What is a skin condition caused by chronic inflammation of the sebaceous glands?

Seborrheic dermatitis is a skin condition resulting from chronic inflammation of the sebaceous glands. This condition is characterized by redness, flaky scales, and greasy patches, often occurring on areas of the body that have a high density of sebaceous glands, such as the scalp, face, and upper body.

The inflammation in seborrheic dermatitis is typically associated with an overgrowth of Malassezia yeast, which thrives in the oily environment created by the sebaceous glands. This inflammatory response leads to the symptoms, which can be exacerbated by factors such as stress, hormonal changes, and environmental conditions. Treatment may focus on reducing inflammation and controlling the growth of yeast, often through topical antifungals or anti-inflammatory medications.

Other conditions such as psoriasis, acne, and eczema have different underlying causes. Psoriasis is primarily an autoimmune condition that causes rapid skin cell turnover, leading to thickened, silvery plaques. Acne involves the blockage of hair follicles and can be influenced by hormonal factors and bacteria. Eczema, or atopic dermatitis, is primarily linked to an immune response and often involves dry, itchy skin rather than the oily, inflamed patches seen in seborrheic dermatitis.
