Megan Fox has an oxygen facial once a week.

The stunning actress says it's important that she takes care of her skin so if she's not working she likes to indulge in a weekly treatment to keep her looking at her best.

She said: "I don't have time to do masks, but I love having them done as part of a facial. If I'm not working, I have an oxygen facial once a week. It's important to go out and have a steam and get the toxins out."

The 25-year-old beauty - who is married to actor Brian Austin Greene - also revealed how she tries not to wear make-up when she doesn't have to.

She told Britain's InStyle magazine: "I don't wear make-up when I'm not working, unless I'm going on a date with my husband. Then, I'll do a dewy tinted moisturiser with a lip gloss and tons of mascara. I have a lot of mascara.

"I wash my face and moisturise twice a day with Epicuren Discovery's Bulgarian Rose Otto and apply Perricone MD's Vitamin C Ester Eye Serum a few times a day. I don't wear sunscreen, because I feel like I'm allergic to the chemicals in it. I stay out of the sun as much as possible and always wear hats."
