Dark spot skin booster satisfaction question

How satisfied are you with the melasma skin booster?
I am an office worker who has been stressed for a long time due to melasma and blemishes. I have consistently received laser toning treatments, but there is a limit to how much they can fade. Recently, I have been considering a skin booster procedure that directly injects whitening ingredients into the dermis. Since the cost is quite high, I am very curious about the actual satisfaction levels of patients with melasma skin boosters. No matter how good a procedure is, I hesitate to pay for it if the perceived effect is low.

I am confused because, based on what I hear from others, some are highly satisfied with the melasma skin booster overall, citing improved complexion and relief from internal dryness, while others say their satisfaction falls short of expectations since it is difficult to completely erase the melasma itself. I would like to know how satisfied you are with this product on a scale of 1 to 10. It would be a great help in making my decision if you could share your honest reviews on whether you definitely saw improvements in melasma and tone-up effects commensurate with the money you spent.
