Elle Macpherson doesn't wear make-up "at all".
The 52-year-old Australian supermodel - who made her modelling breakthrough in 1982 at the age of 18 - has admitted she hides behind a pair of sunglasses because she doesn't don any cosmetic products, although she doesn't like being bare-faced.
Speaking to PEOPLE about her beauty secrets, the golden blonde star said: "I don't wear make-up at all.
"That's why there are so many pictures of me with sunglasses on! Honestly, I don't love the look of my skin bare, but I feel it's best for it.
"I want to experiment with trends, but as I've become wiser, I've realized that less is more."
Despite having filler injections to reduce the signs of ageing, the 'Britain and Ireland's Next Top Model' host has become more accepting of her wrinkles, although she wished her skin care was better when she was younger and she used sunscreen instead of basking in the Australian rays wearing only baby oil.
She explained: "If you see wrinkles, ignore them.
"Of course I think about lines. There have been times in my life when I have tried really hard to get rid of them [like with fillers], and it doesn't work. So I tend to leave all that alone as much as possible. Ultimately I think nutrition, sleep, love, laughter and water is the most magical recipe for a beautiful face.
"[But] I wish somebody had told me that the most important tool was sunblock. I grew up in Australia in the '70s, when you used baby oil and a reflecting board to get as tan as possible because that was cool. Now I wear SPF 50 on my face, my chest and my hands and get checked regularly."
Meanwhile, Elle - who gained the nickname The Body because of her streamline physique - has admitted her days of swanning around in a skimpy bikini are long gone.
She said: "I don't prance around in a bikini anymore, or a one-piece, or cut off shorts, or very short dresses. At this point I like to keep it simple and not adhere to any trends. That's the secret--the beauty of a woman as she matures is not how she tries to look younger but how she adapts to her new found maturity."
