How many Pico Toning sessions are recommended?

I would like to inquire about the recommended number of Pico Toning sessions.

I'm looking into Pico Toning these days because of my freckles and blemishes. How many sessions do you usually need to see noticeable results?

Does the skin tone brighten after just one session, or do I need to do it consistently for melasma to fade?

I heard that the number of Pico Toning sessions varies depending on skin type and the degree of pigmentation; do people with sensitive skin require fewer sessions?

Is it common to schedule Pico Toning treatments every 1 to 2 weeks? I would also like to know how often treatments are recommended for maintenance. I am curious about the number of sessions where results were seen without pain or side effects, as well as the total cost range. Are there any discounts for multiple sessions?
