Allison Williams's air time isn't limited to her hilarious scenes on Girls, anymore! Lately, the actress has been showing off her lit-from-within complexion as the face of Simple Skincare, and her healthy glow can be chalked up to her long-time devotion to the British brand. "I was first introduced to Simple Skincare by a friend in the UK," Williams told InStyle.com exclusively. "I loved their skin-sensitive products and their holistic approach to beauty, so when it launched in the States and they approached me to be their brand ambassador, it was a dream come true!" Check out the star and her radiant skin in the video above.
