I have new blemishes after my vacation. What kind of treatment should I get?

Hello, I am a male office worker.

I recently went on a summer vacation where I spent a few days outdoors exercising and enjoying the ocean. Even though I tried my best to apply sunscreen, my skin got really tanned.

The problem is not just that I’ve gotten a tan; I can clearly see dull blemishes and age spots suddenly appearing on my cheeks and around my eyes that weren't there before. I am a man who usually only applies toner and lotion and has never been to a dermatologist. However, my face looks so messy every time I look in the mirror, so I plan to take this opportunity to get some dermatological treatment.

For those like me who developed blemishes after getting a severe tan from outdoor activities, what kind of treatments or toning care do people commonly receive at dermatology clinics? I am also curious if the results are very noticeable during daily life or when going to work.
