Freckle Laser Inquiry

Hello! I'm writing to inquire about freckle removal.

I had the Ruby Laser at Oval in January to remove my freckles, and about 30% of them remain. However, my skin condition deteriorated significantly after the Ruby Laser treatment, to the point where I still have some redness. (This is the first time I've experienced redness in my life.)

So, in the future, I would like to try a milder type of laser other than the ruby ​​laser. What is the relatively safest pigment laser that can remove freckles?
