Remarkably, modern medicine is scientifically validating the insights of Donguibogam. The concept known as the gut-skin axis is a prime example, with a flood of recent studies showing just how closely gut health and skin health are linked.
Inside our gut lies a microbiome ecosystem where countless microorganisms reside. When this microbial balance is disrupted—that is, when gut dysbiosis occurs—problems begin. When harmful bacteria multiply and beneficial bacteria decline due to sugar, processed foods, stress, and other factors, leaky gut syndrome can develop as the barrier function of the intestinal mucosa weakens.
When the intestinal barrier loosens, undigested food debris and toxins produced by harmful bacteria, such as the endotoxin lipopolysaccharide, penetrate into the bloodstream. These toxins circulate throughout the whole body and trigger chronic inflammation, and because the skin is the largest organ in our body, it is exceptionally vulnerable to this inflammation. Inflammatory substances that reach the skin through the blood abnormally stimulate sebaceous gland activity and induce inflammation around hair follicles, becoming primary culprits behind acne and breakouts. Furthermore, research findings continue to demonstrate that gut health plays a key role in various skin conditions such as atopic dermatitis, psoriasis, and rosacea.
In particular, when bowel movements are not smooth and constipation occurs, the prolonged exposure of our body to waste and toxins in the intestines increases the risk of more toxins being absorbed into the blood. This can lead to a vicious cycle that aggravates skin troubles. With the introduction of the gut-brain-skin axis concept, which describes how the gut, brain, and skin exchange signals with one another, it has also been revealed that stress impairs gut function, which can worsen skin problems. Modern science clearly shows that the key to resolving skin concerns that topical cosmetics alone could not fix lies within a healthy gut.
