Inquiry regarding the Maypure Pigmentation Package treatment cycle and post-procedure precautions

I have areas where I used to have severe breakouts that haven't healed completely and have left red, dark marks. Now that summer has arrived, the marks look even more prominent, possibly due to melanin. Since there is a Maypure branch near my home, I am seriously considering signing up for a package deal on their pigmentation treatment line and visiting regularly. Has anyone received pigmentation treatments at Maypure, such as toning or Meladus, for melasma, blemishes, or acne marks? I am curious how many sessions are typically required for the results to be satisfactory, and whether there are any specific skincare precautions I should take while undergoing the treatment, aside from applying sunscreen.
