to choose whether they'd be laugh line wrinkles or frown line wrinkles---maybe not totally true, but I admit I do rarely frown--if I'm displeased I'm more apt to raise my eyebrows and do the "look" than frown.
