Data analysis | Statistical period: 2025 · Institution announcement: April 24, 2026 · Source checked: September 22, 2026
The number of overseas patients visiting Korean dermatology clinics and the popularity of individual procedures are not represented by the same statistic. In an announcement released on April 24, 2026, the Ministry of Health and Welfare stated that the number of foreign patients who visited Korea in 2025 reached 2.01 million. By medical department, dermatology accounted for 1.313 million patients, or 62.9%. This figure shows the scale of dermatology care within the attraction of foreign patients, but it does not indicate which procedures were chosen most often.[1]
Dermatology’s share is not the market share of individual procedures
Statistics by medical department and statistics by procedure address different questions. The former examine which department provided the care. To compare choices among skin boosters, Botox, lasers, and lifting procedures, separate data distinguishing individual procedures is required. Concluding from dermatology’s high share alone that a particular procedure or product is the most popular among foreign patients goes beyond the scope of the information provided by this data.
Accordingly, when attaching the name of a specific procedure to these statistics, the evidentiary link must be checked. If department-level statistics are presented and a particular product is then described as the procedure chosen most often, the procedure-level figures needed to support that connection are missing. Search volume, consultation inquiries, booking numbers, and the number of procedures actually performed are also different indicators, so it is more accurate not to combine them into a single popularity ranking.
Why 2.01 million and 62.9% should not be multiplied directly
The total number of visiting patients in the press release and the share by medical department should not be assumed to have the same denominator. The number of dermatology patients should be cited as the 1.313 million given in the source, and one should avoid creating a new figure by multiplying 2.01 million by 62.9%. Before comparing or adding figures from different tables, first check the population covered by each table, the units, and the rules for handling duplicate counts.[1]
Accurate analysis is not about producing more large numbers; it is about clarifying the questions the numbers can answer. If one table shows visitor volume by country and another shows the composition by medical department, placing the two tables side by side does not, by itself, prove a particular nationality’s preference for a particular procedure.
Although the data was announced in 2026, the performance period is 2025
The data was announced on April 24, 2026, but its statistical period is 2025. Even if this analysis is read in September 2026, the figures cannot be rephrased as 2026 performance or cumulative visitors to date. Clearly indicating the article date, the institution’s announcement date, and the statistical reference year prevents readers from confusing the timing of the data.[1]
It is also necessary to check whether new annual statistics or revised figures have been published. However, if no new figures have been confirmed, the existing data should not be presented as a breaking update; it can instead be handled as an analytical article that specifies the period it covers. Stating the date on which the source was checked and saying that the statistics themselves were updated on that date are separate matters.
What else is needed to discuss popular procedures by country?
Data distinguishing both nationality and individual procedure, as well as the survey period, survey population, and scope of the sample, is required. If the data consists of booking records from a single medical institution, it should be described as the result for that institution and period, not generalized as a preference across Korea. Survey responses must be distinguished from actual procedures performed, and it should also be stated whether multiple selections were allowed. Without this information, it is appropriate to leave rankings of popular procedures by country unconfirmed.
DERME VERDICT
The fact that dermatology accounts for a high share of foreign-patient statistics for 2025 must be distinguished from the claim that a particular procedure is the most popular. When using this data, first explain the structure of medical departments in Korean medical tourism; to discuss individual procedures or preferences by country, present additional data suited to those claims. The key is not to reinterpret statistics showing visitor volume as evidence of a procedure ranking or of a treatment’s suitability for an individual.
