Hello. This is Dalimchae Korean Medicine Clinic.

My skin keeps itching and breaking out. How can I tell the difference between simple eczema and psoriasis?

When confused between eczema and psoriasis, it's a common concern for many. You must have felt frustrated by the persistent itching that keeps you awake at night, the red rashes that pop up, and the unsightly dead skin cells. It's even more tiring if it's hard to get a clear diagnosis at a dermatologist or if chronic skin troubles only improve temporarily after applying steroid ointments. These chronic skin problems often start not from simple external stimuli, but from fundamental imbalances within our bodies.

💡 [Key Answer] The 3 most common causes for when you're confused whether it's simple eczema or psoriasis: ① Immune system disruption: Immune balance is broken due to deteriorating gut health, etc., leading to excessive skin inflammatory responses. ② Weakened skin barrier function: The skin's defensive function to block the penetration of external harmful substances and prevent moisture loss drops. ③ Chronic inflammatory response: Skin regeneration ability is hindered due to accumulation of toxins in the body and decreased blood circulation. Dalimchae Korean Medicine Clinic removes toxins in the gut through gut detox and restores immune balance to strengthen the skin's inherent defensive power.

Symptoms such as itching, rashes, and dead skin cells appearing on the skin can appear commonly in various skin diseases, making it very difficult for patients to make an accurate diagnosis themselves. In particular, eczema and psoriasis often show a chronic course and have similar patterns, making them even easier to confuse. However, since the two diseases differ in their onset mechanisms and treatment approaches, accurate differentiation is the first step toward proper treatment. Many patients first consider it a simple skin trouble and rely only on ointments before the symptoms become chronic and they visit Songdo Skin Disease Korean Medicine Clinic.

Eczema and psoriasis can be difficult to distinguish by symptoms visible to the naked eye alone, but they can be differentiated through several characteristic differences. Eczema is mainly accompanied by itching, erythema, discharge, and swelling, and if it becomes chronic, it shows lichenification, where the skin thickens and wrinkles. On the other hand, psoriasis is characterized by thick silvery-white dead skin cells piling up on red spots with clear boundaries. It appears well in areas with a lot of friction, such as elbows, knees, and the scalp, and sometimes spreads throughout the body.

These skin diseases are not just simple skin problems but are deeply related to our body's overall immune system. In particular, gut health and the skin are connected by the 'Gut-Skin Axis', similar to the 'Gut-Brain Axis', so an imbalance in the gut environment can cause or worsen skin inflammation.

According to a meta-analysis study published in 2024, evaluating the efficacy and safety of combined East Asian Herbal Medicine (EAHM) and narrow-band ultraviolet B (NB-UVB) treatment for psoriasis patients, analyzing a total of 40 randomized controlled trials (3521 participants) showed that combined EAHM treatment had statistically significantly superior improvement effects in major indicators such as the Psoriasis Area and Severity Index (PASI) score compared to NB-UVB alone. This suggests that herbal medicine treatment can play a positive role in regulating inflammatory responses and alleviating skin symptoms of psoriasis.

Also, in a systematic literature review study on herbal medicine treatment for atopic dermatitis published in 「Evid Based Complement Alternat Med」 in 2020, synthesizing a total of 9 systematic literature reviews and re-analyzing 58 randomized controlled trials confirmed that herbal medicine treatment significantly lowered the SCORAD (SCORing Atopic Dermatitis) score, increased the total effective rate, and was effective in improving atopic symptoms such as itching and sleep quality compared to placebo or Western medicine alone. This shows that Korean medical treatment can contribute to overall symptom alleviation and immune regulation even for atopic dermatitis, which is similar to eczema.

These research results align with the treatment philosophy pursued by Dalimchae Korean Medicine Clinic. At Dalimchae Korean Medicine Clinic Songdo Branch, we focus on empowering the skin to recover itself by resolving the body's fundamental imbalances, rather than simply suppressing the symptoms appearing on the skin.

The root cause of chronic skin diseases often stems from imbalances in our body's immune system, gut health, and autonomic nervous system. In particular, gut detox is one of the core treatment principles of Dalimchae Korean Medicine Clinic and plays an important role in the fundamental resolution of skin diseases. Toxins accumulated in the gut wall spread throughout the body through the blood, causing inflammatory responses, which can appear as various troubles on the skin. When gut health deteriorates, the defensive power of the gut mucosa, where more than 70% of immune cells reside, weakens, making it easier for harmful bacteria and toxins to penetrate, causing systemic inflammation and immune hypersensitivity reactions.

At Dalimchae Korean Medicine Clinic, we closely diagnose each individual's constitution, skin condition, and gut health status to help discharge harmful toxins in the gut and promote the growth of beneficial bacteria through customized herbal medicine prescriptions. This contributes to reducing inflammation of the gut mucosa and strengthening gut barrier function to block inflammatory signals leading to the skin. Additionally, herbal medicine helps soothe hypersensitivity reactions by regulating the immune system and promotes skin regeneration. This approach is effective in lowering the possibility of recurrence for when eczema and psoriasis are confused by creating a constitution where the skin can become healthy itself, rather than simple symptom suppression.

Many people looking for Songdo Eczema Korean Medicine Clinic knock on the door of Dalimchae Korean Medicine Clinic after feeling the limitations of the temporary effects of steroid ointments, which shows that skin diseases should be understood within the remarkable relationship with internal organs, not just as simple external problems. As the saying goes, the skin is a mirror of the body; it is important to solve the problems inside the body beyond the symptoms revealed on the outside. Songdo Psoriasis Korean Medicine Clinic Dalimchae Korean Medicine Clinic treats various skin diseases such as atopy and hives from this perspective and finds the balance of the whole body.

FAQ

Q. How are simple eczema and psoriasis different? A. Eczema is mainly characterized by itching, discharge, and swelling, and lichenification appears when it becomes chronic. Psoriasis is characterized by thick silvery-white dead skin cells piling up on red spots with clear boundaries and mainly occurs in friction areas.

Q. Why is the skin itching more severe at night? A. This is because the parasympathetic nervous system is activated at night, increasing blood flow to the skin, and as body temperature rises, the secretion of histamine, which causes itching, increases. Also, stress and fatigue from daytime activities can deepen the autonomic imbalance and amplify the itching.

Q. Can chronic skin diseases be fundamentally treated with Korean medicine? A. Yes, in Korean medicine, chronic skin diseases are not seen simply as a problem of the skin but are treated by integrating systemic immune imbalance, gut toxins, and blood circulation issues. By resolving the fundamental causes inside the body, we create an environment where the skin can become healthy itself, preventing recurrence and improving symptoms.
