The 46-year-old star says her job has made her dislike the use of lots of beauty products because she prefers feeling "clean and fresh".
"Most of the time I don't wear makeup. When you're working and people are caking it on your face, it's nice to feel clean and fresh, femalefirst.co.uk quoted Aniston as saying.
"When I go out, I'll just use a tinted moisturiser, a little concealer and mascara - then I'm good to go,” she added.
The Cake actress, who is engaged to 43-year-old actor Justin Theroux, instead swears by traditional methods to make her skin look and feel good.
"Honestly, hydration and drinking water. I've had four bottles already today! It's a big important thing. A lot of people forget about it, but you have to remember,” she was quoted as saying.
"I also firmly believe in the power of beauty sleep - you can be as healthy as you like, but if you don't get proper sleep your body will pay for it,” she added.
