Why Seborrheic Dermatitis Doesn't Heal Well

Hello, this is Baekrokdam Korean Medicine Clinic. Today, we'll be discussing seborrheic dermatitis. If you have any other questions, please leave a comment.
What is Seborrheic Dermatitis?
Seborrheic dermatitis is a common inflammatory skin condition that primarily affects areas rich in sebaceous glands (oil glands). While it can appear on various parts of the body, it most commonly affects the scalp, face, and chest.
Although the exact cause of seborrheic dermatitis is not fully understood, various factors contribute to its development. It is characterized by red, itchy, and scaly skin. It often appears as flaky, yellowish, and greasy scales. The severity of symptoms varies; some individuals experience only mild discomfort, while others may suffer from more persistent and bothersome symptoms.
Symptoms of Seborrheic Dermatitis
- Redness: Affected areas may become red and inflamed.
- Itching: Skin itching is a common symptom, and scratching can worsen the condition.
- Skin Flaking: White or yellowish scales may appear on the skin, particularly prominent in areas with dense sebaceous glands.
- Oily or Greasy Skin: Increased sebum production can lead to oily or greasy skin.
Causes
The exact cause of seborrheic dermatitis is unknown, but several factors are thought to contribute:
- Malassezia: Malassezia is a type of yeast naturally present on the skin. Its overgrowth is associated with seborrheic dermatitis.
- Genetics: Seborrheic dermatitis often runs in families, suggesting a genetic predisposition.
- Hormonal Factors: Hormonal changes, such as those occurring during puberty or in conditions like Parkinson's disease, can influence the development of seborrheic dermatitis.
- Neurological Conditions: Certain neurological disorders, such as Parkinson's disease or impaired immune systems, can increase the risk of seborrheic dermatitis.
- Stress and Fatigue: Emotional stress and lack of sleep can contribute to the onset of seborrheic dermatitis or worsen existing symptoms.
- Certain Health Conditions: Individuals with certain conditions like HIV/AIDS or psoriasis may be more susceptible to seborrheic dermatitis.
Differentiating from Other Skin Conditions
Dermatitis (eczema) is a general term referring to inflammation of the skin, and there are various types of dermatitis. The following summarizes the differences between seborrheic dermatitis and other types of dermatitis.
| Condition | Symptoms | Causes |
|---|---|---|
| Seborrheic Dermatitis | Red, itchy, flaky skin with yellowish or greasy scales | Overgrowth of Malassezia yeast, genetic predisposition, hormonal changes, stress, certain medical conditions, etc. |
| Atopic Dermatitis | Itchy, red, inflamed skin that is dry, cracked, and sometimes weeping | Genetic predisposition, immune system dysfunction, environmental factors, triggers such as allergens |
| Contact Dermatitis | Redness, itching, rash at the site of contact | Exposure to irritants or allergens like soaps, cosmetics, plants, or metals |
| Nummular Eczema | Itchy, distinct circular or oval lesions with redness, scaling, and crusting | Exact cause unknown, but associated with dry skin, environmental factors, or a reaction to skin injury |
| Dyshidrotic Eczema | Itchy blisters on the palms, fingers, and soles of the feet | Genetic factors, exposure to allergens or irritants, stress |
Seborrheic Dermatitis and Skin Barrier Function
The skin barrier plays a crucial role in protecting the body from external factors, preventing moisture loss, and maintaining overall skin health. Here's how seborrheic dermatitis affects the skin barrier:
- Inflammation and Disruption: Seborrheic dermatitis is characterized by inflammation of the skin, which can compromise the integrity of the skin barrier. The inflammatory process can disrupt the normal function and interaction of skin cells.
- Increased Sebum Production: Seborrheic dermatitis often involves an overgrowth of Malassezia yeast, especially in areas with dense sebaceous glands. This overgrowth can stimulate sebum (skin oil) production. Excessive sebum can alter the composition of surface lipids and affect barrier function.
- Altered Skin Microbiome: The presence of Malassezia, the yeast associated with seborrheic dermatitis, can affect the skin microbiome. Changes in the microbiome can impact the balance of skin microorganisms and potentially lead to barrier dysfunction.
- Skin Barrier Dysfunction: The outermost layer of the skin, known as the stratum corneum, is a crucial component of the skin barrier. In seborrheic dermatitis, changes can occur in the stratum corneum, including increased desquamation (shedding of skin cells) and abnormal keratinization. These alterations can impair the epidermal barrier.
- Itching and Scratching: Skin itching is a common symptom of seborrheic dermatitis. Persistent itching leads to scratching, and excessive scratching can further damage the skin barrier. Scratching can create micro-tears in the skin, making it more vulnerable to irritation and potential infection.
- Dryness and Flaking: The condition often manifests as dry, flaky skin. Dry and flaky patches may indicate inadequate hydration and a compromised skin barrier.
Traditional Korean Medicine Treatment for Seborrheic Dermatitis
Chronic and recurrent skin symptoms are often the result of abnormal systemic changes in the body. This is why simply applying ointments to the affected skin area often doesn't resolve the issue and leads to recurrence. Treatment for chronic skin conditions should be carried out by considering various factors, such as those listed below:
- Alleviation of localized skin symptoms such as itching and inflammation of hypersensitive skin
- Restoration of skin barrier function
- Restoration of the skin's normal microbial ecosystem
- Normalization of the systemic immune system
In Korean medicine dermatology treatment, we set the above treatment goals and proceed with therapy using Korean herbal medicine (hanbang-yak), acupuncture (chim), moxibustion (tteum), herbal compresses (seuppo), and herbal ointments (hanbang-yeon'go). If you are suffering from long-standing seborrheic dermatitis, we hope this gives you an opportunity to consider traditional Korean medicine treatment.
