What should you know about skin sebaceous hyperplasia?

The bumps are usually flesh-coloured or yellowish and may have a small central dip. They often occur on the forehead, cheeks, nose or chin, and several can appear together. They are generally smooth and firm rather than sore, although rubbing or picking can irritate them. Sebaceous hyperplasia is different from acne, milia and some skin cancers, so a clinician may examine a new or uncertain bump before treatment.

If the appearance is not troubling, gentle cleansing and daily sun protection are reasonable skin-care measures. Do not squeeze, scrape or burn the bumps at home. A dermatologist can discuss options such as Electrosurgery or CO2 Laser Resurfacing when removal is wanted; choice depends on the number, depth, location and your skin type. A treated area may be red or crusted while it heals, and more than one session may be considered.

Arrange a skin assessment if a bump grows quickly, bleeds without being injured, develops a persistent sore, becomes distinctly darker, or looks unlike your other bumps. Seek prompt care for spreading redness, marked swelling, pus or increasing pain after a procedure. These changes do not identify one diagnosis by themselves, but they should not be self-treated.

Ask whether the appearance is typical of sebaceous hyperplasia, whether an examination or biopsy is needed, which removal method suits your skin, and how to care for the area while it heals.
