Eczema and Psoriasis Do Not Get Confused Real Causes and Distinction of Skin Diseases

Red rashes, unbearable itchiness, white exfoliating dead skin... When abnormal signs appear on the skin, we often think of it as 'dermatitis' or 'eczema' and easily brush it off. However, among those who suffer from chronic skin concerns, did you know that symptoms previously considered simple eczema might actually be psoriasis? Although the two conditions look similar, their causes and treatment approaches are completely different, making accurate distinction crucial.

💡 [Key Answer] 3 most common causes of eczema and psoriasis questions: ① Immune system imbalance: Excessive or malfunctioning immune responses cause skin inflammation. ② Gut health abnormalities: Toxins in the gut travel through the blood throughout the body, worsening skin inflammation. ③ Skin barrier damage: Vulnerability to external stimuli leads to frequent inflammatory reactions and chronicity. Dalimchae Korean Medicine Clinic relieves the root cause of skin inflammation through gut detoxification and constitution improvement, helping your skin regain its natural regenerative power.

Eczema and psoriasis are both chronic inflammatory skin diseases accompanied by red spots, itchiness, and dead skin, but they show important differences in their pathogenesis and clinical manifestations. Eczema is a general term for dermatitis caused by various factors such as external stimuli, allergic reactions, or internal immune imbalance, initially accompanied by exudate or edema, and over time causing skin thickening or scaling. On the other hand, psoriasis is an autoimmune disease caused by abnormal rapid proliferation of skin cells due to immune system abnormalities, characterized by well-demarcated red plaques covered with thick silvery-white scales. It particularly frequently appears on friction-prone areas such as elbows, knees, buttocks, and scalp, and while itchiness is less severe than eczema, skin cracking can cause pain. Because these two conditions share overlapping symptoms, distinguishing them accurately with the naked eye can be difficult, and misdiagnosis can lead to missing appropriate treatment timing.

Dalimchae Korean Medicine Clinic views eczema and psoriasis not merely as skin problems, but as the result of internal bodily imbalances manifesting on the skin. In particular, focusing on the close connection between the immune system and gut health, we place emphasis on managing the root causes of skin inflammation.

In Korean medicine, eczema is treated by dividing it into various pattern identifications such as 'Damp-Heat (濕熱)', 'Blood Deficiency (血虛)', and 'Wind-Heat (風熱)', while psoriasis is diagnosed as 'Blood-Heat (血熱)', 'Blood-Dryness (血燥)', or 'Blood Stasis (血瘀)', applying customized prescriptions suited to each constitution and symptom. The core is to expel toxins and waste accumulated inside the body, strengthen skin immunity, and create an environment where the skin can regenerate on its own.

A meta-analysis study published in the MDPI journal in 2022 revealed that oral herbal medicine administration is effective in improving skin symptoms in psoriasis patients. Analyzing 29 randomized controlled trials (total 2,479 patients), this study confirmed that East Asian Herbal Medicine (EAHM) monotherapy was statistically significantly superior to conventional Western medical treatment (CM) or placebo in 60% improvement rates of Psoriasis Area and Severity Index (PASI) (RR: 1.1923, 95% CI: 1.1134–1.2769, p < 0.0001). Especially in the PASI 70% improvement rate, 18 studies (total 1,865 patients) showed statistically significant improvement in the East Asian herbal medicine treatment group compared to the Western medical treatment group (RR: 1.2845, 95% CI: 1.1906–1.3858, p < 0.0001). The researchers concluded that these results are due to the effect of herbal medicine acting as multi-targets on multiple immune pathways such as inflammatory cytokines (IL-17, IL-23, TNF-α) to suppress skin inflammation.

In addition, a study by the research team of Professors Lee Dong-heon and Cho Hee-geun of Gachon University published in 'Autoimmunity Reviews' in 2025 scientifically proved through network pharmacology analysis and experimental verification that herbal medicines and natural product components are effective in treating psoriasis, and specifically act in a 'multi-target treatment' manner regulating major inflammatory response pathways such as IL-17/IL-23, MAPK, and NF-kB. This suggests that Korean medical treatment can become a new alternative for psoriasis, a chronic inflammatory skin disease.

Based on these research data, Dalimchae Korean Medicine Clinic understands skin not just as an organ but as a mirror of the whole body, applying treatment principles that improve internal causes.

For fundamental treatment of skin diseases, Dalimchae Korean Medicine Clinic pays attention to gut detoxification treatment. Our body's gut goes beyond a simple organ responsible for digestion, being closely related to the immune system as 'the second brain' where more than 70% of immune cells exist. If gut health is poor, intestinal barrier permeability increases ('leaky gut syndrome'), and harmful substances or toxins in the gut travel through the blood throughout the body, inducing or worsening skin inflammation reactions. This becomes the cause of various chronic skin diseases such as atopic dermatitis, eczema, and psoriasis.

Dalimchae Korean Medicine Clinic's gut detoxification treatment aims to remove bodily waste and toxins, restore the balance of beneficial gut bacteria, and strengthen barrier function. Through this, we reduce hypersensitivity reactions of the immune system and improve the skin's regenerative capacity, preventing inflammation from becoming chronic. Many people looking for Songdo eczema Korean medicine and Songdo psoriasis Korean medicine are experiencing overall condition improvement as well as skin symptoms through gut detoxification treatment.

Q. Why do eczema and psoriasis worsen in winter? A. Winter season easily weakens skin barrier function due to dry weather and low temperatures. Because of this, skin becomes more sensitive to external stimuli, and skin moisture loss accelerates, easily worsening eczema and psoriasis symptoms.

Q. Can eczema or psoriasis be fundamentally treated with Korean medicine? A. Yes, it is possible. Korean medicine improves not only symptoms appearing on the skin but also internal bodily imbalances, especially issues with gut function and immune system, helping the skin build the power to recover and regenerate on its own. Consistent Korean medicine treatment can help lower recurrence rates and maintain amazing skin health.
