How satisfied are you with the melasma skin booster for improving surface and deep melasma?

I am worried because the freckles and blemishes on my face are getting uncontrollably dark.

I feel that simple laser toning alone will not be enough to treat deep melasma, so I am looking into injection treatments that are said to improve the skin's internal environment.

I see a lot of products containing whitening ingredients, so I am leaving this question to ask how satisfied people actually are with dark spot skin boosters.

I've heard that it creates a good synergy when combined with laser treatment, but since there is a cost involved, it is difficult to make a decision right away.

I would also like to know if those who have received the treatment are satisfied with the melasma skin booster, and if they also experience overall improvement in complexion or changes in skin texture.

Since the timing of onset and duration of effects vary from person to person, I would appreciate it if you could share your expert opinion on the necessary number of treatments or frequency to maximize satisfaction with the melasma skin booster.
