COSRX The Vitamin C 23 Serum is an advanced brightening treatment formulated with a powerful 23% Pure Vitamin C (Ascorbic Acid) concentration to help improve dullness, uneven skin tone, and visible signs of aging. Designed for users already familiar with Vitamin C products, this high-strength serum helps restore radiance while supporting smoother, firmer, and healthier-looking skin. Its lightweight, non-sticky texture absorbs comfortably into the skin and delivers antioxidant care that helps protect against environmental stressors responsible for premature aging and loss of brightness.

The formula is further enhanced with Super Vitamin E (Tocotrienol) and Glutathione, creating an antioxidant-rich blend that helps improve overall skin clarity and luminosity. Whether you're dealing with post-breakout marks, dark spots, early fine lines, or a tired-looking complexion, this serum helps reveal brighter and more even-looking skin over time. The upgraded formula also eliminates the strong scent commonly associated with pure Vitamin C products while maintaining the original 23% Vitamin C concentration.

Powerful Antioxidant Care for Uneven Tone & Early Signs of Aging

Vitamin C is one of the most effective skincare ingredients for improving skin brightness and supporting collagen production, and COSRX The Vitamin C 23 Serum delivers it in a highly concentrated formula. Pure Vitamin C helps reduce the appearance of pigmentation and post-acne marks while promoting a naturally healthy glow.

Additional ingredients such as Niacinamide, Adenosine, Hyaluronic Acid, and Allantoin provide complementary benefits that help improve skin texture, support hydration, and enhance firmness. With regular use, the complexion appears more radiant, smoother, and revitalized.
