COSRX Advanced The Vitamin C 23 Serum is formulated with a powerful antioxidant network featuring 23% pure Vitamin C, Super Vitamin E (Tocotrienol), and Glutathione. Based on research, this blend helps stabilise inherently unstable pure Vitamin C, allowing it to be delivered gently and effectively to the skin, making it more comfortable to use compared to many traditional Vitamin C serums.

Perfect for those already familiar with Vitamin C who want upgrade to a high potency formula for faster and more visible results.
It has a strange smell. Is this normal? This serum does not contain fragrances. However, the vitamin C, by nature, has a certain smell that does not affect the potency of the product.
With COSRX's advanced technology, it uses a specialised packaging that keeps vitamin C fresher: 1) Special Cap that controls gas released during vitamin C filling, 2) Special Container that prevents oxidation by blocking light, heat, and external air from entering, and 3) a Dropper that is indivually packaged for a more hygienic use.
