How satisfied are you with the melasma skin booster?

I have fair skin, but I am highly sensitive to melanin, so blemishes appear even with just a little sun exposure. When I was younger, I used to get tiny, dotted freckles, but lately, I've been seeing melasma that seems to spread out a bit.

I have been consistently receiving toning treatments, but I am considering Maypure because they uniquely offer a melasma skin booster. I am hesitant because there aren't many reviews when searching on sites like Naver. For those who have tried it, how satisfied were you compared to laser treatments? The price seems to be equivalent to about 5 toning sessions; is the melasma skin booster effective for the cost? I would like to hear honest reviews on whether you can definitely feel your melasma fading after just one session.
