Marcia Clark – 64

Marcia Clark is most remembered for her work in the O.J. Simpson murder case for she was the one who served as the Lead Prosecutor. She had quite the troubled past for she was violated at a young age and she claims that this was what had pushed her to pursue a career in law. She also tried acting once, portraying Attorney Sidney Barns on an episode of the show, Pretty Little Liars. Clark definitely has some beauty secrets because she still has a youthful glow even in her mid-60s. We wonder how much money she invested in a skincare routine.
