Created in 2015 by biotech firm HUONS (known for injectable fillers), Skin1004 derives its name from the Korean angel number “1004” (pronounced “cheonsa”). The brand holds exclusive rights to Madagascar-sourced Centella Asiatica Stem Cell Culture Extract, shown in clinical trials to increase collagen production by 300% versus standard extracts. Their sterile ampoule packaging was adapted from hospital IV bags, making it a favorite for post-laser treatment in clinics like Seoul’s ID Hospital.
