COSRX The Vitamin C 23 Serum 20ml
COSRX The Vitamin C 23 Serum is a high-potency Korean facial serum formulated with 23% pure vitamin C to target dullness, uneven-looking skin tone, dark spots and visible signs of aging. Designed for experienced vitamin C users seeking intensive brightening care, this concentrated K-Beauty treatment combines powerful antioxidants with hydrating and skin-conditioning ingredients for a smoother, firmer and more radiant-looking complexion.
At the heart of the formula is 23% pure ascorbic acid, complemented by 3-O-ethyl ascorbic acid for an advanced vitamin C-focused skincare approach. Glutathione, tocopherol and tocotrienols provide additional antioxidant support, while niacinamide helps improve the appearance of uneven tone and promotes a brighter-looking complexion.
Panthenol, sodium hyaluronate, squalane and allantoin help maintain hydration and skin comfort, balancing the intensive antioxidant formula. Adenosine complements its anti-aging profile, making the serum particularly suitable for routines targeting fine lines, loss of elasticity, rough texture and a tired-looking complexion.
The concentrated formula is an excellent choice for experienced skincare users looking to upgrade from lower-strength vitamin C products. Apply a small amount after cleansing and toning, followed by moisturizer. When used during the daytime, finish the routine with broad-spectrum SPF protection.
Ideal for customers searching for COSRX vitamin C serum, 23% vitamin C serum, Korean brightening serum, dark spot skincare, antioxidant face serum or high-strength K-Beauty vitamin C, COSRX The Vitamin C 23 Serum delivers intensive brightening and radiance care in a concentrated daily treatment.
