Dita Von Teese reveals her number one secret to flawless skin at 51 - and anyone can do it for free: 'It works miracles, I wish I knew sooner'

Burlesque star Dita Von Teese has revealed the secret to how she keeps her skin 'flawless' at 51 - and it's free.

The model recently went on Bunnie XO's podcast 'Dumb Blonde' and shared the one thing she does every night to keep fine lines away.

'I know no one wants to hear this, but I wish someone would've told me how good it is for you to sleep on your back when I was young,' she said.

The dancer taught herself how to sleep on her back four years ago and said the new change in routine 'worked miracles' on her skin.

Australian registered nurse and anti-ageing specialist Madeline Calfas, previously revealed sleeping on your back can assist with headaches, prevent wrinkles, and helps with overall spine alignment.

'I know where one of my wrinkles came from - sleeping on my face on my pillow,' Dita said.

You can train yourself to sleep on your back by placing a pillow under your knees to relieve spinal pressure.

Two pillows can also be used under your head to make breathing easier and add support, but this sleeping position is not recommended for those with lower back issues or sleep apnoea. 

The burlesque star shared her process: 'I close my eyes, put meditation on, and sleep with my palms up so it keeps my shoulders back.

'I do sometimes move in the night but I'm a light sleeper so I can catch myself.'

The star revealed why it was important for her to make this small change in her routine. 

'It's all fun and games and until you realise the collagen's really going,' she said. 'Some of the marks on my face are from my sunglasses and they'll stay all day.'

Lying on your back helps to prevent wrinkles on the face and chest as the skin is no longer subjected to hours of creasing due to body positioning and sheets or blankets.

When you crease your skin, it pushes the skin matrix (which comprises of collagen, elastin and hyaluronic acid) out from underneath the skin.

'As we age, our skin matrix production slows down, and creases start to become etched in, progressively getting deeper the longer we do it, and the older we get,' Ms Calfas said.

'This applies to the skin around our décolletage as well, so sleeping on your side with your arms crossed over promotes the creases and wrinkles in between the breasts.'

Dita also religiously uses sunscreen every time she steps out. 

Wearing sunscreen every day will protect you from skin cancer - one of the most prevalent cancers in Australia - but it also keeps away fine lines and wrinkles.

Sun exposure also causes sagging over time, which is why dermatologists also recommend using sunscreen as a preventative measure for physical ageing.
