If you invest a fair amount of time and energy in make-up but don't have much of a skincare routine, you really could be missing a trick. Healthy skin is arguably the building block of any beauty look, and no one knows this better than Dominic Skinner, global senior make-up artist at MAC Cosmetics.
It might be surprising to hear a make-up artist telling you to focus more on moisturisers and serums than eyeshadows and foundation, but it really does make sense.
"The more you treat, condition and prepare the skin, the less make-up you need, the better you end up looking and the longer it lasts throughout the day," Skinner explains. "So, there really is a knock-on effect."
Don't worry though, he isn't turning his back on make-up entirely. In fact, he refers to make-up as the "fun part", made better if you've properly tended to the canvas beneath.
He's even devised what he refers to as a "mathematical equation" for the relationship between your skin and make-up. "I always say, for every one piece of make-up, put on two pieces of skincare," he says. "It's 70% preparation and 30% application, and if you work on that idea, you can't go wrong."
Another thing Skinner considers absolutely vital is removing your make-up. "However long it takes you to do your make-up in the mornings, how long does it take you to take it off at night?" he asks. "If you were taking 20 minutes, but then you're spending 30 seconds with a wet wipe at the end of the day, things are going wrong."
Taking your make-up off properly and giving your skin a bit of love at the end of the day can help it look bouncier and glowier, helping foundation and other products go on flawlessly come morning.
Skinner is hardly alone in his skincare obsession. In the past few years the industry has exploded with people becoming increasingly conscious about what they put on their face.
Skinner credits this popularity to social media, saying: "I think people want the idea of Instagram filters in real life.
"They see themselves in a filter and think, 'Oh, I look amazing'," and perfect skin is a step towards achieving this."
Skinner has also seen a growing trend of "people wanting that pore-less, flawless skin".
His enthusiasm when talking about his favourite creams and face masks is infectious.
"I am like a Korean woman when it comes to skincare!" he says with a laugh. "I don't really wear a lot of make-up - maybe a little concealer or powder - but I go through probably about 12 different skincare products before I even leave the house."
And yes, that includes three separate eye creams, which he insists all have a job to do.
He is a "big believer in masks" and currently can't get enough of AHA exfoliating masks. AHA stands for alpha hydroxy acids - a holy grail group of skincare ingredients, including glycolic and lactic acids - chemical exfoliants that help remove dead skin cells.
Skinner also uses skincare as an opportunity for some self-care and to give himself a bit of me-time. "Skincare Sunday is the day where I spend about eight hours doing skincare and I love it," he says.
Considering his devotion to the cause, we're not sure he's joking about eight hours.
