This is my first time getting a dermatological procedure. Would it be okay if I got a skin diagnosis first before making a decision?

Lately, I feel like the pores, skin texture, and oil-moisture balance around my nose and cheeks have changed compared to before, so I am thinking about getting dermatological treatments for the first time. However, when I look up the names of the procedures online, they all look good and the descriptions are similar, so I'm not sure what my skin actually needs.

I visited with a specific procedure in mind, but I'm concerned it might not be suitable for my skin, so if possible, I would like to have my skin condition checked first.

Is it okay if I don't decide on the procedure I want to receive in advance when I visit for the first time?

I would like to have my nose and cheeks checked for oiliness, dryness, pores, and skin texture, and then receive recommendations on the areas I should prioritize taking care of right now.

Rather than undergoing multiple procedures from the start, I would like to begin with one that is less burdensome and manage my skin while monitoring its reaction.
