Its lightweight yet potent formula penetrates deeply to deliver visible results while maintaining the skin’s natural moisture.

- Skin Type: Suitable for all skin types, particularly those with dull, uneven skin tone or sun damage.
Features:
- 23% Pure Vitamin C: One of the highest concentrations available, providing powerful antioxidant benefits and brightening effects.
- Fast Absorption: The lightweight formula absorbs quickly into the skin without leaving a sticky or greasy residue.
- Antioxidant-Rich: Protects the skin from environmental damage and free radicals that accelerate the signs of aging.
- Fades Hyperpigmentation: Gradually diminishes dark spots, acne scars, and sunspots for a more even complexion.
- Non-Irritating: Formulated with soothing ingredients to minimize irritation, even with the high concentration of vitamin C.
Key Ingredients & Benefits:
- 
23% Pure Vitamin C (Ascorbic Acid): - Brightens: Vitamin C is known for its powerful ability to reduce dullness and give the skin a radiant glow.
- Reduces Dark Spots: Fades hyperpigmentation, acne scars, and age spots, leading to a more even skin tone.
- Boosts Collagen Production: Stimulates collagen synthesis, improving skin firmness and reducing the appearance of fine lines and wrinkles.
- Protects from Free Radicals: Shields the skin from environmental stressors like pollution and UV damage, preventing premature aging.
 
- 
Super Vitamin E (Tocotrienol): - Antioxidant Support: Works synergistically with vitamin C to enhance its antioxidant effects and protect the skin from damage.
- Soothes and Moisturizes: Helps reduce irritation and keeps the skin hydrated, balancing the strong effects of vitamin C.
 
- 
Hyaluronic Acid: - Hydration: Keeps the skin deeply hydrated by attracting moisture to the skin's surface, maintaining suppleness and preventing dryness.
 
- 
Allantoin: - Soothing and Calming: Helps soothe irritated skin and supports skin regeneration, making it suitable for sensitive or reactive skin.
 
Benefits:
- Brightens Complexion: Vitamin C effectively evens out skin tone, reducing dark spots and giving the skin a healthy, radiant glow.
- Reduces Fine Lines and Wrinkles: By stimulating collagen production, this serum helps improve skin elasticity, reducing the appearance of fine lines and wrinkles.
- Fades Acne Scars: Lightens post-inflammatory hyperpigmentation from acne scars, promoting a clearer complexion.
- Prevents Aging: The powerful antioxidants protect the skin from environmental stressors like UV rays and pollution, which can cause premature aging.
- Hydrates and Nourishes: The added hyaluronic acid and tocotrienol help lock in moisture and protect the skin barrier, keeping the skin plump and soft.
How to Use:
- 
Step 1: Cleanse 
 Begin by thoroughly cleansing your face to remove dirt, oil, and impurities.
- 
Step 2: Apply the Serum - Use the dropper to dispense 2-3 drops of the serum into your palms.
- Gently apply the serum evenly across your face, avoiding the eye area.
- Lightly pat the serum into your skin until fully absorbed.
 
- 
Step 3: Follow with Moisturizer 
 After applying the serum, follow with a hydrating moisturizer to lock in moisture and soothe the skin.
- 
Step 4: Sunscreen (Daytime Use) 
 IMPORTANT: Vitamin C makes your skin more sensitive to sunlight, so always apply a broad-spectrum sunscreen during the day to protect your skin.
Frequency:
- Start Slowly: If you’re new to vitamin C, begin by using the serum every other day to allow your skin to adjust, then gradually increase to daily use.
- Day or Night: The serum can be used in your morning or evening routine, but always pair it with sunscreen in the daytime.
The COSRX The Vitamin C 23 Serum is a highly effective, concentrated solution for those looking to brighten their complexion, reduce dark spots, and protect their skin from the signs of aging. With consistent use, it reveals a more even, radiant, and youthful complexion.
