When explaining our body's wondrous harmony from a modern medical perspective, upper heat and lower cold can largely be explained by an imbalance of the autonomic nervous system and the endocrine system. Adult acne or breakouts occurring repeatedly around the jawline can be seen as warning signals sent by our body's core systems, going beyond simple skin troubles.
First, we can consider autonomic nervous system imbalance. Chronic stress excessively activates the sympathetic nerve, putting our body into tension mode. When the stress hormone cortisol is continuously secreted, sebum secretion can increase in the skin and inflammatory responses can be promoted. At the same time, stress tends to constrict peripheral blood vessels, making the hands, feet, or lower abdomen cold. This is similar to the state of the lower burner becoming cold described in Donguibogam, triggering a mechanism that obstructs the body's heat circulation and drives heat toward the upper body. That is, stress affects the autonomic nervous system to induce symptoms similar to upper heat and lower cold, which can subsequently manifest as inflammatory acne around the jawline.
Second, hormonal imbalance is also an important cause. Particularly in women, the menstrual cycle or endocrine diseases such as polycystic ovary syndrome (PCOS) can trigger excessive secretion of androgen. This androgen stimulates sebaceous glands to promote excessive sebum production and increases keratin inside hair follicles, worsening acne. The jawline is known to be an area that reacts sensitively to hormonal changes because it has relatively many androgen receptors. Furthermore, high-carbohydrate and high-fat diets that cause blood sugar spikes can elevate insulin resistance and further increase androgen activity. This also aligns with the context of problems arising from impaired metabolism and circulation of food, or what Donguibogam refers to as fluids of water and grain.
Third, the importance of the gut-skin axis cannot be overlooked. When intestinal health is poor, the intestinal barrier weakens, potentially leading to leaky gut syndrome, where harmful substances enter the bloodstream. This induces a systemic inflammatory response and can affect the skin, exacerbating inflammatory diseases such as acne. In Korean medicine, diminished function of the lower burner can be viewed as a state where digestion, absorption, and excretion functions are not smooth, causing waste to accumulate and cold qi to circulate within the body, which also connects to gut health issues in modern medicine.
In conclusion, breakouts around the jawline are not simply a surface skin problem, but can be understood as a signal of chronic inflammation created by complex imbalances in our body's autonomic nervous system, endocrine system, and digestive system. It is important to borrow the wisdom of Donguibogam to understand our body's signals, grasp the causes more deeply through modern medical explanations, and restore the body's balance in the proper way.
