Skincare specialist and beauty guru Deborah Mitchell has some superstar clients - one of whom is Camilla Parker-Bowles.
Deborah, who is also the head of global skincare brand, Heaven, which is worth a whopping £33m, cares for the skin of the Duchess and a swag of Hollywood A-Listers including Gwyneth Paltrow. She's the first choice of fashion designer Victoria Beckham, sisters Kylie and Dannii Minogue and even tends to the swarthy complexion of reality TV start and music mogul Simon Cowell.
Now, she's sharing her tips so that us mere mortals can get a royal superstar glow for 2019.
The good news - some of those tips are dead simple and one is even free!
Keen to learn more? We thought as much - so here we go.
First of all, Deborah says it's important to eat regular meals. Apparently, skipping meals (which plenty of us do when we realise just how hard we went during the Christmas/ New Year period) can cause skin to become dehydrated. Who knew?
"Food digestion is one of the highest forms of hydration for the body," Deborah told the Daily Mail.
Skip the party and instead take a nap. Or, at the very least, get to bed early, says Deborah.
"Whilst you sleep the body encourages and boosts blood flow to the skin, which means you wake to a healthier glow," she says.
"If you don’t sleep enough, the chances are your skin will look dull."
Skip the scrubs too.
Many of us reach for manual exfoliants in a bid to boost our beauty but Deborah says this may be a good time to give your complexion a rest.
"Many people automatically reach for the scrubs to try and get their skin back to normal, but by doing so, you’re just taking more moisture out of it," she explains.
"Flakiness and dry patches is an indication the skin is out of balance and becoming irritated."
Instead she recommends cleansers and/ or creams with high levels of hyaluronic acid to restore moisture.
Finally, acknowledge that party season is officially over and consider giving the cocktails a bit of a rest. You can either cut back to a couple of nights a week or, switch to drinking alcohol neat. That's right. Neat. And here's why.
"Believe it or not, drinking neat (in extreme moderation) is more hydrating than drinking mixed drinks as they take longer to drink over a period of time and also contain less sugar than a lot of mixed drinks. But I’d encourage not drinking at all," says Deborah.
