My friend is forty something but she looks younger than her age. So I asked her "What makes you look so much younger?". She answered jokingly in Chinese "天生麗質" which means her beauty is naturally born. So I'd like to know if the following sentences are correct or comprehensible to native English speakers. 

1. I was born this way.
2. I was born beautiful.
3. I was born with a beauty.
4. I am a born beauty.
5. It just comes naturally.
6. I guess it’s a gift from Heaven.
7. It must be genes.
8. I guess it's in my blood.
9. It's gifted.
10. I was born with beauty.
