COSRX The Vitamin C 23 Serum

COSRX The Vitamin C 23 Serum delivers a potent 23% dose of pure ascorbic acid to brighten dullness, fade dark spots, and revitalize the complexion.

The formula is thoughtfully layered, combining a vitamin C-rich serum with an oil layer on top. This design helps preserve the stability of the active ingredient while offering a soft, moisturizing finish. Enhanced with super vitamin E (tocotrienols), hyaluronic acid, and allantoin, the serum supports elasticity, hydrates deeply, and soothes the skin as it works toward a more even, radiant tone.

To use, gently shake the bottle to blend both layers, then apply a few drops after cleansing, massaging from the centre outward. The lightweight texture absorbs smoothly, leaving skin supple

It’s effective both morning and evening, but when used during the day, don’t skip SPF 30 or higher
