In large this is down to what we'll call the Kylie Jenner effect; troops of girls have taken her lead and are posting highly-pencilled lip snaps on Instagram. Before Kylie eventually admitted to having had her lips enhanced, she told Grazia in April 2015, "I haven’t had plastic surgery. I’ve never been under the knife. People flashback to pictures of me when I was 12 and say ‘Kylie’s so different’ but how can I look the same from 12-18?" People went mad for her recommended lip liner, Mac's Spice, which sold out everywhere. Then they started sucking shot glasses to achieve her plumped pout and seriously hurting themselves.
