About this item

  • Brightens day by day: 13% pure vitamin C helps fade dark spots and post-breakout marks for a more even, radiant tone.
  • Antioxidant team-up: tocotrienol (super vitamin E) joins vitamin C to help protect skin from daily stress.
  • Supports firmness: vitamin C supports natural collagen, helping smooth rough texture and shrink the look of pores.
  • Comfort in the formula: hyaluronic acid pulls in moisture and allantoin calms, so it works hard yet feels soft on skin.
  • Light daily texture: clear, water-based serum soaks in fast without stickiness and suits dry, oily and combination skin alike.

Description

COSRX The Vitamin C 13 Serum brightens your skin with gentle yet powerful ingredients. This light, clear formula helps fade dark spots and even out skin tone while giving your face a healthy glow. Made with 13% pure vitamin C and supporting ingredients like super vitamin E and hyaluronic acid, this serum works hard but feels soft on your skin. It's perfect for all skin types and helps with everything from rough texture to visible pores. The simple, clean formula skips harsh additives and focuses on what works. Give your skin the daily boost it needs with this friendly, effective vitamin C serum.

What Makes This Vitamin C Serum Special

This isn't just any vitamin C product. COSRX The Vitamin C 13 Serum stands out because it brings together pure vitamin C (13%) with skin-loving helpers like super vitamin E and hyaluronic acid. These work as a team to brighten your skin without being harsh. The light, water-based texture soaks in fast without feeling sticky, making it nice for both dry and oily skin types. Unlike some vitamin C products that can feel harsh, this one keeps a skin-friendly balance. It helps fade dark spots and makes your skin look more even and smooth. The best part? It's made without fragrances, parabens, sulfates, or mineral oils that might upset your skin.

How This Serum Helps Your Skin

When you use this serum, you're giving your skin several gifts at once. First, it helps fade those stubborn dark spots and marks that stay after breakouts. The vitamin C works to even out your skin tone day by day. You'll also notice smoother skin texture as it helps your skin make more collagen - that's what keeps skin plump and firm. The serum shrinks the look of pores while giving antioxidant protection against daily stress. For extra care, it has hyaluronic acid that pulls moisture into your skin, and allantoin that calms any irritation. This mix of benefits means your skin gets both instant help and long-term care.

  • Fades dark spots and evens skin tone
  • Smooths rough texture and shrinks visible pores
  • Protects skin with antioxidants
  • Boosts moisture and soothes skin
  • Supports natural collagen production

Who This Serum Works Best For

The gentle yet effective formula makes this serum a good match for almost everyone. If you have normal, oily, dry, or combo skin, you'll find it works without causing problems. Even those with sensitive skin often do well with it, though the 13% vitamin C might be a bit strong if your skin is very reactive. It's perfect if you want to brighten your skin, fade marks, or just keep your skin looking fresh and healthy. People in their mid-20s and up love it for fighting early signs of aging, while younger folks use it to help with marks left from breakouts. The lightweight feel makes it great for humid weather, but it's hydrating enough for colder months too.

  • All skin types including oily, dry and combination
  • Ages 18+ for prevention and visible improvements
  • Great for those with uneven tone or rough texture
  • Works in all seasons and climates

How to Make the Most of Your Serum

Using this serum is simple, but a few tips will help you get the best results. Start with clean, dry skin - wash your face and pat it dry, then apply any toners you use. Give the bottle a light shake before using it. Place 3-5 drops on your fingers and gently press the serum onto your face and neck. You can use small, light motions to help it soak in. Let it dry for a minute, then follow with your favorite moisturizer. In the morning, always finish with sunscreen, as vitamin C works even better when your skin is protected from the sun. For best results, store the bottle in your fridge after opening - this keeps the vitamin C fresh and working at its best.

  • Use morning and/or night on clean skin
  • Apply before moisturizer, after cleansing and toning
  • Store in the refrigerator to keep it fresh
  • Always use SPF during the day

What to Expect When Using This Serum

When you first start using this vitamin C serum, you'll notice it feels light and soaks in quickly. Many people see a small boost in brightness right away as it wakes up tired skin. The real magic happens over time - after a few weeks of daily use, dark spots begin to fade and skin tone looks more even. Many users see smoother texture and smaller-looking pores after about four weeks. The serum helps reduce redness too, giving your skin a calm, balanced look. Some people notice the vitamin C has a light smell that fades quickly. Remember that good things take time - stick with it for at least a month to see how your skin transforms with this gentle daily care.

Ready to help your skin look its brightest? Add COSRX The Vitamin C 13 Serum to your daily routine and watch as dark spots fade and your natural glow returns. Your skin deserves this gentle, effective care. Treat yourself to the calm, confident feeling of skin that looks and feels its best!

How to Use

To achieve the best results, start by cleansing and toning your skin. Shake the bottle lightly before each use. Apply 3-5 drops to your face and neck, then gently massage in an inward-outward motion. Follow with a moisturizer and SPF during the day. Use daily in the morning and evening. For storage, refrigerate after opening to maintain stability and antioxidant potency, which lasts approximately 120 hours in cool storage. The product typically lasts 2-3 months with daily use of 20ml. Incorporate into your routine by using Vitamin C and Hyaluronic Acid in the morning, with SPF, and considering a retinol substitute 3 times weekly at night. Avoid using high-strength exfoliants simultaneously to prevent irritation, especially for sensitive skin types.
