Applying Lip Balm All Day with No Luck? Moisturized Lips by Replenishing 'Body Fluids' from Within

Modern medicine can interpret the Donguibogam concept of 'body fluids' as cellular-level fluid balance, tissue regeneration, and mucosal health. Lip skin is thinner than other skin and has fewer sebaceous glands, making it vulnerable to external stimuli and prone to losing moisture. Beyond simply drinking less water, internal factors have a much greater impact on lip health. First, 'gastrointestinal tract health' is vital. In modern medicine, the weakening of 'spleen-stomach function' in Donguibogam can be explained by indigestion, gut dysbiosis, and leaky gut syndrome. When gut health deteriorates, the body fails to properly absorb sufficient nutrients, such as vitamin B complex, zinc, and iron, and water from food. This leads to systemic nutritional deficiencies and metabolic disorders of fluids, which hinder the regeneration of lip mucosal cells and cause dryness. Second, 'autonomic nervous system imbalance' is also a major cause. Chronic stress excessively activates the sympathetic nerve, constricting blood vessels, impairing blood circulation, and even reducing saliva secretion. When the body is under stress, it prioritizes blood supply to major organs, so blood supply to the skin and mucosa, which are considered relatively less vital, decreases, worsening dryness. Because the area around the lips is particularly rich in blood vessels, it inevitably reacts sensitively to even minor circulatory disorders. Third, one cannot overlook the state of 'chronic inflammation.' Chronic inflammation causes systemic cellular damage and regenerative imbalances, weakening skin barrier function and increasing transepidermal water loss. Diets centered on instant foods and refined carbohydrates induce intestinal inflammation, which can trigger inflammatory reactions in the skin and worsen lip dryness or angular cheilitis. It is akin to a small ember continuously burning inside our body, drying out body fluids. These complex internal factors cause 'deep inner dryness' of the lips, creating a chronic problem that lip balm alone cannot solve.
