What is sebaceous hyperplasia?
This refers to the development of small raised white or skin-coloured lesions on the forehead or central face. These develop in individuals with a greasy skin (seborrhoea) and are due to excessive collections of grease and skin cells. They are typically 1-3mm in size and may resemble a type of skin cancer called basal cell carcinoma.

Is treatment necessary?
Sebaceous hyperplasia is not harmful and treatment is only necessary if the skin lesions cause cosmetic embarrassment. Occasionally, a small skin sample may need to be taken to exclude a skin cancer. This can be taken by scraping the skin (curettage) or by a punch biopsy involving stitches.
Topical Retinoid Cream or
Topical retinoids act on retinoid receptors in the surface skin cells to reduce grease production and this may help prevent sebaceous hyperplasia from developing. It is not particularly effective for treating skin lesions that have already developed. In severe cases, oral therapy with isotretinoin (Roaccutane) may be necessary.
