The Beauty of Joseon Light On Serum Centella + Vita C is a lightweight brightening serum that solves the most common Vitamin C problem: irritation. By pairing a high-dose stable Vitamin C (3-O-Ethyl Ascorbic Acid at 10%) with a Centella Asiatica Extract base at 68%, the formula delivers meaningful brightening results while simultaneously calming the skin and preventing the sensitivity that 10% Vitamin C can trigger in many skin types.

The formula structure is straightforward but effective: 68% of the formula is Centella extract (not water), providing a continuous anti-inflammatory base that keeps the skin calm while the Vitamin C works. The 10% 3-O-Ethyl Ascorbic Acid is stable — it doesn't oxidise on contact with air the way pure L-Ascorbic Acid does — so the product maintains its effectiveness throughout its shelf life. Ascorbic Acid Polypeptide adds a complementary Vitamin C form.

Five additional botanicals broaden the formula's brightening and protective activity: Phellodendron Amurense (Amur cork tree), Kale (Brassica Oleracea Acephala), Satsuma Mandarin Peel (Citrus Unshiu), Kelp (Laminaria Japonica), and Eclipta Prostrata. Panthenol 1% repairs and soothes. Beta-Glucan and Fructooligosaccharides support the skin barrier and microbiome. Bisabolol adds additional calming. Hydrolyzed Hyaluronic Acid and Adenosine round out the serum with deep hydration and anti-ageing support. The Methyl Trimethicone base gives the serum its silky, light-as-water texture with no stickiness.
