Natalie Portman has been a natural beauty since setting foot on the Hollywood scene at a very young age. While always a natural beauty, it does appear as though she may have undergone rhinoplasty to make minor changes to the tip of her nose as it appears slightly narrower than in her younger years.
For a woman in her mid-thirties she appears to be aging naturally and gracefully. She is beginning to develop fine lines on her forehead and crow’s feet indicating if she has utilized an anti-aging treatment like Botox, the treatments have been very minimal. She could be upping her Botox treatments in the near future to prevent further deepening of these lines, helping maintain youthful looking skin into her late thirties and forties. As I said before, Botox is a great preventative treatment. You want to start using it before your wrinkles become obvious, not after.
