Actress Cameron Diaz says that she wouldn't judge someone who goes for a botox.The “What Happens in Vegas” actress believes people choose to undergo the treatment to "feel better about themselves", reports dailymail.co.uk."I have absolutely no judgement on what makes people feel good about themselves. Those procedures are there to help people feel a little bit better about themselves,” Cameron spoke on the Oprah Winfrey Network show."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,” she added.However, the 43-year-old also had some words of warning for those wanting to undergo the procedure, insisting it won't turn back time."The places that the botox doesn't reach are still ageing. So, it's very, very important to know what happens to your cells and, if you really want to age well, how you can manage that ageing on a cellular level through the five pillars of well-being,” the “The Other Woman” actress said.
