Sebaceous hyperplasia primarily affects older patients in areas with high concentrations of sebaceous glands, such as the face, head, and neck. [3] It typically manifests as yellowish-colored skin with small papules that are often surrounded by telangiectatic blood vessels, also known as "crown vessels," and a central dell that is in line with the origin of the lesions, which is a dilated ...
Doctors do not agree on what causes cradle cap, but the two most common hypotheses are fungal infection and overactive sebaceous glands. Cradle cap is an inflammatory condition. [4] Possibly it has to do with overactive sebaceous glands in the skin of newborn babies, due to the mother's hormones still in the baby's circulation. The glands ...
In some people, however, these sebaceous glands become overactive, producing more sebum than necessary, leading to an oily scalp and hair that gets greasy quickly. There are a few different causes ...
Isotretinoin, a sebosuppressive agent, may be used to reduce sebaceous gland activity as a last resort in refractory disease. [29] However, isotretinoin has potentially serious side effects, and few patients with seborrhoeic dermatitis are appropriate candidates for therapy.

Two dermatologists explain the difference between sebaceous filaments and blackheads and share the 8 best tips for getting rid of sebaceous filaments at home.
A subset of those affected by acne rosacea go on to develop rhinophyma. Chronic infection is common as the thickened sebaceous fluid traps bacteria. [2] Rhinophyma is characterised by hypertrophy of nasal skin, with hyperplasia and fibrosis of the sebaceous glands and connective tissue.
Sebaceous glands are part of the body's integumentary system and serve to protect the body against microorganisms. Sebaceous glands secrete acids that form the acid mantle. This is a thin, slightly acidic film on the surface of the skin that acts as a barrier to microbes that might penetrate the skin. [20]
Occasionally, several adjacent glands will coalesce into a larger cauliflower-like cluster similar to sebaceous hyperplasia of the skin. In such an instance, it may be difficult to determine whether or not to diagnose the lesion as sebaceous hyperplasia or sebaceous adenoma. The distinction may be moot because both entities have the same ...
