COSRX The Vitamin C 23 Serum 20ml
The Vitamin C 23 Serum is a high-potency, clinical-grade treatment designed to target the most stubborn signs of skin aging and environmental damage. Concentrated with 23% Pure Vitamin C, this serum acts as a powerful brightening agent that effectively fades acne scars and hyperpigmentation while restoring a youthful glow to dull complexions.
Its advanced formula is specifically engineered to remain stable and effective, delivering intensive antioxidant protection that firms the skin and visibly diminishes the appearance of fine lines and wrinkles.
Key Benefits
- High-Potency Brightening & Tone Correction Featuring a massive 23% concentration of Pure Vitamin C (Ascorbic Acid), this serum suppresses melanin production to diminish dark spots, blemishes, and uneven skin tone for a radiant, crystal-clear finish.
- Superior Antioxidant Defense Infused with Super Vitamin E (Tocotrienol), which boasts up to 50 times higher antioxidant activity than standard tocopherol. This duo works in synergy to neutralize free radicals and significantly boost collagen production.
- Skin-Plumping Hydration Utilizes Hyaluronic Acid to pull moisture deep into the skin tissue, ensuring that the high-strength Vitamin C works effectively without compromising the skin's essential moisture levels.
- Irritation Relief & Soothing Formulated with Allantoin, a powerful soothing agent that helps to mitigate the potential sensitivity often associated with high-percentage Vitamin C, making it more comfortable for daily use.
- Firming & Elasticity Support The combined action of Ascorbic Acid and Tocotrienol improves skin density, helping to firm sagging areas and smooth out the texture of fine lines.
Who It’s For
Perfect for all skin types struggling with hyperpigmentation, acne scarring, or dullness. It is an ideal choice for those looking for a professional-strength serum to address mature skin concerns and loss of elasticity.
How To Use
- Prep: After cleansing, during the serum phase, shake the bottle lightly 1 to 2 times from side to side.
- Apply: Apply a few drops to the skin and gently massage using your fingertips, moving from the inside of the face outwards until absorbed.
- Storage: Due to the high concentration of pure Vitamin C, store the bottle in the refrigerator to maintain freshness and prevent oxidation.
- Sun Protection: Always follow with a broad-spectrum SPF in the morning to protect the skin and the active ingredients from UV damage.
Pro Tip
Because this is a highly concentrated formula, if you are new to Vitamin C, start by using it every other night to allow your skin to adjust. To maximize the "glass skin" effect, apply this serum to slightly damp skin and follow immediately with a ceramide-rich moisturizer to seal in the brightening actives.
