(Cover) - EN Star Style - Emma Watson saw a dermatologist when she developed spots while shooting a Harry Potter movie, but was horrified when the treatment burnt the skin off her face,

The British actress has played Hermione Granger in the wizard film franchise since she was 11. The penultimate movie in the series is out later this month with the final one hitting screens next year, and Emma has been reminiscing about growing up on screen.

Now 20, she finds looking back at her younger self embarrassing. She knows all young people struggle with bad hair or problematic skin while teenagers, but still cant believe her issues were caught on camera.

Thankfully, the boys were going through spots at the same time, so we had a dermatologist doing the rounds. She gave me something that burnt the skin off my face. It was terrible. They couldnt hold filming; we just had to put more make-up on, which made it really sore, she explained. The head of make-up promised me she wouldnt let them put anything out there where my skin looked bad, and I had to trust. But it took a lot out of me to put myself in front of cameras with my skin like that. I didnt really go through a puppy-fat thing, but I went through stages where I looked chipmunky and I didnt feel good about myself.

Emma even had problems while making the first movie, 2001s Harry Potter and the Philosopher's Stone. One of her front teeth came out, causing major continuity problems.

They put a fake one in my mouth every day to hide the gap, she laughed to British newspaper The Times. (C) Cover Media
