David said: First it is not always the liver, the gut is equally an issue (loss of intestinal epithelial barrier function, constipation, slow transit time, intestinal dysbiosis) and in some cases autoimmunity, allergy or hormone imbalance is the cause of skin issues. Without knowing your case it is impossible to know why you have this skin issue. It could be many things including your deodorant, leaky gut, a hormonal issue, liver insufficiency, nutrient deficiency (especially vitamin A and D), etc.
