Jayjun

Jayjun Cosmetic is a South Korean brand founded in 2015 in Seongnam, Gyeonggi-Do province, by a group of plastic surgeons, dermatologists, and researchers united by a single goal: to develop skincare solutions inspired by a clinical approach. The brand's guiding principle — encapsulated in the slogan "Responsible for Beauty" — expresses a clear commitment: every formula is designed using raw materials selected by the in-house research and development teams, with particular attention to skin tolerance. All products are designed, tested, and manufactured in Korea, and the brand is now distributed in over thirty countries across Asia, Europe, and North America.
