Cameron Diaz understands that people choose to use botox to "feel better about themselves" and wouldn't judge anyone who opts for it.

She said: "I have absolutely no judgment on what makes people feel good about themselves. (Those procedures) are there to help people feel a little bit better about themselves.

"If they do feel better about themselves, then those procedures have worked. I have no problem with that. And (in) a lot of instances, it does make you look like you've taken a nap... or that you might be a little younger than you looked maybe the day before."

However, the 43-year-old actress also had some words of caution for those wanting to undergo the procedure, insisting it won't turn back time.
