Would you tell someone that your friend is abused?

I have this friend. She’s been abused by her parents for years. She always has bruises on her, and I’m never sure if they’re from her parents or sports, because she bruises easily. Her parents give her everything she asks for when it comes to money and materials, but they don’t give her the love normal parents give their children. They hit her, but I don’t know how bad. I know it takes a huge toll on her emotionally, to the point where she thinks she is a horrible person and doesn’t deserve to live or be happy, etc. All her life, they have told her she is a failure, has ruined their lives, and so on. She does things so nice for them and tries so hard to be the perfect child. She loves her parents, but I know they treat her worse than she lets on. I’m not sure if I should get her help, because I don’t know the extent of her abuse. What would you do?
