Ahh poor thing, wish I had that much confidence when I was a teenager. I used to crumble into a jibbering wreck if anyone said anything mean to me! I used to get pretty bad acne too, Im 27 this year and have only recently needed to start moisturising my face! I reckon I wont get all wrinkly too soon, which is the payback. Im intollerant to dairy and have found if I do have a sneaky bit I get proper acne spots again. Doctor laughed at me for suggesting it, but seeing as dairy gives me IBS and migranes I dont see why it wouldnt affect my skin either. Bloomin doctors! Hope the dermatologist can help her. Although to be honest sounds like she has such a brilliant attitiude to those girls they wont be able to make her their next victim.
