Nicole Kidman reportedly indulges in beauty treatments costing $7,000 (about R84 600) before she walks a red carpet.
The 'Big Little Lies' actress is said to maintain her flawless, dewy glow thanks to HD Diamond and Ruby peels - which involve having her face scrubbed with jewels - followed by a lactic peel and a La Prarie White Caviar Illuminating facial, which is designed to diminish age spots.
And the 50-year-old star has even tried a "flying ant facial", which costs over $6,000 (about R72 400) and uses insect secretions to make the skin glow.
A source told heat magazine: "Nicole's treatments don't come cheap but she knows it's what she has to pay to look as good as possible.
"She'll happily spend $7,000 as she wants the most advanced treatments and therapists. She's willing to try most things."
While she takes great care of her skin, the 'Beguiled' actress - who has Sunday, nine, and Faith, seven, with her husband Keith Urban and Connor, 22, and Isabella, 24, with former spouse Tom Cruise - previously admitted she doesn't like to spend a lot of time having her make-up done.
She said: "I can't be in the chair for more than 20-25 minutes so I'm like the speed dial of makeup, I'm like, 'Go! Quick! Fast!' because I don't like sitting, I'd rather be with my kids or I'd rather have a work out.
"I'm also trying to manage my time, and I don't know that many women who can sit around in a salon ... everyone's trying to multitask these days so I'm always like, 'Quick, quick! Do my hair and makeup at the same time', but I'm also massively into hydration because I tend to have dry skin so I always put oils on, any oils I can get, I just love moisture and I love a good mask."
And Nicole feels less is more with her make-up and she has "always regretted" it when she's heavily made up.
She added: "Less is more. Whenever I've worn really heavy makeup I've always regretted it.
"I always think people look better with less make-up. I love dewy skin, it's hard to do it but when you just emphasise lashes ... oh, and I love red lips. When in doubt have a red lip!"
