How many times is it usually recommended to use a melasma skin booster to see results?

Hello. The blemishes and melasma on my face have deepened, making my complexion look very dull. I looked into toning lasers, but I was worried that it might make my skin sensitive. However, I heard that there are excellent whitening products available these days that brighten the skin from deep within using injections or penetrating devices. So, I am planning to take this opportunity to get a consultation at a dermatology clinic and start treatment.

Generally, how many applications should I expect to use for this type of melasma skin booster?

I am looking to get a procedure because it simply won't fade with home care, considering the skin turnover cycle.

I am wondering if I will see visibly clearer skin if I use the melasma skin booster for the recommended duration. I would like to know the approximate recommended number of uses in advance before purchasing the package.

Please let me know if you have any tips or information on the recommended frequency for using skin boosters for melasma.
