COSRX The Vitamin C 13 Serum 20ml (Renewal Edition), 13% Pure E & Hyaluronic Acid, Facial for Fine Lines, Uneven Skin Tone Dull Skin, Korean Skincare

📖 PRODUCT COMBINATION GUIDANCE 📖 Our Vitamin C 13 Serum contains a high concentration of pure Vitamin C. For optimal performance and ingredient stability, we recommend avoiding concurrent use with highly concentrated peptide-based products, including our Blue Peptide Serum and Blue Peptide Cream, as well as other high-strength actives such as Retinol products and our Niacinamide 15 Serum. We recommend applying these products at different times of day rather than within the same routine. For example, use Vitamin C 13 Serum in the morning and Blue Peptide Serum or Blue Peptide Cream in the evening. DAILY VITAMIN C BOOST FOR RADIANT SKIN: Formulated with 13% Pure Vitamin C to help improve the look of dull, tired skin and uneven skin tone. This lightweight serum absorbs quickly without stickiness, leaving skin looking smoother, brighter and healthier every day. POWERFUL ANTIOXIDANT COMPLEX: Combines Pure Vitamin C, Tocotrienol (Super Vitamin E) and Glutathione to help protect skin from environmental stressors and free radicals while supporting a more youthful-looking, luminous complexion. HELPS IMPROVE UNEVEN TONE & POST-BLEMISH MARKS: Glutathione works alongside Vitamin C to help visibly improve skin clarity, reduce the appearance of pigmentation and post-blemish marks, and promote a more even-looking complexion. HOW TO USE: Shake gently 1-2 times before use. Apply 2-3 drops once or twice daily. For daytime use, follow with an SPF 30+ sunscreen. Suitable for use around the eye area, avoiding direct contact with the eyes. Once opened, store in the refrigerator to help minimise oxidation. PATCH TEST RECOMMENDED: We recommend performing a patch test before first use. Apply a small amount to a discreet area of skin and wait 24 hours. If no irritation occurs, proceed with facial application. Discontinue use and consult a healthcare professional if irritation develops.
