[cosrx] the hyaluronic acid 3 serum 20ml

The Science of “Hyper Hydration”
The COSRX Hyaluronic Acid 3 Serum solves the problem of “chronic dehydration and sagging.” Most HA serums use a concentration of 1% or less; by increasing this to 3%, COSRX has created a serum that acts like an “injectable grade” topical treatment. By utilizing low molecular weight molecules, the serum doesn’t just coat the skin—it physically penetrates the barrier to pull moisture into the intercellular spaces, resulting in an immediate “lift” and glow.

Key Ingredients & Benefits:

3% Sodium Hyaluronate: A high intensity concentration that binds 1,000 times its weight in water, “filling in” fine lines and wrinkles from the inside out.

Ceramide NP: Essential lipids that “glue” skin cells together, repairing the moisture barrier so the hydration doesn’t evaporate.

Natural Moisturizing Factors (NMF): A complex of amino acids that mimic the skin’s natural hydration system to improve long term resilience.

Panthenol (Pro Vitamin B5): Provides a dual action of soothing redness and attracting even more moisture to the skin’s surface.

Betaine: Derived from sugar beets, it helps the skin adapt to moisture losses and prevents irritation.

Why Your Customers Will Love It:

The “Instant Bounce” Result: Skin feels noticeably more “springy” and firm to the touch within seconds of application.

Soothing After Actives: It is the perfect “cool down” serum to use after high strength Retinol or Vitamin C treatments to prevent flaking.

Elegant Texture: Despite its high concentration, it has a sophisticated, silky slip that absorbs without a heavy, “tacky” residue.

Clinical Precision: Part of the COSRX “The RX” line, this serum is designed with minimalist, high purity ingredients for maximum skin compatibility.

How to Use:

Prep: After cleansing, apply 2–3 drops to damp skin. (Hyaluronic acid needs moisture to pull from; applying it to bone dry skin can actually cause temporary dryness).

Apply: Massage in upward motions across the face and neck.

Seal: Immediately follow with a moisturizer (like the Hyaluronic Acid Intensive Cream) to “lock” the water into the skin.

Pro Tip: For a “Red Carpet Glow,” mix one drop of this serum into your liquid foundation. It will prevent the makeup from settling into fine lines and keep your skin looking “glassy” all day.
