COSRX Hyaluronic Acid Moisture Ampoule 3X, 1.35 fl.oz — Triple HA Hydration, Lightweight Non-Sticky Serum

COSRX 3X Hyaluronic Acid Moisture Ampoule is a lightweight, water-based serum that layers three forms of hyaluronic acid to deliver lasting hydration and a plumper-looking complexion.

This ampoule combines Sodium Hyaluronate, Hyaluronic Acid, and Hydrolyzed Hyaluronic Acid with 1,000 ppm panthenol to hydrate, soothe, and help restore skin elasticity without heaviness or stickiness. Designed for dry to combination skin types and formulated under COSRX's gentle-skin standards, it’s intended to be a daily moisture booster that fits easily into morning or evening routines.

How does this ampoule hydrate without feeling heavy?

The formula is water-based and absorbs quickly, so it delivers moisture without leaving a greasy film. Multiple molecular weights of hyaluronic acid reach different layers of the skin to retain water where it’s needed most.

• Three hyaluronic acid types for multi-depth hydration
• Lightweight, non-sticky texture that layers under moisturizers
• Fast absorption suitable for combo and oily-prone zones

Can this product help my skin look plumper and less tight?

By attracting and holding water, hyaluronic acids can temporarily improve surface plumpness and reduce the appearance of tightness caused by dehydration. Panthenol (pro-vitamin B5) supports a soothing effect so skin feels more comfortable after application.

• Hydration helps smooth the look of fine dehydration lines
• Panthenol calms irritated or dry-feeling areas
• Recommended follow-up: seal with your regular moisturizer for best results

How should I use the COSRX 3X Hyaluronic Acid Moisture Ampoule in my routine?

Apply the ampoule after cleansing and toning while skin is slightly damp to maximize water retention. Use a few drops, gently patting into face and neck, then lock in moisture with your usual cream or sunscreen in the morning.

• Step order: cleanse → tone → ampoule → moisturizer → SPF (day)
• Use morning and/or night depending on dryness level
• Works well under serums or mixed into moisturizer for extra hydration

Is this product suitable for sensitive or irritation-prone skin?

COSRX formulates to minimize irritation: the ampoule is hypoallergenic and dermatologist-tested with no parabens, sulfates, phthalates, or animal testing. Still, perform a patch test if you have very reactive skin or known sensitivities.

• Dermatologist-tested and formulated for gentle use
• Free from common irritants like sulfates and parabens
• Patch test recommended for highly reactive skin

Who is this for: The COSRX 3X Hyaluronic Acid Moisture Ampoule suits anyone seeking an effective, low-irritation hydration boost—especially those with dry, dehydrated, or combination skin who want a lightweight layerable serum. It’s also a smart add-on for anti-aging regimens that need moisture to support elasticity and texture, and for daily use to maintain comfortable, plump-feeling skin.
