Dark forehead pores

Lately, I have been concerned because my forehead skin looks messy and not smooth overall. If I look closely, I can see small bumps, and since I tend to get sebum quickly, my face doesn't feel refreshed even after washing. It bothers me particularly because the bumpy areas are more visible under lighting. I have tried exfoliating and using sebum control products at home, but they seem to improve for a while before coming back in a similar state. I know it is bad to touch or squeeze them, so I am trying my best not to touch them. I am wondering if this forehead skin condition is simply due to sebum or dead skin cells, or if it could be milia or another skin issue. Could a dermatologist examine my forehead to identify the cause? If I receive treatment, I would like to ask the clinic staff how to manage the condition and what precautions I should take at home.
