Mischa Barton made another promotional appearance, this time at Superdrug on Oxford Street, London to promote "SAFE" a skin cancer awareness campaign. I'm, all for skin cancer awareness but couldn't they have gotten someone a little bit more charismatic, famous, or at the very least someone who starred in a movie/TV show that was beach related to explain the toll their skin took filming in the sun everyday and how sunscreen saved their life? Mischa's sting on the "O.C." hardly qualifies her to more than a spokesmodel. Is that all she's become? Don't you usually go from spokesmodel to either stripper/porn star or make the jump to acting, not the other way around from former A-list actress to shoe shiller and spokesmodel? More pics after the jump!
