    Step by step instruction: COSRX Advanced The Vitamin C 23 Serum 20ml

    • How to use COSRX Advanced The Vitamin C 23 Serum 20ml

      1. Perform a Patch Test (Crucial for First-Time Users): Before your first full application, apply 1-2 drops to a small, discreet area of skin, such as behind your ear or on your inner arm. Due to its high concentration, it's essential to ensure your skin tolerates the serum without irritation. Wait 24 hours.
      2. Activate the Formula: The serum has a bi-layer formula to maintain freshness. Before each use, with the dropper cap securely tightened, lightly shake the bottle once or twice to mix the oil and water layers.
      3. Start with Cleansed, Toned Skin: Apply the serum after your cleansing and toning steps. Ensure your face is dry to allow for optimal absorption.
      4. Dispense and Apply: Unscrew the dropper and dispense 2-3 drops onto your fingertips or the palm of your hand. Gently apply to your face, starting from the cheeks and moving outwards. Pat the serum into the skin, focusing on areas of concern like dark spots or uneven texture. Avoid the delicate eye and mouth areas.
      5. Allow for Absorption: Let the serum absorb into your skin for a minute or two before proceeding to the next step. It is normal to feel a mild tingling sensation as your skin acclimates to the high concentration of Vitamin C.
      6. Follow with Moisturizer: Once the serum has absorbed, apply a gentle, hydrating moisturizer. This helps to soothe the skin and lock in the serum's benefits.
      7. Essential Morning Step - Sunscreen: If using in your morning routine, you MUST finish with a broad-spectrum sunscreen of SPF 30 or higher. High-strength Vitamin C can increase photosensitivity. Sunscreen protects your skin and prevents the formation of new hyperpigmentation.
      8. Proper Storage is Key: To protect the potency of the Vitamin C, screw the cap on tightly immediately after use and store the bottle upright in the refrigerator.

    Routine integration with COSRX Advanced The Vitamin C 23 Serum 20ml

    • Integrating COSRX Advanced The Vitamin C 23 Serum 20ml into Your Skincare Flow

      • As an Active Treatment Serum: This is a powerful serum that should be integrated into your routine after cleansing and toning, but before applying your moisturizer.
      • Start Slowly: If you are new to high-strength Vitamin C, begin by using the serum just 2-3 times per week. You can gradually increase the frequency to daily use (morning or night) as your skin builds tolerance.
      • Best for Experienced Users: This 23% concentration is best suited for those who have previously used and tolerated Vitamin C serums with lower concentrations.
      • AM or PM Use: This serum can be used in the morning to provide powerful antioxidant protection against environmental damage, or at night to work on skin repair. If using in the AM, sunscreen is non-negotiable.
      • Avoid Other High-Strength Actives: Do not use this serum in the same routine as other high-concentration exfoliants like AHA, BHA, or Retinol to avoid over-exfoliating and irritating the skin. Use them on alternate days or at different times of the day.

Its popularity is a testament to its visible, clinically-proven results.

    Scent, texture and feel of COSRX Advanced The Vitamin C 23 Serum 20ml

    • Scent: This serum has a distinct, metallic, or savoury scent, often described by users as being like "hot dogs." This is completely normal and is the natural smell of highly concentrated, pure L-Ascorbic Acid. The product is fragrance-free; the scent is an indicator of the raw, potent ingredient at work.
    • Texture: It has a very lightweight, watery, and slightly oily texture due to its dual-phase formula. It is designed to absorb quickly into the skin. You may notice it feels slightly gritty upon application; this is due to the high concentration of the powder-form Vitamin C and is normal.
    • Feel: Upon application, you may experience a mild tingling or warming sensation on the skin. This is a common and expected reaction as your skin adjusts to the potent active ingredient. The serum absorbs to a non-greasy finish, leaving skin feeling smooth and prepped for moisturizer.

    FAQs about COSRX Advanced The Vitamin C 23 Serum 20ml

    • COSRX Advanced The Vitamin C 23 Serum 20ml

      Most common questions about COSRX Advanced The Vitamin C 23 Serum 20ml

      Is it normal for the serum to be yellow?
      Yes, a pale yellow tint is the natural colour of this high-concentration formula. However, if the serum turns dark orange or brown, it means the Vitamin C has oxidized and lost its potency. At that point, you should discard the product. Always store it in the fridge to slow this process.

      Why does this serum tingle when I apply it?
      A mild tingling sensation is a normal response to the very low pH and high concentration of L-Ascorbic Acid. This feeling should subside as your skin's tolerance builds. If the tingling is severe or accompanied by prolonged redness or burning, discontinue use.

      Can I use this serum if I have sensitive skin?
      This is a very high-strength formula and is not recommended for those with highly sensitive or compromised skin. If you have sensitive skin and want to try it, a thorough patch test is essential, and you should start with use only once or twice a week. COSRX also offers a lower-strength Vitamin C 13 serum which may be a better starting point.

      How long does a bottle last once opened?
      To ensure maximum potency, it is strongly recommended that you use the entire bottle within 2 months of opening it. Keeping it properly sealed and refrigerated is key to preserving its effectiveness for this duration.

      Why do I have to keep it in the refrigerator?
      Pure Vitamin C (L-Ascorbic Acid) is a highly unstable ingredient that degrades quickly when exposed to light, air, and heat. Storing the serum in the cool, dark environment of a refrigerator significantly slows down the oxidation process, keeping the formula fresh and effective for longer.
