I feel like laser treatment alone has its limits, so I'm wondering how to efficiently determine the recommended number of melasma skin boosters relative to their effectiveness.

My melasma is getting darker, so I am considering a melasma skin booster along with laser treatment. My current concerns are as follows: Melasma area: Mainly on both cheeks and cheekbones; generally light but covering a large area. Skin type: Combination, with dryness and sensitivity fluctuating by season. As a working professional, I can only tolerate a maximum of 2 to 3 days of downtime. Therefore, I am wondering how reasonable the cost is relative to the effectiveness of the melasma skin booster, and whether it offers good value for money compared to laser treatment alone.

I understand that the composition of melasma skin boosters varies depending on the type—ranging from ingredients that inhibit melanin production to those focused on whitening and antioxidants—and that the cost per session also differs by clinic, starting from around tens of thousands of won. My goal is to use melasma skin boosters in conjunction with laser treatment to reduce the recurrence of melasma and to make my overall facial tone clearer. Based on these conditions, could you please advise on the minimum number of sessions and the optimal frequency for efficiency, the cost range for single sessions and packages, and any precautions I should take when combining laser treatment with melasma skin boosters?
