JAYJUN

JAYJUN began in 2015 when a group of South Korean plastic surgeons, dermatologists and researchers set out to package professional-grade skincare into formats ordinary consumers could use at home. Their first breakout was the Real Water Brightening Black Mask, a three-step sheet-mask system that bundled a cleansing, treating and moisturizing step into a single sachet, alongside the Vita Snow Essence. Sheet masks remain the brand's signature, and that focus shows in the sample range, which leans heavily on hydrating and brightening masks plus eye patches built around hyaluronic acid, collagen and green tea. From its Korean base, JAYJUN expanded into more than 30 countries, building distribution across China, Hong Kong, Vietnam and beyond, and is now a fixture on K-beauty marketplaces like StyleKorean and Stylevana. The brand markets itself on a dermatologist-and-surgeon origin story, and while its formulas use well-established hydrating actives, its efficacy claims rest largely on brand-led development rather than extensive independent clinical validation. As a roughly decade-old company it has a solid commercial track record in the sheet-mask category without the deep research pedigree of legacy derm brands.
