DEXTEROUS dermatologist Sandra Lee is bursting into the limelight - by popping explosive spots and blackheads on camera for thousands of fans. Better known as Dr Pimple Popper, she has amassed almost half a million fans on YouTube and Instagram combined in the last year alone. She even claims the ‘pimple porn’ is playing a positive role by bringing dermatology to the masses and encouraging people to look after their skin. Dr Lee is based at Skin Physicians and Surgeons, in Uplands, California, and has been a certified dermatologist for 10 years. But it was only a year ago that her popularity erupted when she began posting minor operations on social media.
