Garner says she does try to take care of her own skin and hair.
"My hair philosophy is the same way as how I approach makeup, which is that if you take care of your skin and hair, then you should feel good without adding anything major.
The star also advised people to direct their energy elsewhere rather than obsess over trying to "fix something on your face".
"Look in the mirror less, obsess less, and look at the rest of the world to see what you could be using your time for instead," she said.

Garner has previously spoken of using Botox, saying she has used it a few times, but didn't like it.
