COSRX The Vitamin C 23 Serum
COSRX The Vitamin C 23 Serum is a concentrated vitamin C treatment designed to improve the appearance of dullness, uneven skin tone, dark spots, and early signs of aging. Its formula contains 23% pure vitamin C, also known as ascorbic acid, alongside antioxidant and skin-conditioning ingredients.
Unlike a low-concentration beginner serum, this formula contains a high percentage of pure vitamin C. It may be worth considering for people who already have experience using vitamin C products and want a more concentrated option for their skincare routine.
Key Benefits of COSRX The Vitamin C 23 Serum
Helps brighten dull-looking skin
Vitamin C is an antioxidant ingredient commonly used in skincare to improve the appearance of dull skin and support a more radiant-looking complexion.
Helps improve the appearance of dark spots
With regular use and suitable sun protection, vitamin C may help improve the appearance of uneven pigmentation and post-blemish marks. Results vary depending on the cause and depth of the pigmentation.
Supports a more even-looking skin tone
This serum may suit routines focused on visible uneven skin tone and areas that look darker than the surrounding skin.
Helps care for early signs of skin aging
Vitamin C provides antioxidant support, while the formula also contains ingredients such as adenosine and skin-conditioning agents. The serum can complement a routine focused on the appearance of fine lines and uneven texture.
Provides skin-conditioning support
Panthenol, sodium hyaluronate, and allantoin help condition the skin and support hydration. However, the high concentration of vitamin C may still cause irritation for some users.
Who Should Consider COSRX The Vitamin C 23 Serum?
This serum may suit people concerned about:
- Dull or tired-looking skin
- Uneven-looking skin tone
- Visible dark spots and post-blemish marks
- Rough-looking skin texture
- Early visible signs of aging
Because it contains 23% pure vitamin C, beginners and people with sensitive skin should be particularly cautious. Start with a patch test and introduce the serum gradually. If your skin is already irritated or your skin barrier is compromised, wait until it has recovered before considering a high-strength active.

How to Use
How to Use COSRX The Vitamin C 23 Serum
COSRX The Vitamin C 23 Serum contains a high concentration of pure vitamin C. Introduce it carefully, particularly if you have never used a concentrated vitamin C serum before.
Step-by-Step Application
- Cleanse your face: Start with a gentle facial cleanser and pat your skin dry.
- Apply toner if needed: If you use a toner, apply it after cleansing and before the serum.
- Mix the formula gently: Follow the manufacturer’s directions for preparing the product before application.
- Apply the serum: Use approximately 2 to 3 drops over the face, avoiding the eyes, lips, and irritated areas.
- Pat gently: Spread the serum gently and allow it to absorb.
- Apply moisturiser: Follow with a moisturiser suited to your skin type.
- Use sunscreen during the day: Finish your morning routine with broad-spectrum sunscreen rated SPF 30 or higher.
How Often Should You Use It?
Follow the product label. If you are new to high-strength vitamin C, start gradually and monitor your skin’s response before increasing frequency. Do not continue daily use if persistent irritation develops.
Important Precautions
- Patch-test the serum before regular use.
- Avoid applying it to broken, irritated, or freshly exfoliated skin.
- Do not introduce several strong active ingredients at the same time.
- COSRX advises avoiding use alongside copper peptide products and other high-concentration actives such as retinol. Consider using these products at different times of day rather than layering them together.
- Use broad-spectrum sunscreen during the day.
- Stop using the serum if you experience persistent burning, significant redness, swelling, or irritation.
- Follow the packaging instructions for storage and the recommended period of use after opening. Check the serum’s colour, smell, and texture if you are concerned about changes, and do not use it if it appears spoiled.
