Mmmm, good question. Well the short answer is yes, it can contribute, but of course it isn’t that simple. When on a high protein diet you tend to eat more dairy and less fruit and veg, you may also be using a protein powder to supplement your diet. All of these factors can upset the ph balance of your skin as well as your hormones. So if you are on a high protein diet for whatever reason make sure you include lots of vegetables and introduce a green smoothie to your diet every other day.
