Cosrx The Hyaluronic Acid 3 Serum

COSRX The Hyaluronic Acid 3 Serum is a hydration-focused serum built around 3% sodium hyaluronate, joined by ceramide NP, cholesterol, and a blend of amino acids that mirror skin's own moisture-barrier components. The lightweight, water-based texture is designed to replenish moisture without feeling heavy, making it a straightforward daily hydrator for most skin types.

Key Benefits

• Delivers concentrated hydration with 3% sodium hyaluronate.
• Supports the moisture barrier with ceramide NP, cholesterol, and fatty acids.
• Contains amino acids and PCA that mimic skin's natural moisturizing factors.
• Lightweight, fast-absorbing texture layers easily under other products.
• Suitable for daily use on dehydrated or moisture-barrier-compromised skin.

When to Use

Use morning and/or evening after cleansing and toner, before heavier creams or oils. Suited to skin experiencing dehydration or barrier stress.

How to Use

Apply 2-3 drops to clean, toned skin. Spread over the face and neck, pat gently until absorbed, then seal with a moisturizer.

Key Ingredients

• Sodium Hyaluronate (3%): a humectant that draws and holds moisture in the skin.
• Ceramide NP: a skin-identical lipid that helps reinforce the moisture barrier.
• Cholesterol: works alongside ceramides to support barrier structure.
• Sodium PCA: a natural moisturizing factor that helps skin retain water.

Precautions

Patch test before first use. Avoid direct eye contact and discontinue use if persistent irritation occurs. Store away from direct sunlight and heat.
