system may appear abnormal, the body for toxins and abnormal cell clearance ability decreased, easy to make toxins accumulate on the skin, resulting in lower lip black spots.

2, intestinal toxin accumulation

due to intestinal function damage, toxins and metabolites may reach the skin with blood circulation, and accumulate in some parts, such as lips.
