Yes it’s true that there have NEVER been any proven studies linking diet as a factor in causing acne. Even the studies on diary was equivocal.
Having said that, I tell my own patients to stay away from certain types of foods if they think it’s triggering acne. Moreover, I’m pretty sure unhealthy diets can’t be good for the skin in general!
Conversely, if you eat well, sleep well, exercise and keep fit, not just your skin, but all your other body organs benefit. So yes, I’d say a healthy diet would have benefits on your complexion.
For some science evidence on the link between nutrition and skin agin, you can check out this article here. It concludes that “fruit and vegetables consumption may represent the most healthy and safe method in order to maintain a balanced diet and youthful appearing skin”.
Also, is putting raw superfood rich in antioxidants and vitamins on the face beneficial and recommended?I put foodstuff such as raw manuka honey(UMF 16+) on my face, I tried putting blueberries but I think my skin got irritated.
I’ve never seen any science evidence behind “putting raw superfoods on your face” myself, beyond the beneficial effects you are getting from a moisturizer-type effect. Having said that, you of course also run the risk of developing a mild allergic reaction, as some of these food stuffs can be irritating on your skin. Personally, I’d stick to eating these super foods for their antioxidant effects, and use a normal moisturiser.
