2. Apply toner if it is part of your skincare routine.

3. Take a few drops of COSRX Vitamin C 13 Serum.

4. Gently spread the serum over your face using your fingertips.

5. Pat lightly until absorbed.

Important usage and storage instructions:

• If you are new to Vitamin C, start with a few applications per week and gradually increase according to your skin's tolerance.

• Perform a patch test before regular use.

• Avoid applying to broken or irritated skin.

• The brand recommends storing the serum upright in a refrigerator at 3°C to 10°C.

7. Who Is It Best For?

COSRX The Vitamin C 13 Serum is suitable for people who want to address the appearance of:

• Dull and tired-looking skin

• Uneven skin tone

• Dark spots and discoloration

• Post-acne marks

• Early visible signs of ageing

• Rough-looking skin texture

• Loss of natural-looking radiance

It is particularly useful for skincare users who want to introduce Vitamin C into their routine without starting with the stronger 23% formula.

8. Skin Type Compatibility

According to COSRX, Vitamin C 13 Serum is suitable for all skin types. However, Vitamin C can cause irritation in some people, especially those with sensitive skin.

• Normal Skin: Helps support a brighter and more even-looking complexion.

• Oily Skin: Its lightweight, water-based texture absorbs quickly without a heavy finish.

• Combination Skin: Can be applied to the face as part of a balanced skincare routine.

• Sensitive Skin: Introduce gradually and patch test first because 13% pure Vitamin C may cause tingling or irritation.

If you experience persistent redness, burning or discomfort, discontinue use.

9. Finish & Coverage

Finish: Lightweight, natural and non-sticky.

Texture: Watery, fast-absorbing serum.

Coverage: Not applicable. This is a skincare treatment, not a makeup product.

The formula has a slight yellowish tint, which COSRX associates with its pure Vitamin C content. Its lightweight consistency makes it easy to layer under moisturiser and sunscreen.
