Jennifer Aniston has admitted trying Botox injections.

The 42-year-old actress laughed off speculation she regularly has the wrinkle-smoothing treatments, but acknowledged she has had the procedure in the past, though she thought it looked "ridiculous".

She said: "People think that I do a lot of [Botox] injections, but I don't. I'm not saying that I haven't tried it but I see how it's a slippery slope.

"All that cosmetic stuff looks ridiculous on me."

The 'Friends With Benefits' star also admitted she has started taking extra precautions when out in the sun after noticing the way her appearance is changing with age.

She told the new issue of America's InStyle magazine: "I've started getting those little sun spots. Things are beginning to pop out. Even the texture of my skin is changing. So I've recently started zapping the spots and getting spray tans whenever I can. And I've graduated to using SPF 60 sunblock when I'm on the beach."

Despite recently being named the hottest woman of all time, Jennifer - who is dating actor Justin Theroux - admits she hasn't always been confident about her appearance.

She said: "I was a dumpy teenager. My mom was a model and was all about looks, so I rebelled by going goth. It took me years of peeling back the onion to finally stop using makeup as a mask and feel comfortable in my skin."
