Beauty of Joseon Glow Deep Serum Rice Alpha-Arbutin Niacinamide

A brightening serum with almost nothing in it that isn't working. Rice bran water replaces plain water as the base, 2% alpha-arbutin does the pigment work, and a nine-grain extract complex sits behind both. Alpha-arbutin at 2% — a tyrosinase inhibitor, so it works on the formation of pigment rather than lifting what is already there Rice bran water is the first ingredient, ahead of water, at roughly two-thirds of the formula Niacinamide, panthenol and glyceryl glucoside carry the hydration and tone side Nine grain and seed extracts close the list: Job's tears, soybean, barley, rice, sesame, wheat, mung bean, corn and Coptis japonica root No fragrance, no alcohol, no acids — this is a brightening serum you can layer under anything Evening use only, because alpha-arbutin degrades in light and heat
