Does Your Face Turn Red Constantly? Rosacea, a Warning from Skin Heat Toxin

Modern medicine refers to jusabi as rosacea and classifies it as a chronic inflammatory skin disease. The concept of heat toxin in the Donguibogam is closely linked to the inflammatory response in modern medicine. Rosacea is not merely a problem of the skin surface, but the outcome of complex, intertwined bodily systems. It is known to arise primarily from a combination of genetic factors, abnormalities in the immune system, and neurovascular regulation dysfunction in the skin. In particular, hyperactivation of neuropeptide receptors such as the TRPV1 receptor in the skin is identified as a key reason why blood vessels dilate excessively and inflammation develops even with minor stimuli. This bears a striking resemblance to the process in the Donguibogam where heat toxin surges upward and causes blood heat stagnation. External stimuli such as ultraviolet radiation, stress, hot or spicy food, alcohol, and rapid temperature changes stimulate cutaneous nerves, causing capillaries to dilate and resulting in repeated facial redness. It behaves just like internal heat toxin worsening in response to external heat. Furthermore, microbial factors such as demodex mites living on the skin or Helicobacter pylori in the stomach are also considered to influence the development and worsening of rosacea. This connects naturally with the concept in the Donguibogam where damp-heat drives toxins upward from the interior to the skin. A chronic inflammatory response damages the skin barrier and makes it more sensitive, causing it to flush easily and sting even with minimal irritation. While it begins as intermittent flushing in early stages, leaving it unmanaged may lead to permanent vasodilation, papules, and pustules. In severe cases, it can progress to strawberry nose where the shape of the nose alters, making early diagnosis and care essential. Modern medicine manages rosacea through various methods such as topical formulations, oral medications, and laser therapy, but there are often limitations in controlling the root causes of neurovascular regulation abnormalities and inflammatory responses. Therefore, an integrative approach that applies the insights of the Donguibogam to clear heat toxin inside the body and improve daily habits can be helpful.
