How effective is the Pico Toning laser for freckles and blemishes?

It was an exceptionally hot summer... perhaps because I received a lot of UV rays

The freckles and dark spots on both cheeks and around my eyes have become noticeably darker.

Even if I try to cover it with concealer, it doesn't cover well.

My overall face tone has become dull, so I look dark.

As a result, the Pico Toning Laser

I'm interested after seeing reviews saying it's effective for pigmentation treatment.

Even if your skin has a mix of light blemishes and deep melasma, like mine

I am wondering if I can see a clearer complexion effect with the Pico Toning laser.

I’ve heard that it is usually difficult to see results from a single toning laser session and that periodic treatments are necessary. I would like to know the minimum number of sessions you recommend to see noticeable improvement!
