How effective is a melasma skin booster?

I have been consistently getting Pico Toning to manage my pigmentation, and during my consultation, I was told that combining it with a melasma skin booster would create synergy. However, I honestly am not sure if the skin booster is actually effective for melasma.

I've seen that melasma skin boosters work by inhibiting melanin production, but I'm curious if their effectiveness improves when combined with laser treatments, or if they are meaningful on their own. It seems there are various types of melasma skin boosters, so I'm also unsure which ingredients I should focus on when choosing one.

I’d love to hear about the actual results from those who received a melasma skin booster along with their laser treatment!
