How much does the melasma skin booster treatment cost?

Hello.

I am a middle-aged woman who is upset because the dark spots on my face that appear whenever I go out cannot be covered up even with makeup. At first, I thought they would disappear on their own, but they seem to be getting darker over time, so I am considering getting a melasma skin booster treatment.

I've heard that it makes the skin clear from deep within, so I have high expectations. I called a few local clinics, but the prices for melasma skin boosters vary so much from place to place that I'm not sure what is a reasonable price. If I pay for a package of 3 or 5 sessions, what is a reasonable overall price range for melasma skin boosters?

I would like to go to a place with skilled professionals who provide thorough care, rather than a place that is too expensive. Please share some information if you have experience. I am also curious if marks remain on the face for a long time after the procedure.
