Overview

COSRX The Vitamin C 23 Serum 20ml is the viral K-beauty brightening powerhouse: 23% pure vitamin C (ascorbic acid) in a stable, silky serum that visibly fades dark spots and post-acne marks, evens tone and restores glass-skin radiance. One of the highest pure vitamin C concentrations in skincare, delivering professional-level brightening at home.

Directions for Use

After cleansing and toning, apply a small amount (about half a dropper) to dry skin in the evening (or morning with sunscreen), focusing on dark spots. Start 2-3 times weekly and build as tolerated: 23% is strong. Follow with moisturiser; refrigerate after opening and use within the period stated, as pure vitamin C oxidises (discard if it turns dark brown).

High-strength vitamin C can tingle and cause initial redness. Patch test first and introduce slowly; not ideal for very sensitive or compromised skin. Avoid the eye area and broken skin. Do not layer with strong acids or retinol in the same routine while adjusting. Daily sunscreen is essential. Discontinue if persistent irritation develops.

Key ingredients: 23% pure vitamin C (ascorbic acid), vitamin E, allantoin. Full INCI list available on product packaging.
