The short answer
Is one session on a trip enough for melasma?
Usually not. The American Academy of Dermatology notes that melasma treatments take time to work, and the British Association of Dermatologists says there is no cure at present, that melasma often returns after treatments stop, and that laser results vary. So treat a single appointment on a trip as the start of a plan: ask how many sessions the doctor expects, how far apart they are, what you do at home between them, and who continues once you leave Korea. Whether your own dark patches are melasma is for the doctor who examines you to say.

Why melasma is treated over time.
The American Academy of Dermatology notes that it takes time for melasma treatments to work and that melasma can persist for years. The British Association of Dermatologists says there is no cure for melasma at present, that treatments may improve its appearance, and that it often returns after treatments stop.
Not every dark patch is melasma, and the guidance above is written about melasma only. The doctor who examines your skin is the one who says what you have and what the plan should be; ask them which condition they are treating and what their plan is built around.
American Academy of DermatologyAmerican Academy of DermatologyBritish Association of DermatologistsWhat the guidance says about laser for melasma.
The British Association of Dermatologists notes that laser results for melasma are variable, and that laser can worsen pigmentation or leave patches of lighter skin, more often in people of colour. Ask the doctor how they weigh that for your skin and how it shapes the number and spacing of sessions, even when you only have a few days in Korea.
If a plan promises to clear pigment in one visit, ask how the doctor expects the result to hold and what happens if pigment returns.
British Association of DermatologistsWhat the guidance says about the time between sessions.
For melasma, the American Academy of Dermatology advises protecting your skin every day, even on cloudy days and after swimming or sweating, reapplying sunscreen every two hours, and for melasma using a tinted sunscreen containing iron oxide with SPF 30 or higher. It also notes that visible light can worsen melasma, especially in darker skin tones, and that a product that burns or stings can make dark spots darker. The British Association of Dermatologists suggests shade between 11 am and 3 pm on sunny days.
Ask the doctor which products to use and which to stop, and write the names down. A holiday with long days outdoors is exactly when this matters most.

Decide early where the later sessions happen: on a return trip to Korea, or with a doctor at home. Either can work, but the doctor who continues needs to know what was done. Ask for the treatment names, device names and dates in writing, and request copies of your records in English, as the CDC Yellow Book advises for travellers.
UK NHS guidance suggests understanding all costs, including aftercare and anything needed to maintain the result. For pigment plans that means the full course and the upkeep afterwards, not only the first session.

What travelers ask
The questions behind the search.
Yes, for some concerns. The British Association of Dermatologists says melasma often returns after treatments stop, which is why sun protection and upkeep are part of most plans.
Official guidanceIt can. The British Association of Dermatologists notes that laser can worsen pigmentation or leave lighter patches, more often in people of colour. Ask the doctor how they reduce that risk for your skin.
Official guidanceIt may be enough to start. The American Academy of Dermatology notes that melasma treatments take time to work, so plan how the later steps will happen before you book.
