The US actress Scarlett Johansson initially wanted to train as a dermatologist and loves helping people with skin conditions, something she feels she can relate to, as she suffers skin complaints herself.
She said: "I've had every problem, I always get these weird things [rashes]. At least I know how to cure them. When you help someone to heal their skin it gives them a new lease of life. Have you ever met someone with a horrible skin condition? I'm good with that."
The 28-year-old beauty apparently gets a lot of her insider knowledge on keeping skin healthy from watching documentaries about it.
She told the February edition of Britain's Elle magazine: "I'm pretty good at diagnosing other people. Fungal issues are pretty obvious. It usually an infection combined with poor hygiene.
"It comes from watching a lot of medial programmes. Real medical programmes, like documentaries."
