I have more freckle-like blemishes on the bridge of my nose and cheeks. What should I look for first during the consultation?

Lately, when I look closely in the mirror, I notice that there are more small, brown spots resembling freckles on the bridge of my nose and upper cheeks than before. Even though I made sure to apply sunscreen all summer, they seem to have become more distinct now that late autumn has arrived, so it is bothering me. Even when I try to cover them with makeup, the spots on my nose wear off quickly, so they reappear by the afternoon. I am looking into laser treatments, but there are so many types that I don't really know where to start for a consultation.

1. What criteria do you use to distinguish between freckles and melasma during a consultation?

2. Do I manage oily areas like the bridge of the nose in the same way as the cheeks?

3. If redness or scabs form after the procedure, to what extent is it possible to resume daily activities, such as going to work?

4. What should I pay attention to on a daily basis to prevent it from becoming darker again in the spring after managing it in the winter?

I attached the photo below for reference because it feels similar to my concerns.
