Can Stuhlprobe help with Haut?

Whether a stool sample (microbiome test) can help with skin issues is not yet clearly established by science. There is evidence for a gut-skin axis: the composition of the gut microbiome can influence inflammation and immune responses, which may modulate skin conditions like acne, rosacea, or eczema. However, these connections are mostly based on mechanistic studies and animal data. Consumer microbiome tests like those from MyBody-X show bacterial diversity and specific species, but they are not diagnostic and not validated for skin disease management. Results vary day-to-day and are affected by diet, medications, and lifestyle. Without clinical evaluation and medical guidance, a stool test alone cannot provide reliable help for the skin. Anyone with skin problems should consult a dermatologist rather than rely solely on a home test. Evidence: mechanistic, weak for personalized skin advice.
