numbuzin is a Korean skincare brand founded in 2018/2019 by Lee Il-joo and Kim Dae-young (under parent company Benow), built on the tagline "What's Your Number?" — a unique numbering system that assigns each product line a number tied to a specific skin concern (No.1 for soothing/barrier care, No.3 for glow and glass skin, No.5 for brightening/dark spots, No.9 for firming with NAD+ and 50 peptides, etc.), making skincare simple to shop without decoding ingredient lists. Each numbered line typically includes a toner, serum, and cream built around shared hero ingredients so they layer seamlessly. Best known for the viral No.3 Super Glowing Essence Toner, numbuzin turns complex K-beauty science into an intuitive, results-driven system — ideal for anyone wanting effective skincare with total clarity on what each product actually does.
