Jennifer Aniston staged an ''intervention'' against her own tanning habits.

The 46-year-old actress ''regrets'' not using sunscreen as much as she should have when she was younger so does what she can now to prevent further damage from the sun's harmful rays.

She said: ''I gave myself a sun-tanning intervention a few years ago, where I was basically saying, 'Let's just quit while we're ahead.

''I was not great as a kid with sunscreen. That's one of my big regrets. Now I use Aveeno Positively Radiant Daily Moisturiser SPF 15.''

The 'Cake' star - who is engaged to Justin Theroux thinks it is important to both look and feel good, both for her own sake and to inspire other women of her age.

She said: ''We're going to feel good about ourselves if we see another woman who is 50 and rocking it.

''If society is telling you to sit it out after 40, you diminish yourself. Believe what you feel. If you feel c***py about yourself, it's going to show.''

However, Jennifer doesn't believe that looking good requires wearing make-up as she got used to going bare faced while shooting 'Cake' last year.

She told People magazine: ''When I was filming Cake, I didn't wear any make-up. I was taken aback by how nervous I got about walking outside and knowing that there was probably going to be a whole group of photographers.

''But then I just let go and I didn't care. And over the next five weeks of shooting that, I really loved it. I wasn't attached to make-up. If anything, putting on make-up felt so weird.''
