I have severe surface and deep melasma; is it possible to clear it up with Pico Toning alone?

Hello. I have quite severe surface melasma around my eyes and cheekbones that is easily visible to the naked eye, but after consulting with a doctor, I was told that there is also quite a lot of underlying melasma embedded deep within the skin.

I am seriously considering Pico Toning because I have received many recommendations from those around me saying it is effective and gentle on the skin. However, I am wondering if it is possible to achieve a clear finish with Pico Toning alone, even for someone like me with dark and deep pigmentation both on the surface and deep within. Or is it absolutely necessary to combine it with other treatments, such as lasers or skin boosters, to see results? If anyone has received Pico Toning with similar skin conditions, I would appreciate your valuable feedback or advice on the actual results and how many sessions it typically took for the pigmentation to start fading.
