Or that your forehead wrinkles or spidery eyebrows could be down to chocolate?
Naturopathic doctor and skincare specialist Nigma Talib - who treats celebrities such as Sienna Miller and make-up guru Charlotte Tilbury - is convinced food and drink has a direct and sometimes instant impact on our faces, resulting in recognisable symptoms she identifies as 'dairy face', 'wine face', 'sugar face' and 'gluten face'.
'The second a patient walks into my clinic I can immediately tell the sort of foods they tend to over-eat just by checking the way their face is ageing,'
'In fact, I often find myself reading random faces in the street. I want to run up to strangers and tell them to cut milk out of their diet or hold back on the pasta as it is so clear from their complexion that their diet is doing them harm.'
'For some people, just one wheat-heavy day - cereal for breakfast, bread for lunch and pasta for dinner - is enough to cause bloating and puffiness.'
'A couple of glasses of wine can trigger fine lines around the mouth and eyes, and - if you are intolerant - a creamy sauce or a piece of cheese might trigger a spotty break-out or dark circles under the eyes.'
Nigma is not the first to believe that your face can give away the truth about your health. Face mapping is a strand of ancient medicine that links parts of the face with specific organs of the body - just as reflexology does with the feet.
And while many contemporary Western practitioners may scoff at this approach, modern skincare brands, such as Dermalogica, have adopted it as a part of their skin analysis programme. Even the most traditional of doctors would admit they can see the legacy of heavy drinking or lack of sleep in someone's skin.
Over the past ten years, Nigma has seen thousands of patients and has become convinced that what you eat, and its effect on the health of your gut, is fundamental to the way your face ages.
'Any issues with the digestion of certain foods - perhaps you have an unknown intolerance or you eat more of a food than you can comfortably digest - can cause a cascade of chemical and hormonal changes that speed the ageing process internally and externally, with the results swiftly showing on your face,'Certain food groups appear to be particularly damaging: gluten, dairy, sugar and alcohol. Each taxes the body in specific ways, contributing to a cluster of ageing symptoms such as spots, puffiness, changes in skin tone, premature fine lines and wrinkles or sagging'.
'The part of your face most affected - whether it's your forehead, chin, cheeks or eyes - will depend on the part of the body being put under most stress by the food group.
'It's impossible to be prescriptive about how much is too much as it differs from person to person - your best friend might be able to drink pints of milk without any problem, while for you a smear of butter could trigger a breakout.
'But if you can identify your face problem, you can take steps to eliminate - or avoid as much as possible - the food or drink that is causing it and watch the years slip away.'
