Please tell me a cost-effective method for treating melasma.

Lately, I've started noticing one or two melasma spots on my face, so I'm looking into melasma treatments.

At first, I thought I could just cover it up with makeup, but it seems to be getting darker, so I'm thinking of getting a dermatological procedure.

However, after searching for melasma treatments, I found that there are more types of procedures than I expected and the price differences are significant, so I am having trouble deciding which method to choose. Since it is not a one-time treatment but often requires multiple sessions, the cost is also hard to ignore.

Since I prioritize cost-effectiveness, please recommend a melasma treatment that is not too expensive and offers promising results with consistent treatment. I would also appreciate it if you could let me know how many sessions are typically required, as well as the recommended frequency and treatment cycle.

Also, please let me know if the cost of melasma treatment varies significantly from clinic to clinic. Rather than choosing a clinic just because it is cheap, I want to receive a treatment that offers good value for the money. For those who have actually received melasma treatment, please share your reviews, including how many sessions you received in total and how much it cost.
