What kind of treatment would be good for dull skin after returning from vacation?

My skin hasn't been the same since I got back from vacation...

I spend a lot of time outdoors, so even though I've been diligently applying sunscreen, my face looks dull overall and my blemishes seem to have gotten a bit darker. I am particularly concerned about the freckles and pigmentation on my cheekbones, and my skin texture feels rougher. My makeup usually applies well, but lately it tends to cake a lot, which is a concern.

I have been taking care of my skin at home with face masks and whitening cosmetics, but I haven't really noticed any significant changes yet. So, I am thinking about getting a dermatological procedure this time. I would like recommendations for treatments that can improve both pigmentation and skin tone. I have seen a lot of talk about procedures like Pico Toning and Revicol, and I am curious to know which skin concerns each is best suited for.

I would like to know how many sessions are required to see results and how long the recovery period is. Since I work, I would prefer a procedure that does not significantly interfere with my daily life. If there is a procedure that satisfied those who were concerned about dull skin or melasma after a vacation, please share your experience as well.
