About this item

  • Deep drink for thirsty skin: 3% sodium hyaluronate hydrates at different levels, boosting skin moisture by over 200% in tests.
  • Locks moisture in: ceramide NP and amino acids (like the skin's natural moisture factors) support the barrier so hydration lasts.
  • Weightless, silky feel: spreads easily and sinks in fast with a dewy look, never sticky, heavy or tacky.
  • Smoother base for everything: hydrated skin looks plumper and lets makeup glide on without catching dry spots.
  • Made with sensitive skin in mind: gentle, non-comedogenic formula; apply 2-3 drops to slightly damp skin after cleansing.

Description

COSRX The Hyaluronic Acid 3 Serum gives your skin a deep drink of moisture that lasts all day. This gentle serum uses 3% sodium hyaluronate to help dry, thirsty skin feel soft and look fresh again. Perfect for all skin types, it helps strengthen your skin's natural barrier while adding a plump, dewy look. The light, smooth formula sinks in fast without feeling sticky or heavy. Give your skin the care it needs with this simple yet mighty hydration helper.

Why Your Skin Will Love This Hydration Helper

When your skin feels tight, rough, or just not its best, it's often asking for one thing - moisture. The COSRX Hyaluronic Acid 3 Serum is like a tall glass of water for thirsty skin. It boosts your skin's moisture right away - by over 200% according to tests! But it doesn't just add water and leave. This smart serum locks that moisture in place with special barrier-building ingredients.

The magic comes from the 3% sodium hyaluronate that works at different levels in your skin. Unlike some face products that just sit on top, this one helps hydrate deep down. Your skin will feel softer, look smoother, and makeup will go on better too. It's the perfect first step after washing your face, giving skin the moisture base it needs to look its best.

The Good Stuff Inside

What makes this serum special is its mix of skin-loving ingredients. The star is sodium hyaluronate - a form of hyaluronic acid that holds up to 1,000 times its weight in water. At 3%, it's the perfect amount to help skin look plump without being too heavy. But there's more to love:

  • Amino acids that work like your skin's natural moisture factors
  • Ceramide NP to help strengthen your skin's protective barrier
  • Soothing ingredients that help calm sensitive skin
  • A blend of humectants that draw moisture to your skin

The formula is made to work for all skin types. Even if your skin tends to be sensitive, the gentle, caring mix of ingredients helps add moisture without causing upset. It's a simple, kind way to help your skin look and feel its best.

How It Feels On Your Skin

Nobody wants skincare that feels sticky, heavy, or just plain weird. That's why we love how this serum feels when you put it on. The texture is light and silky - not thick or gooey like some other serums. It spreads easily and sinks in fast, leaving your skin feeling soft and smooth, not tacky or wet.

Right after you put it on, you'll notice your skin feels more hydrated and looks dewier. Over time, with regular use, many people see their skin texture improve too. Rough patches feel smoother, and your skin has that healthy bounce that comes with good hydration. It creates the perfect base for the rest of your skincare or makeup, helping everything go on more evenly without catching on dry spots.

How To Make It Part Of Your Routine

Adding this serum to your daily skin routine is super easy. Here's how to get the most out of it:

  • Wash your face with a gentle cleanser
  • While your skin is still a bit damp, put 2-3 drops in your palm
  • Gently press the serum onto your face and neck
  • Follow with your favorite moisturizer to seal in all that goodness

You can use it twice a day - morning and night. In the morning, it helps prep your skin for the day and makes your makeup look better. At night, it works while you sleep to help restore moisture. The small bottle may look tiny, but a little goes a long way. Most people find it lasts 1-2 months with regular use, making it a good value for such a helpful product.

Who This Serum Is Perfect For

While everyone's skin can benefit from good hydration, this serum is especially helpful for certain skin situations:

  • Dry or dehydrated skin that needs a moisture boost
  • Skin that feels tight after washing
  • Winter-worn skin fighting against indoor heating
  • Skin that looks dull and needs a fresh glow
  • Makeup that goes on patchy due to dry spots

No matter your age, helping your skin stay hydrated is one of the best things you can do for it. This serum works well for people in their 20s all the way through their 50s and beyond. The light formula won't clog pores, so even if you tend to get some oily spots, you can still use it all over or just in the dry areas that need some extra help. COSRX has made a simple but powerful product that fits into almost any skincare routine.

Ready to give your skin the hydration hug it's been waiting for? Add COSRX The Hyaluronic Acid 3 Serum to your skincare routine today and feel the difference that deep, lasting moisture can make. Your skin will thank you with a soft, smooth, glowing look that feels as good as it looks. Treat yourself to this little bottle of hydration magic - your future skin will be so glad you did!

How to Use

Apply 2-3 drops of the product onto damp skin after cleansing, pressing gently into the face and neck while avoiding the eye area. For optimal results, seal with a ceramide moisturizer to enhance occlusion and barrier support. Use consistently twice daily — in the morning and evening. Store in a tightly closed container at room temperature (15-25°C) to prevent oxidation, and ensure proper usage within 1-2 months for maximum efficacy. Suitable for dry, dehydrated, and sensitive skin types, the product can be incorporated into a year-round routine, particularly in dry seasons or climates, with layering under other lightweight products during summer. Always follow with sun protection during the day.
