Inquiry regarding differences in Pico Toning effects

Hello. I am writing to inquire as I am considering Pico Toning treatment to improve my facial blemishes and dull skin tone.

I have received Pico Toning before and heard that it is less irritating than traditional laser toning and effective for treating pigmentation; however, the effects of the Pico Toning I recently received have diminished, and I would like to receive a professional consultation to find out why.

Pico Toning Treatment Effects and Number of Sessions: Previously, my skin became clear after 10 sessions, but now I don't feel like there is much effect even after 8 sessions. In this case, I would like to know how many sessions I should receive.

Pico Toning Duration and Maintenance: I would like to inquire about the approximate duration of the clear skin condition following one set (usually 5–10 sessions) and whether there is a recommended maintenance treatment cycle. It has been about a year since I received the treatment.

Pico Toning Side Effects and Aftercare: Please advise on whether frequent treatments reduce effectiveness and if there are any aftercare precautions other than UV protection and moisturizing.

I would appreciate it if you could let me know the approximate cost of Pico Toning and available schedules for in-person consultations.
