Mischa Barton was working the demure look and rocking the colors from our Beauty on the Go™ palette at the launch of BritWeek Festival in Los Angeles. Stepping out on Tuesday, the actress covered up her curves in a long white dress. The 27-year-old certainly didn’t look ruffled as she posed for photographs at the party. Makeup Artist Daniel Chinchilla loves using our eco friendly products on celebrity clients. A great way to stay .
