YOSAE 요새
From the Korean word meaning "fortress" - A name that reflects our belief that skincare should respect the skin barrier while meeting the pace of real life.
LAB
Our disciplined, biotech-forward approach to formulation: purposeful ingredients, clear active concentrations, and communication grounded in evidence.
Two founders. One shared obsession with the skin barrier.
Science with sincerity
We anchor the care behind every decision in the Korean concept of "jeongseong": sincere, wholehearted effort. For YOSAElab, that means developing with precision, communicating with clarity, and creating rituals that feel calm rather than complicated.
