The Cosrx Vitamin C 23 Serum is a potent 23% L-Ascorbic serum that provides high performance brightening and prevents early signs of ageing. It is rich in antioxidants and nourishes the skin to add a radiant glow. It has a non-greasy formula that absorbs quickly, and is higly moisturising with Sodium Hyaluronate to minimise irritation or dryness.

The serum helps improve skin elasticity, reduce dark spots, fine lines and appearance of pores.

The high concentration of L-Ascorbic Acid (a potent form of Vitamin C) fades acne scars and brightens and evens out skin tone, by reducing pigmentation caused by UV exposure. It also uses a more powerful form of Vitamin E, Tocotreniol or super Vitamin E. This can provide upto 50 times more antioxidant benefits than only Tocopherol, which helps slow early signs of aging.

The hypoallergenic formula is best for intermediate users, and for those who have previously used concentrated active ingredients. It can be used during the day as well, as Vitamin C and E work with your sunscreen during to protect the skin from UV damage.
