Sebaceous hyperplasia is a common, benign condition of sebaceous glands in adults of middle age or older. It’s a harmless skin disorder of the sebaceous (oil) glands, where the sebaceous gland becomes enlarged. These harmless bumps often appear soft, yellowish in colour with a cauliflower-like or donut-shaped appearance ranging in size from 2 to 3mm. They usually appear on the forehead and cheeks in fair-skinned people who have dealt with oily or combination skin over the years.
Sebaceous hyperplasia is the term used for enlarged sebaceous glands seen on the forehead or cheeks of the middle-aged and elderly leading to an ongoing problem with over-productive oil glands. They appear to be somewhat indented in the middle. This indented centre is characteristic of sebaceous hyperplasia. It has nothing to do with milia or an old spot.
