We all have that one friend or family member who insists that eating oily food can cause acne or that fruits can help you get clearer skin. Are these just myths or have they been medically proven?
This was on the mind of Stacey, a Human reader. She recently watched a video of a dermatologist making a claim that food in general, (except dairy products) does not cause acne, e.g. eating pizza wouldn’t cause acne but smearing it all over your face would.
She wanted to find out if there's any correlation between her diet and complexion. She was also curious about the legitimacy of DIY face masks made from fruits.
Dr Shane Abucewicz Tan shared his professional opinion with Stacey. Here's what he had to say.
No proven studies linking diet as a factor that causes acne
Yes, it is true there have never been any proven studies in this regard. In fact, even studies on dairy products affecting acne were rather ambiguous. There's simply not enough conclusive evidence on the effects of diet on acne. 
Theoretically, simple sugars might lead to acne
While healthy food consumption does not directly result in better-looking skin, Dr Shane suggests that there has been a theoretical association of simple sugars and acne provocation.
Simple sugars are pro-inflammatory in nature and therefore have the potential to provoke or worsen breakouts. These include simple sugars and milk. 
However, first-hand experiences show that diet plays a part
While the correlation may be lacking in definitive science, Dr Shane (and several other doctors) can testify that many patients only saw an improvement in their acne after excluding or reducing the amount of sugar-rich foods in their diets.
A healthier lifestyle could improve many things, including skin condition
If you eat well, sleep well, exercise regularly and keep fit in general, your entire body (including its many organs) stands to benefit in the long run.
Studies have also concluded that “fruit and vegetable consumption may represent the most healthy and safe method in order to maintain a balanced diet and youthful appearing skin”. 
That’s enough 'evidence' for you to keep to a healthy diet!
How about putting food on your face?
The general public seems to have a common belief in the benefits of putting raw superfoods which are rich in antioxidants and vitamins on the face.
Doctors have never personally never come across any scientific evidence to support this idea, beyond the beneficial effects you are getting from a moisturizer-type effect.
You might develop an allergic reaction
In addition, you run the risk of developing a mild allergic reaction if you aren't careful, as some of these foods can irritate your skin.
So before you go slapping some blueberries or manuka honey on your face, think again.
It's probably better to eat the food instead
It's better if you stick to more traditional ways of consuming superfoods.
Their antioxidant effects may be more beneficial if consumed this way.
Skincare doesn't have to be complicated
It's best to keep your skin care routine as simple as your face might not necessarily do any better with a hundred different serums and even more moisturisers.
According to Dr Shane, cutting down to the basic necessities and an essential oil-free sunscreen should be enough.
