COSRX Advanced The Vitamin C 23 Serum, 20ml

Product Description

COSRX Advanced The Vitamin C 23 Serum is a high-potency, dermatologist-level treatment designed to dramatically revitalize dull, tired, and aging skin. Formulated with a massive 23% concentration of Pure Vitamin C (Ascorbic Acid), this serum acts as a powerful brightening agent that targets stubborn acne scars, sun spots, and uneven hyperpigmentation.

The formula is uniquely stabilized with a rich antioxidant blend of Vitamin E (Tocotrienols and Tocopherol), which works in synergy to amplify the effects of Vitamin C while protecting the skin from environmental oxidative stress. To ensure the high concentration of actives remains comfortable on the skin, it is infused with Sodium Hyaluronate for deep hydration and Allantoin to soothe potential irritation. The result is a high-performance "glow serum" that not only brightens but also significantly improves skin texture and diminishes the appearance of fine lines.

Key Benefits

Maximum Brightening Power: The 23% pure Vitamin C concentration effectively fades post-inflammatory hyperpigmentation (acne scars) and dark spots.

Antioxidant Synergy: Infused with Glutathione and a Vitamin E complex (Tocotrienols) to shield the skin from free radicals and prevent premature aging.

Moisture Retention: Contains Sodium Hyaluronate and Squalane to keep the skin plump and hydrated, counteracting the potential drying effect of high-strength Vitamin C.

Anti-Aging Support: Features Adenosine and Niacinamide to refine skin texture and minimize the appearance of fine lines and wrinkles.

Soothing Formula: Includes Allantoin and Licorice Root extract to calm the skin and reduce redness during the brightening process.

How To Use

After cleansing, during the serum step, shake the bottle lightly 1–2 times from side to side.

Apply a few drops to the skin and gently massage with your fingertips, starting from the center of the face and working outwards.

Pro Tip: Because of the high concentration of Pure Vitamin C, it is highly recommended to store this product in the refrigerator after opening to prevent oxidation and maintain potency.

Sun Protection: Always apply a broad-spectrum sunscreen (SPF 30 or higher) as the final step in your morning routine when using this serum.
