Centella Asiatica (cica) shows up in nearly every calming K-beauty product, including as a listed antioxidant in Anua's toner alongside its heartleaf base — it's the ingredient most brands reach for when they want to say 'calms redness' without hedging.
Rice is Beauty of Joseon's whole identity, and it's rooted in real history: in the Joseon Dynasty, rice bran water was used the way we use toner today, called Beauty Water. That same logic shows up in the brand's Relief Sun formula, which contains rice extract at 30% alongside a grain probiotics complex meant to help nourish skin's natural strength.
Niacinamide is the quiet workhorse — it's in Beauty of Joseon's Ginseng Essence Water at 2%, and it turns up again in the brand's Relief Sun SPF, generally credited with supporting the skin barrier, evening tone, and minimizing the look of pores.
Propolis gets grouped with ingredients that soothe inflammation and support healing, and it's the backbone of 'glow serum' style products from both COSRX and Beauty of Joseon.
Ginseng, at 80% concentration in Beauty of Joseon's essence, is a genuine hanbang (traditional Korean medicine) ingredient credited with improving circulation, supporting collagen production, and brightening — the brand even points to Hwang Jin-yi, one of the most celebrated kisaengs of the Joseon dynasty, who reportedly bathed in ginseng root water.
