There are many causes of raised bumps in the eyebrows, the common ones are: acne, boils, sebaceous cysts, viral warts, etc. 1. Acne: It is related to androgen-induced increase in follicular secretion, hyperkeratosis of the hair follicle, and propagation of Propionibacterium acnes, which may lead to raised bumps in the eyebrows. 2. Boils: purulent infections of the hair follicles and surrounding tissues, which can also lead to subcutaneous nodules in the early stages, may also cause raised bumps in the eyebrows. 3. Sebaceous cysts: Blockage of sebaceous ducts can cause retention of secretions, resulting in a raised bump on the eyebrow. 4. Viral warts: Flat warts and common warts caused by human papilloma virus infection can also cause bumps in the eyebrows. There may be other reasons for this, so it is recommended that you go to the hospital and get a clear picture of the cause of the problem and get a standardized treatment under the guidance of your doctor.
