Which months are best for a skin treatment in Korea?
The month matters less than what you plan to do outdoors in the weeks around treatment.

The short answer
Which months are best for a skin treatment in Korea?
No single month is best, and the month is not what decides it. For many light and laser treatments the deciding factor is sun on both sides of the date: the American Academy of Dermatology's laser scar guidance says a dermatologist cannot treat you if you arrive with a tan or sunburn, and DermNet advises avoiding sun in the days and weeks before and after intense pulsed light. The Korea Tourism Organization describes summer, June to August, as sweltering, with a rainy season roughly from the end of June to the end of July, autumn averaging around 15 degrees Celsius and winter around 0 to 1 degree. So pick the month you can travel in, then ask the clinician how many low-sun days they want before and after your treatment, and build the itinerary around those two numbers.

Why sun sets the timing.
The American Academy of Dermatology's advice on laser scar treatment says that if you arrive with a tan or sunburn, the dermatologist cannot treat you. DermNet advises avoiding sun exposure in the days and weeks before and after intense pulsed light. After acne scar treatment, the Academy advises limiting daytime time outdoors for six to eight weeks.
For pigment concerns, DermNet notes that pigmentation may reappear on exposure to summer sun even after a good response. So the useful question is not only which month, but how much time in strong sun your trip and your life at home will involve in the weeks that follow.

The Korea Tourism Organization describes the seasons this way. Spring runs from March to May, with chilly days often lasting until mid-March. Summer, June to August, is sweltering, and the rainy season falls roughly from the end of June to the end of July; typhoons can come between June and October. Autumn, September to November, averages around 15 degrees Celsius. In winter the average drops to about 0 to 1 degree Celsius.
Summer heat also means more sweating. The Academy advises reapplying sunscreen every two hours and immediately after sweating, and notes that sun protection matters on cloudy days and in winter too.

Outdoor-heavy days are not automatically safe just because they come first. DermNet advises avoiding sun in the days and weeks before intense pulsed light as well as after it, and the Academy says a tan or sunburn means the dermatologist cannot treat you at all. Ask the clinician how many low-sun days they want on each side of your treatment, then place hiking, beaches and long walking tours outside that window in both directions. For the days after, indoor sights, shaded routes and shorter outdoor stretches are the easy substitutes.
If you are considering a treatment course with several sessions, think about the months at home as well. A trip in a cooler month can still be followed by a sunny season where you live.
