From Victoria Beckham's skincare secret to hair advice from Cheryl Fernandez-Versini, when celebrities share their beauty tips, we sit up and listen.
However, when it comes to dazzling during the festive season, there's only one girl to go to - Kate Moss.
The 40-year-old supermodel recently discussed her Christmas beauty regime with tanning brand St Tropez. (Remember when she starred in this shoot?) Here are three tips to note from our favourite party girl...
1. Get the glow
A red lip and "glistening skin" is Kate's fail-safe party look. "I love to mix bronzers and highlighters to contour and bring out the cheekbone," she says. "Charlotte Tilbury does an amazing Filmstar Killer Cheekbones duo that I love."
Her other go-to products? "The St.Tropez Self Tan Luxe Dry Oil gives my skin a subtle golden shimmer which looks great for a night out. It's nice to have a neutral glowing face and eyes and then a stronger lip for a pop of colour so I use my hero red 001 Rimmel lipstick which is nice for lips. I like to use the St.Tropez Skin Illuminators to get that extra glow for my skin. They can be used on the face and body to highlight skin and give a radiant glow."
2. Invest in skincare
"I love using oils at night, they make you feel like your skin has been restored," says Kate. "I like going to Nichola Joss for facials - she does this facial massage for lymphatic drainage using Sanctuary Spa Wonder Oil Serum; it's like getting a natural face-lift."
As for her favourite skincare treat? "I really like Crème De La Mer to put the moisture back into my skin – it helps protect my skin against harsh winds in the winter. Also, I like to use Lucas Paw Paw on my lips during the winter."
3. Hide your hungover
"If I wake up in the morning and look tired and puffy, I fill a sink with ice and cucumber and submerge my face," says Kate. "It instantly tightens everything making you feel and look instantly awake. I saw Joan Crawford do it in Mommie Dearest.
"I also like juicing as it gives you bright eyes with a bit of a twinkle and it keeps your hair shiny. And at the moment I am using the Elle Macpherson Super Elixir supplement, I just add it to my juices."
