Is laser treatment for melasma removal at a dermatology clinic effective?

I am worried that the increase in melasma as I get older is inevitable. I try to block it with sunscreen when the sunlight is strong, but I am concerned because it is ineffective these days when the UV rays are so intense.

Are the melasma removal procedures performed at dermatology clinics actually effective? I’ve heard that such treatments are ineffective. I’ve also heard that if done incorrectly, the melasma can become darker or even flare up, so I’m curious to know for sure. How many sessions would be needed to see results, and what is the recommended interval between treatments?
