(Question) What treatment is suitable for sudden breakouts of acne?

I have a lot of worries these days because I suddenly have a lot of acne on my forehead.

My skin isn't usually sensitive, but recently, small, bumpy pimples have been popping up only on my forehead.

I've also been getting a lot more red bumps that look like inflammation. I haven't changed any cosmetics or facial cleansers.

It doesn't seem like my lifestyle has changed much, so I don't know why this is suddenly happening.

I feel even more frustrated because I don't know the cause—whether it's my bangs or my sebum.

I'm planning to visit a dermatologist, and I'm wondering which treatment would be the most effective in this case.

I would like to know if extraction or scaling alone is sufficient, or if I need to receive laser or acne management treatments as well.

For those of you whose forehead acne suddenly worsened, please share reviews on how you managed it.
