I am 50 too and my skin is quite good. I haven't used any skincare in my life other than the time I was writing (expensive!) skincare commercials at an ad agency and I was given free samples. I used them just to feel "upper class." In the end, I decided that skincare could be a way of loving yourself and you don't need expensive slime to do that. (But no one at the agency bought my genius idea of course. They were all cult members. Plus, you can't make money if you persuade women that just caressing their skin with empty hands will work!)

But sunscreen, huh? Never used that either *scratches head*
