COSRX The Vitamin C 13 Serum, 20ml

Product Description

COSRX The Vitamin C 13 Serum is a high-performance, daily-use brightening treatment designed to effectively fade hyperpigmentation and restore a natural glow to dull skin. Formulated with a stabilized 13% concentration of Pure Vitamin C (Ascorbic Acid), this serum is the perfect "Goldilocks" choice—potent enough to deliver visible results on dark spots and blemishes, yet gentle enough for those who may find higher concentrations too intense.

The formula is amplified by a "Super Vitamin E" complex (Tocotrienols), which provides up to 50 times the antioxidant power of standard Vitamin E, working in harmony with Vitamin C to shield the skin from environmental damage. To ensure a comfortable and hydrated finish, the serum is enriched with Hyaluronic Acid, Allantoin, and Panthenol, which soothe the skin barrier and prevent the dryness often associated with active treatments. With the added benefits of Niacinamide and Licorice Root Extract, it targets uneven skin tone from multiple angles for a clearer, more refined complexion.

Key Benefits

Effective Dark Spot Correction: The 13% pure Vitamin C concentration targets melanin production to fade acne scars, sun spots, and pigmentation.

Daily Antioxidant Shield: Features Glutathione and Super Vitamin E to neutralize free radicals and prevent premature skin aging.

Anti-Aging & Texture Refinement: Contains Adenosine and Caffeine to improve the appearance of fine lines and reduce morning puffiness.

Soothing Hydration: Infused with Squalane, Hyaluronic Acid, and Panthenol to maintain the skin’s oil-water balance and minimize irritation.

Lightweight Texture: The fast-absorbing, non-sticky formula is suitable for all skin types, including those with oily or combination skin.

How To Use

After cleansing and toning, apply a moderate amount (2–3 drops) to the face.

Gently massage with your fingertips in outward circular motions to aid absorption.

Pro Tip: To maintain maximum potency and prevent oxidation, store the bottle in the refrigerator and keep it away from direct sunlight.

Sun Protection: Always apply a broad-spectrum sunscreen as the final step in your morning routine, as Vitamin C can increase the skin's sensitivity to the sun.
