NUMBUZIN No.1 Pantothenic Active Up Soothing Serum 50ml
The numbuzin active up soothing serum is a 50ml bottle from the No.1 line, packed with pantothenic acid, panthenol and calming botanicals. Its milky, weightless texture floods reactive skin with hydration while quietly reducing the look of redness and post-cleanse tightness.
It slots easily into any routine as a soothing middle step between toner and cream, and works especially well after acids, retinol or long sun days. Skin feels immediately softer, more resilient and better prepared to face pollution, heat and other daily aggressors.
A go-to K-beauty serum for sensitive complexions and travelers dealing with dry planes and hotel air. A single-bottle way to test the No.1 barrier ritual before committing to the double pack.
