Our Story

We didn’t start as a beauty brand. We started as a lab.

Youlief is the skincare line of Plcoskin, a Korean regenerative-medicine company that engineers artificial soft tissue for reconstructive surgery. A company that studies how skin rebuilds itself learns what skin actually needs — and what it doesn’t.

Since 2018, that knowledge has become Korea’s idea of an easy first derma step: gentle, low-irritation formulas proven on the country’s toughest beauty shelves.
