Skin hangover problems are made worse by smoking and wearing heavy make-up.
CACI Founder and CEO Dean Nathanson said: "The effects of Christmas party binge drinking on the skin last much longer than the immediate hangover.
"Consumption of over 14 units of alcohol in one night will take a 40-year-old woman's skin nearly a month to recover fully from and if she goes out a few times over the festive season it will only get worse.
"The toxic effect of the alcohol and sugar remain in the skin long after the hangover feeling has subsided."
LA-based dermatologist Dr Harold Lancer, who treats the Beckhams and Kardashians, has previously warned it can take the skin up to 30 days to truly get over a hangover.
"It takes about two to four weeks for that to regulate," he told The Telegraph.
"Think about it, someone who has been on birth control pills is not usually totally hormonally static for three to six months after coming off them.
"So when you have a hormonal jolt caused by a sugar fest – let's say at a pizza party – there's salt, dairy, carbohydrates and alcohol.
"It will take about 30 days for that to naturally calm down. A glass of the finest red wine is 400 calories of sugar."
He also went on to explain that your hangover cure isn't any better; claiming you may as well 'shoot yourself' if you're going to mop up the night before's alcohol with a fry-up.
"You might as well paint blemishes on your face," he said, instead recommending a bowl of kale with balsamic vinaigrette and grilled organic chicken.
