I'd bet if you saw them up close, with no make-up, wigs, hair dyes, photo filters, dermabrasion or fillers, you'd see fine wrinkles and grey hair. Sure, as black people they don't age as intensely from sun or whatnot as other people do, but they get help, both with their appearance and their lives, so they also have less stress compared to non-rich, non-celeb people. I'm part black, and while I don't look like what most people presume 50 year olds look like, in my magnifying mirror *I* see the fine lines that I didn't have at 35, or even 45. That said, Pharrell's a freak of nature, and for someone who's closing in on 100, Cicely Tyson looks great!

There are things called makeup, plastic surgery and pricey anti-aging creams, see the white cases: Jennifer Anniston, Paul Rudd, Mila Kunis, Gwen Stefani, Jane Fonda - you know the surgeon's knife has helped to create their mysterious 'eternal youth' in some of these cases, Paul Rudd may just be lucky but who knows. Also some are wearing sunglasses, that obscures bags under eyes, crows feet.
