The COSRX Advanced Pure Vitamin C 23% Serum is a high-performance Korean skincare solution designed to revitalize tired, lackluster skin. With a concentrated 23% pure Vitamin C, this serum works synergistically with Vitamin E and Glutathione to deliver visible results: reduced fine lines, more even skin tone, and a luminous glow. This renewal formula is perfect for those seeking a potent yet gentle vitamin C serum that fits seamlessly into any skincare routine.

Product Overview

Vitamin C is a powerhouse antioxidant known for its ability to brighten skin, fade hyperpigmentation, and stimulate collagen production. The COSRX Advanced Pure Vitamin C 23% Serum harnesses this power at an effective 23% concentration, while adding Vitamin E to enhance absorption and stability, and Glutathione to further brighten and protect against environmental stressors. The result is a serum that not only improves skin texture and tone but also defends against premature aging.

Key Features and Benefits

• High Concentration Vitamin C (23%): Effectively targets dark spots, sun damage, and uneven pigmentation.
• Vitamin E Enriched: Boosts the efficacy of Vitamin C and provides additional antioxidant protection.
• Glutathione Infusion: A potent antioxidant that supports skin lightening and detoxification.
• Renewal Formula: Improved stability and absorption for maximum results.
• Fine Line Reduction: Stimulates collagen synthesis to smooth wrinkles and improve elasticity.
• Brightening Effect: Restores radiance to dull, tired skin for a healthy glow.

How to Use

For best results, apply a few drops to clean, dry skin after toner and before moisturizer. Use in your morning routine for antioxidant protection throughout the day. Start with every other day to build tolerance, then use daily. Always follow with sunscreen during daytime use, as Vitamin C can increase photosensitivity.

Who It Is For

This serum is ideal for anyone looking to address signs of aging, hyperpigmentation, or general dullness. Suitable for all skin types, including sensitive skin, though a patch test is recommended due to the high Vitamin C concentration. Perfect for those who want a powerful yet gentle brightening serum with proven ingredients.
