COSRX The Vitamin C 23 Serum | 23% Pure Vitamin C & Hyaluronic Acid

 

Section 1: About the Product

 

The COSRX Pure Vitamin C 23% Serum is a potent, proven serum for those seeking a special, intensive treatment. This highly concentrated formula is designed to deliver radiance, firmness, and hydration by targeting the most common signs of aging and sun damage, including dull complexions, fine lines, and stubborn hyperpigmentation.

This serum features 23% Pure Vitamin C (Ascorbic Acid), formulated at an optimal pH of 3.36 to maximize effectiveness while minimizing potential irritation. Unlike other serums, it contains an assortment of hydrating and replenishing ingredients like Hyaluronic Acid and Allantoin, making this high-strength formula one that can be well-tolerated by most skin types when introduced properly. It provides extraordinary results, leaving skin visibly brighter, smoother, and more hydrated.

Section 2: Key Benefits & Purpose

 

This serum is a multi-tasking powerhouse that provides a youthful-looking glow and diminishes signs of aging.

• Brightens Dull Complexions: The 23% Vitamin C actively works to brighten and revitalize dull, tired-looking skin, restoring a healthy, radiant glow.

• Fades Dark Spots & Hyperpigmentation: Effectively targets and reduces the appearance of dark spots, post-acne marks, and uneven skin tone for a clearer, more even complexion.

• Reduces Fine Lines & Wrinkles: As a potent antioxidant, it helps to fight free-radical damage and boost collagen, visibly improving and smoothing the appearance of fine lines and wrinkles.

• Firms & Smooths: Helps to improve skin elasticity, resulting in skin that feels firmer and has a smoother overall texture.

• Hydrates & Replenishes: While potent, this serum is also formulated with Hyaluronic Acid to lock in moisture and leave the skin feeling hydrated and smooth.

Section 3: Key Ingredients: The Science Inside

 

This serum’s power comes from its synergistic blend of high-performance ingredients.

Key Ingredient Breakdown:

• 23% Pure Vitamin C (Ascorbic Acid): The most potent form of Vitamin C. It actively fades dark spots, powerfully brightens the complexion, and stimulates collagen production to fight fine lines.

• Super Vitamin E (Tocotrienol): A highly potent form of Vitamin E that works synergistically with Vitamin C, boosting its antioxidant power and helping to fight signs of aging.

• Hyaluronic Acid (Sodium Hyaluronate): A powerful humectant that draws moisture into the skin, locking in hydration to keep the skin plump, smooth, and supple.

• Allantoin: A skin-soothing compound that helps to calm and protect the skin, mitigating potential irritation from the high-strength Vitamin C.

Section 4: How to Apply

 

Important: This is a highly concentrated product. A patch test on the body (like the inner arm) is recommended before using it on the face.

1. Step 1: After cleansing and toning, shake the bottle 1-2 times to lightly mix the formula.

2. Step 2: Apply 2-3 drops to your face. Gently massage in an outward motion, avoiding the eye area.

3. Step 3 (Daytime): This is a crucial step. For daytime use, you must follow up with a broad-spectrum SPF 30+ sunscreen to protect your skin, as Vitamin C can make it more sensitive to the sun.

4. Step 4 (For Stickiness): If you experience any stickiness, try applying a bit of your favorite moisturizer on top.

Essential Storage Tip: To prevent oxidation and maintain potency, store this serum in the fridge (3-10°C) as soon as you open it.
