How satisfied are people with dermatology treatments for blemishes?

I am an office worker who is worried because the number of age spots and freckles on my face has increased significantly lately.

I get stressed every time I look in the mirror, so I'm thinking of getting some treatments. I'm writing this post because I'm curious about the actual satisfaction level after blemish treatments.

Although everyone has different skin types, people generally say that your complexion looks much brighter once large blemishes disappear.

However, are there cases where satisfaction with the blemish treatment drops due to side effects, such as the spots reappearing quickly or leaving scars? As I am considering the procedure, I would appreciate your advice on which laser to choose to ensure high satisfaction.
