Scarlett Johansson, who initially wanted to train as a dermatologist because of her skin complaints, has revealed that she often gets odd rashes.

The 28-year-old actress asserted that she had every problem and most of the times she gets these weird things, but she knows how to treat them, the Sun reported.

The Avengers star, who now gets her knowledge from watching medical documentaries, also said that when one helps someone to cure their skin it gives them a new lease of life.

Johansson also admitted that she is pretty good at diagnosing other people.
