This is an important and often overlooked question for patients traveling to Korea for dermatological care. Korea’s climate—marked by cold, dry winters and hot, humid summers—can significantly impact how the skin behaves and responds to treatment. For example, a regimen that works well in a dry or temperate climate might cause breakouts or sensitivity in Korea’s humid summer, or vice versa. International patients may also have different baseline skin conditions based on their home environment, and their skin may not be acclimated to Korean air quality or pollution levels. By asking this question, you’re encouraging the dermatologist to take a more customized and adaptive approach—perhaps adjusting active ingredients, suggesting barrier-repair treatments, or recommending specific timing for procedures like laser therapy based on the season. It also opens the door for a more holistic conversation about skincare products, sun protection, and aftercare that align with Korea’s unique environmental context.
