COSRX The Vitamin C 23 Serumsuper Vitamin E+ Hyaluronic

• 23% Pure Vitamin C (Ascorbic Acid): A concentrated dose that effectively targets hyperpigmentation, dark spots, and uneven skin tone.
• Super Vitamin E (Tocotrienol): Boasts up to 50 times the antioxidant power of regular Vitamin E, working in perfect synergy with Vitamin C to boost skin elasticity.
• Hyaluronic Acid: Ensures your skin stays hydrated and plump, minimizing the potential for the "tingling" sensation often associated with high-strength Vitamin C.
• Allantoin: Added to soothe and protect the skin, reducing irritation for a more comfortable application.
• Anti-Aging Power: Not only brightens but also stimulates collagen production to help reduce the appearance of fine lines and wrinkles.

Vitamin C is an "active" ingredient; follow these steps for the best results:

1. Shake Gently: Give the bottle a slight side-to-side shake before use to mix the formula (do not shake vigorously).
2. Apply: After cleansing and toning, apply 2-3 drops to each cheek and forehead.
3. Massage: Gently massage the serum into the skin using circular motions, following the skin's texture.
4. Seal & Protect: Follow with a moisturizer. If using in the morning, SPF 30+ is mandatory, as Vitamin C can make skin more sensitive to the sun.
5. Storage: Keep this bottle in the refrigerator to prevent oxidation and maintain its potency. Use within 2 months of opening.
