Sebaceous hyperplasia is characterized as a benign lesion that arises from dilated sebaceous glands, often appearing as small, soft, yellowish bumps on the skin. These lesions are most commonly found in areas of the face that have a higher concentration of oil glands, such as the forehead, nose, and cheeks. Its formation is usually associated with increased oil production and can often be mistaken for other types of acne or lesions due to their appearance. This benign nature means that sebaceous hyperplasia typically does not pose any health risks and is not linked to any inflammatory processes, making it different from conditions such as acne vulgaris, which involves inflammation and can lead to more severe skin issues. While keratosis and milia have their own characteristics and locations on the skin, they do not specifically relate to the oilier regions nor are they directly correlated to the activity of sebaceous glands like sebaceous hyperplasia.
