About NUMBUZIN
numbuzin is a Korean skincare brand built around a simple idea: skincare should be easier to understand. According to the brand, complex names and endless routines leave people wondering whether a product is right for their skin, so numbuzin puts its solutions into numbers.
Instead of starting from skin types or long ingredient lists, the brand asks one question: what is your main skin concern right now?
How the numbers work
According to numbuzin, one number equals one clear skin solution. Each number stands for a specific skin goal, so you can find a product that fits what your skin needs without decoding complicated names. The brand also says it does not chase trends.
On the brand’s official site, the numbers include No.0, No.1, No.3, No.5 and No.9. Kool Seoul carries No.1 to No.5 products.
No.1 and No.2
No.1 Pantothenic is the line for hydration and soothing, with the Pantothenic Active Up Soothing Serum, the Pantothenic Active Soothing Cream, a Watery Sun Cream and the Hyaluronic Pantothenic Clear Soothing Gauze Pack. No.1 also includes the Calming Fresh Clear Toner and the Clean Sweep Cleansing Oil.
No.2 is the Rose PDRN Collagen line: the Plumping Serum, the 2X Plumping Serum and the Plumping Mask Pack.
No.3 and No.4
No.3 Boodleboodle focuses on pores and skin texture: First Grain Boosting Toner, Pore Zero Well-Absorbed Pads, Pore Grain Cleansing Oil and a Skin Texture Serum Pack. The No.3 Blue Bio Retinol Pore Remodeling Ampoule belongs to the same number.
No.4 is represented by the Serapil Peeled Egg Serum. For cleansing, we also carry the No.2 Deep Clean Fresh Cream Cleansing Foam.
No.5 Glutathione C
