Naomi Watts is ''horrible'' at applying make-up.

The 'Insurgent' star has admitted she hardly ever wears make-up when she's not working because she struggles to put it on.

When asked if she is comfortable without make-up, she said: ''I rarely wear any in my day-to-day life, mostly because I'm horrible at applying it.''

However, the 46-year-old beauty has admitted there are times when she has to wear heavy make-up ten hours a day for three months whilst she works on films.

Asked about her favourite skincare product, she shared: ''Cleanser is really important to me, especially as I wear too much make-up most of the time when filming.

''I do shoots that are ten or 12 weeks long, wearing make-up for ten hours a day under lights that push it into your skin. It's then reapplied and layered on. So to cleanse well and take care of my skin is important.''

Meanwhile, Naomi also revealed she opts for facials to get her ready for the red carpet.

She explained to HELLO! magazine: ''I'm a big fan of looking natural and rested. I don't wear much make-up so I like to treat myself to [the] Triad Facial - light microdermabrasion, laser toning plus a gentle flower acid lavender peel.

''I walk out red-carpet ready and you'd honestly never know I'd just had a facial - you just look dewy and fresh. It's one of my secret weapons.''
