Hello. Yes, the emf part also affects Rosacea, but not in the way you say it. At least not completely. EMF and blue light destroy Vitamin A and DHA in our bodies, and also worsens your Leaky gut. This causes fatigue, rosacea, and other autoimmune manifestations, thats why people who do not care about EMF, they see rosacea improvements when they adress their leaky gut (with diet and supplements). But if we could eliminate all blue light and EMF, 95 per cent of our autoimmune conditions would vanish no matter the diet. Trust me, i am a lifelong, open-minded investigator.
