Seborrheic dermatitis causes overproduction of skin cells and sebum or the skin's natural oil. It usually occurs in areas of the body that have many oil-producing glands, including the scalp, face, more specifically on the eyebrows, the bridge and sides of the nose, and in the crease between the nose and lip . The cause of seborrheic dermatitis is not completely clear but may be associated with overgrowth of a normal skin fungus.
There is no specific test for diagnosing seborrheic dermatitis. The diagnosis is usually based upon a person's history and physical examination. The symptoms of seborrheic dermatitis can be effectively controlled with a combination of self-care measures and drug therapy.Diligent washing or shampooing can control the symptoms of seborrheic dermatitis by countering the build-up of skin scales. Low potency topical glucocorticoids are usually recommended first for the treatment of seborrheic dermatitis. These treatments are available in creams and lotions for the face. The topical steroid should be applied daily until the dermatitis improves; they can then be gradually discontinued.
If it persists, it would be best to see your dermatologist for further evaluation and management. Take care and keep us posted.
Quote: The bumps have never itched, burned, peeled, excreted any fluid or anything like that.
As an SD sufferer and constant SD researcher, it doesn't sound like Seborrheic Dermatitis. That being said, you should be seen by a Dermatologist if the bumps are spreading.
