I am curious about the effectiveness of laser treatment for melasma and age spots before my vacation.

I am paying close attention to my skincare ahead of my vacation, but I am very worried because melasma and age spots have appeared on the sides of my cheeks and seem to be spreading. They are difficult to cover even with makeup, making my complexion look dull and older, which is causing me significant stress. I am considering getting laser treatments at a dermatology clinic, and I have heard about methods such as Pico Toning, IPL, and Laser Toning. I am curious to know how effective treatments have been for those who have actually undergone them. I would like to know if they noticeably fade after just one or two sessions, or if I need at least 3 to 10 sessions to see significant changes. I am also curious about the redness and recovery period after the procedure, as well as whether melasma and age spots frequently recur over time. Sharing your experiences or advice would be of great help.
