COSRX Hydrium Triple Hyaluronic Moisture Ampoule 40ml — Triple HA + Panthenol Hydrating Serum, Lightweight Non-Sticky

COSRX Hydrium Triple Hyaluronic Moisture Ampoule is a concentrated, water-based serum formulated with three forms of hyaluronic acid and panthenol to hydrate, plump, and calm dry or sensitive skin.

This ampoule delivers targeted moisture using a blend of Sodium Hyaluronate, Hyaluronic Acid, and Hydrolyzed Hyaluronic Acid plus 1,000 ppm panthenol to support skin barrier comfort. Lightweight and non-sticky, its slightly viscous texture layers easily under creams or makeup and suits routines that need an effective hydration boost without heavy residue.

How does this ampoule hydrate different layers of the skin?

The formula combines three molecular weights of hyaluronic acid to reach multiple skin depths: low‑, medium‑, and high‑molecular variants attract and retain water at surface and deeper layers. Panthenol complements hydration by soothing and supporting barrier repair, helping the moisture stay locked in longer.

• High-molecular HA: immediate surface hydration and smoothing
• Medium-molecular HA: moisture retention in mid layers for plumping
• Low-molecular/hydrolyzed HA: penetrates deeper for lasting fullness
• 1,000 ppm panthenol: soothes irritation and supports barrier resilience

Will this ampoule feel heavy or leave a sticky finish?

COSRX designed the Hydrium ampoule with a water-based, slightly viscous texture that absorbs quickly without tackiness. It provides noticeable hydration while remaining lightweight, so it layers smoothly with serums, moisturizers, or sunscreen.

• Quick-absorbing formula that avoids heaviness
• Non-sticky finish suitable for morning and evening use
• Works well under makeup as a hydrating base
• Leaves skin pliable, not greasy

Can I use this ampoule with anti-aging products or sensitive skin routines?

The ampoule is complementary to anti-aging regimens because hydration improves elasticity and the appearance of fine lines. It’s formulated to be hypoallergenic and free of parabens, sulfates, phthalates, and animal testing, making it a suitable hydration step for many sensitive skin routines.

• Supports elasticity when paired with active anti-aging ingredients
• Dermatologist-tested and hypoallergenic-friendly
• Free from parabens, sulfates, phthalates, and animal testing
• Recommended to patch-test when combining potent actives

How should I incorporate this ampoule into my daily skincare routine?

Use the ampoule after cleansing and toning, while skin is slightly damp, to maximize hyaluronic acid’s water-binding effect. Apply a few drops, press lightly to encourage absorption, then follow with a moisturizer to seal in hydration; it works in both AM and PM routines.

• Step 1: Cleanse and tone skin
• Step 2: Apply 2–3 drops to damp skin and pat gently
• Step 3: Follow with moisturizer and sunscreen (AM) or richer cream (PM)
• Use daily for consistent hydration benefits

Who is this for: The COSRX Hydrium Triple Hyaluronic Moisture Ampoule is ideal for anyone seeking a dependable hydration boost—dry, dehydrated, combination, or sensitive skin types will benefit most. It's especially useful for people who want a lightweight, layering-friendly serum to plump skin and support barrier comfort without heavy oils or problematic preservatives. Those using anti-aging products can add this ampoule to enhance elasticity and minimize the look of fine lines through improved moisture retention.
