Round lab

Inspired by Korea’s natural landscapes and crafted for sensitive skin, Round Lab blends gentle ingredients with clinical care. Best known for their Dokdo line, made with deep sea water from Ulleungdo Island, each product is designed to hydrate, calm, and restore the skin’s natural barrier.

Clean, minimalist, and deeply effective—Round Lab is a brand that reflects the softness of nature with the strength of science.

Curated with intention, the Round Lab collection at Tokki Ku brings the freshness of Korea’s coastlines straight to your skincare ritual.
