hi! aw thanks! this is an amazing question because I find it to be very true. i think it has to do with a couple of things mostly environmental, the sea water def. plays such a great role in clearing up skin (natural salts) and when you eat vitamin C foods and go out in the sun it turns to vitamin D and vitamin D is one of the essential vitamins for great skin. I think fruit also plays its own role in the sense of the source, in NYC its hard to tell the source of things even though they say organic on the label, however i find in other countries there are more local markets, farmers. of course not all countries both most. And lastly the toxins in the air of the environment play their own role too. for instance, in NYC there are alot of toxins in the air / which is natural in a city jampacked with people, subways, etc. These are just a few of my thoughts & opinions :) X
