Many of us can find fault with what we see in the mirror - but Charlotte's intense hatred of her appearance began to take over her life in her early teens.
"I'd wake up at 5.30am to put my makeup on even though the school bus wasn't until 8.30am," she says.
"I'd be compulsively applying it, taking it off, reapplying it, taking it off again - trying to get it as symmetrical and perfect as possible."
Charlotte says she began to isolate herself, until she couldn't even face going to college except to sit exams. She didn't go to prom as she couldn't face having her photo taken.
She was eventually diagnosed with Body Dysmorphic Disorder (BDD).
