Will my acne marks fade a bit before my vacation? I am considering a procedure.

I don't get as much acne as I used to, but I'm stressed because the red marks and light pigmentation keep lingering. Since I plan to take a lot of photos and go around without makeup during this vacation, I want to make my skin as clear as possible.

If I start taking care of my skin now, will it improve even a little? I have about a month left until my vacation, and I'm wondering if there are any treatments that can show results within this timeframe. I'm a bit hesitant about Fraxel because I heard the recovery period is long, and while laser toning and V-Beam are highly recommended, I'm not sure what the differences are.

My skin is on the sensitive side, so I'm a bit worried about procedures that are too irritating. Also, since I'll be wearing makeup while traveling, I want to avoid excessive peeling or scabbing. If anyone has had similar concerns and tried skincare before their vacation, please share a review of what treatment you received and how satisfied you were.
