Miranda Kerr uses crystals as part of her skincare routine.

The former Victoria's Secret model has revealed that as part of her morning beauty regime, she applies the Glow Face Oil from her beauty line KORA Organics - using a rose quartz crystal to massage the product into her skin.

In an interview with Australian Vogue, she said: ''I find that my face, especially in the morning, is really puffy so massaging it is really such a good way to stimulate circulation.

I notice a big difference with my skin when I use this crystal because I just feel that it wakes up my skin and it reduces the puffiness. It improves circulation and the way that it curves, you can really get into the jawline and you can get into the eye area and you can just wake up those certain areas and you can really promote that lymphatic drainage that eliminates the toxins.''

The 35-year-old star - who has seven-year-old son Flynn Christopher Bloom from a previous relationship with actor Orlando Bloom, and four-month-old son Hart Spiegel with her husband, Evan Spiegel - has admitted that her routine has somewhat changed since becoming a mother.

She said: ''It's got to be simple, quick and easy, I get in my cleanse and moisturiser routine and I do my mask and I put on my oil and its things that are quick and easy.''

Miranda swears by her brand's organic oil to give her a radiant complexion, and her 28-year-old husband has started using the product and it has completely altered the appearance of his skin.

She said: ''I wouldn't be able to live without that morning and night and it is the same with my husband. He uses it more than I do at night too and it completely has changed his skin.''
