Jennifer Aniston, 54, shares her four key tricks for looking years younger

Jennifer has spoken about her skin care routine and secrets to maintaining her young appearance.

The actress credited good skin care and lifestyle for this, putting it down to four simple factors.

The Friends star suggested doing skin scrubs, drinking plenty of water, using moisturiser and getting enough sleep can help.

"I would say do a scrub three times a week to really get your skin clean," she told Forbes previously.

"Hydrate - obviously drink, drink, drink lots of water. And moisturise. And I’m going to throw a fourth one in and say sleep."

She has said her daily routine consists of a cleansing bar, toner, serum and moisturiser.

Getting plenty of sleep is also one of Jennifer's recommendations.

Sleeping well has been proven to improve appearance and make the skin look younger.

This is because sleep gives skin cells the time to grow and repair, boosting collagen levels.

Collagen affects elasticity in the skin and water is a vital component of this.

That may be why hydration is also an important step in the movie star's routine.

When hydrated, the skin is more elastic and less prone to damage.

A youthful appearance is the result of genetics as well as skin care and lifestyle factors.

Eating well and regular exercise can also make you look younger.

This is important to Jennifer, who has spoken of her healthy diet filled with salads.

She will also regularly take part in yoga and spin classes to stay in shape.
