Can Leaky Gut Test help with Haut?

The question of whether a leaky gut test can help with skin issues is not well supported by scientific evidence. The concept of 'leaky gut' refers to increased intestinal permeability, but there is no standardized, clinically validated test for it. The gut-skin axis is an active area of research, but robust studies showing a direct benefit of such tests for skin conditions like acne, rosacea, or eczema are lacking. Many commercial tests overstate their utility and often lead to unnecessary supplement recommendations without proven efficacy. For skin concerns, it is better to consult a dermatologist and focus on evidence-based treatments such as topical therapies, dietary adjustments (e.g., Mediterranean diet), or stress reduction. While some anecdotal reports suggest a link, the overall evidence is too weak for general recommendations. Evidence: marketing/unclear.
