Even if you don’t need an eczema cure, I’d be willing to bet you know someone who does. That’s because more than 15 million people in the U.S. are suffering from eczema at this very moment. Eczema is an itchy, often painful rash. The typical treatment of steroid creams? Doesn’t really work. Why’s that? It’s a short-term solution that doesn’t treat the real cause.
