Which laser would be best for the deep acne pigmentation scars remaining on my chin?

A month ago, I forcefully squeezed a large, pustular pimple on my chin at home, leaving a very dark brown scar. I diligently applied regenerating cream, thinking it would fade over time, but even after a month, it remains a dark spot, making me upset every time I look in the mirror. Even when I try to cover it thickly with concealer, the scar stands out, and it feels like my makeup just looks thicker, so I am planning to seek help from a dermatologist using a laser. I searched online and found that Pico Toning or Excel V lasers are frequently recommended for this type of pigmentation, so I am debating which one would be more effective. Since it is not just a simple red mark but a pigmented scar that has already turned brown, I am worried that I will need to receive consistent treatments for quite a few sessions to remove it. If any Maypure members have successfully removed pigmented scars caused by improper pimple squeezing using a laser like mine, please share your advice. It would be a great help in choosing a clinic if you could leave an honest review regarding which equipment was used and how many sessions it took for the scar to start fading noticeably. Also, if you have any home care methods or tips to prevent scars from darkening again after pigment laser treatment, please share those as well.
