Which of the various freckle removal lasers is effective?

These days, my freckles are getting darker and my skin tone is getting duller, so I'm inquiring about freckle removal laser.

Looking at the internet, there are so many different types of freckle removal lasers that I'm confused about which one is more effective, such as pico laser, toning laser, or IPL.

For someone like me who has deep freckles and blemishes, which laser treatment would be best for freckle removal?

Please also provide information on the treatment cycle, recovery period, and side effects.
