What should a man consult first when visiting a dermatologist for the first time?

I hadn't been taking care of my skin much, but recently when I looked in the mirror, I started to get really bothered by my pores and skin texture.

In particular, the area where I shave often turns red, and I repeatedly get breakouts on my chin. Until now, I've just been washing my face and applying an all-in-one product, but now I want to try managing my skin properly.

What should I discuss when visiting a dermatologist for the first time? I am curious about men's experiences with their first skincare treatments.
