"My skin is so dry and itchy." Many people say this constantly. Especially during seasonal changes or winter, cracked skin and flaking cause great discomfort. While many think it's just dryness and try moisturizing, if symptoms persist and worsen, "psoriasis" should be suspected. Psoriasis is different from simple skin dryness in its causes and progression, making accurate diagnosis and proper treatment crucial.
💡 Key Answer Top 3 causes of "excessively dry and itchy skin": ① Environmental factors (dry air, frequent bathing) / ② Weakened skin barrier function / ③ Immune system disruption (primary cause of psoriasis) Dalimchae Clinic uses gut detox and constitutional improvement to resolve the root causes of skin inflammation and prevent recurrence.
How to distinguish skin dryness from psoriasis?
While they may appear similar, they differ significantly in cause, progression, and symptoms. Simple dryness is caused by external factors like dry air, reducing skin moisture. It primarily involves itching and flaking, which can improve with proper moisturizing.
Psoriasis, however, is a chronic inflammatory skin disease caused by immune system abnormalities. Skin cells proliferate and shed 10 times faster than normal, leading to layers of silver-white scales and red spots (erythema). It often appearing on friction-prone areas like elbows and knees, and tends to expand or cycle through worsening and improvement. Many patients in Incheon initially dismiss it as simple dryness before seeking specialized care.
Why does psoriasis occur? Skin is a mirror of the body.
Psoriasis is not just a surface issue; it's deeply linked to immune disruption, genetics, environment, stress, and gut health. In Korean medicine, the skin is viewed as an organ connected to the internal organs, reflecting internal imbalances.
Recent research on the "Gut-Skin Axis" shows that the gut, housing 70% of immune cells, significantly impacts skin health. Imbalances in gut microbiota cause systemic inflammation. When the gut lining is damaged (leaky gut syndrome), toxins enter the bloodstream, reaching the skin and triggering hypersensitive immune responses that worsen psoriasis. Therefore, treatment must improve the gut environment and restore immune balance.
Korean medicine improves the quality of life for psoriasis patients.
Psoriasis requires long-term management. Korean medicine addresses the root causes—internal heat, toxins, and immune imbalance. In Incheon, we use herbal medicine and acupuncture to reduce inflammation and aid skin regeneration.
A 2022 meta-analysis of 4,966 patients published in MDPI reported that East Asian Herbal Medicine (EAHM) was superior to placebos in improving psoriasis lesions. Significant improvements were seen in PASI 70 (p < 0.0001) and PASI 60 (p < 0.0001) scores, as well as inflammatory markers like IL-17 and TNF-α. Researchers concluded EAHM is effective for managing inflammatory lesions with low side effects.
Furthermore, a 2025 study in 'Phytotherapy Research' identified that natural products inhibit inflammatory signaling and abnormal skin cell growth, aligning with Dalimchae Clinic's multifaceted approach.
