Origin: South Korea
Known for: Birch juice, Dokdo toner, ultra-gentle hydration
The Story Behind Round Lab
Round Lab was founded with a mission to create 'round,' well-rounded skincare — products that are balanced, gentle, and effective for even the most reactive skin. The brand sources mineral-rich deep sea water from Ulleungdo and Dokdo islands off Korea's east coast, which gives their Dokdo line its signature soothing properties. Their Birch Juice Moisturizing line, featuring birch sap harvested in spring, became a cult favorite for delivering intense hydration in a weightless, watery texture that never feels sticky. Round Lab has quietly become one of the most recommended brands in Korean dermatology clinics for patients with compromised skin barriers who need hydration without any risk of irritation.

Is Round Lab Dokdo Toner good for sensitive skin? ▾
Yes — the Dokdo Toner uses deep sea water rich in minerals to soothe and hydrate without any irritating additives. It's one of the most frequently recommended toners in Korean dermatology clinics for sensitive and reactive skin.
What does Round Lab deep sea water do? ▾
The deep sea water from Ulleungdo contains over 70 minerals (magnesium, calcium, potassium) that help strengthen the skin barrier, reduce inflammation, and improve moisture retention.
