Today, some small bumps appeared on my face. They're not particularly itchy or painful. A friend suggested it might be seborrheic dermatitis. Could you please explain what causes this condition?

It is immune-related, an immunological disorder that causes organ damage within the body. Therefore, we currently adopt a combined approach using anti-androgen medications and immunotherapy for seborrheic dermatitis. Some people habitually consume greasy foods, or prefer spicy, irritating, and high-sugar foods. These foods can easily cause digestive dysfunction and endocrine disorders, strongly irritate the skin, and trigger seborrheic dermatitis.
