How many days is the best cycle for Pico Toning, the blemish eraser?

After returning from a late vacation to Southeast Asia last month, my melasma and freckles had really deepened. Sigh...

My partner and I poured whitening ampoules on ourselves, but it didn't work, so I finally stopped by Maypure after work a few days ago and splurged on a 10-session Pico Toning package. I have high hopes because I heard it's less painful than regular toning and breaks down pigmentation faster. Is the standard interval for this treatment usually how often should I get it? The director told me to come every 1-2 weeks, but I'm worried that if I schedule it tightly once a week just to get rid of the pigmentation quickly, it might strain my skin barrier. If any of you members who are consistently getting treatments have your own tips for the optimal schedule, please let me know! I plan to keep going diligently until the day my complexion becomes clear!
