Is the freckle laser effective?

My freckles seem to be getting darker, so I'm considering freckle laser treatment, but I'm wondering if it's actually effective. These days, people draw freckles on and accept them as part of their charm. I'm sure people with freckles on their face will agree, but I really want to get rid of them completely. Foundation and concealer with good coverage are good, but since I don't have them in the first place, this seems like the best option.

I'd like to know if freckles will noticeably fade after just one laser treatment, or if I'll need multiple treatments. I'd also like to know how long scabs and redness typically last after the treatment, and if it causes any inconvenience in daily life. I'm also curious to hear from people who have actually undergone the procedure. I'd also like to know if the risk of recurrence is high. If anyone has had freckle laser treatment, I'd appreciate any reviews or advice.
