Who should I recommend the melasma skin booster for, and how often?

I'm really worried about my melasma, so I'm looking into melasma skin boosters!

I've always had some blemishes, but lately they seem to have gotten much darker. I'm very diligent with sunscreen, so I don't know why this is happening. I've heard that melasma skin boosters are effective, but I'm not sure if my case is even suitable for it. I'm curious about what kind of skin concerns this treatment is best suited for, and whether the effectiveness varies depending on the type of melasma. I've also heard that it's less irritating than laser treatment, so I'd like to ask if it's safe for sensitive skin.

I really have no idea about the treatment cycle for melasma skin boosters. I want to know how often I need to get them, and if the initial treatment involves intensive therapy. I also want to know if I need to receive them consistently to maintain the results, or if I can extend the intervals once my skin improves to a certain extent. I’d also like to know when the effects start to show.

Please, those of you who have received the melasma skin booster, let me know! I want to know if I am a recommended candidate and what the usage frequency is!! Also, I would be really grateful if you could let me know the price range as well.
