(Concern) Adult acne is really stressful.

Hello, I am stressed about my acne-prone skin during this event. I didn't usually have much acne, but for the past month, I've been getting a lot of pimples only on my forehead. They are bumpy and raised, and it's not even allergy season, so it's really stressful. I don't know why this is happening suddenly, which makes me even more frustrated. When I look in the mirror, I only see a faint reflection, but even after some time, the pimples don't easily go away, and it seems like they are spreading more. Would it be best to visit a dermatologist for treatment?
