Hydrium Triple Hyaluronic Moisture Ampoule

COSRX Hydrium Triple Hyaluronic Moisture Ampoule is a thick, cushiony hydrating serum for skin that drinks everything and still feels tight by lunchtime. Two or three drops leave the face supple and plumper-looking straight away, without the heavy slip of a rich cream.

What it actually does

• Plumps on contact. COSRX describes the plumping as immediate, with the hydration side of it lasting through the day.
• Hydrates intensely without a greasy film. The texture is viscous and serum-like, but the finish it leaves is light and fresh rather than slick.
• Supports the barrier. The brand lists recovery and protection of the skin barrier among the benefits, not just surface moisture.
• Aimed at tight, tired, flaky skin. Dryness, dehydration and that fatigued, crepey look are the three concerns it is built around.
• A good answer if you dislike thick creams. COSRX specifically recommends it for people who need serious hydration but can't stand rich textures.

How to use

1. Two or three drops is the dose. More than that just sits on the surface.
2. Keep it off the eyes and mouth. Place drops across the cheeks, forehead and chin instead.
3. Spread evenly, then massage. Work it in until it has fully absorbed — that is how the brand says to get the most out of it.
4. Apply to slightly damp skin. Hyaluronic serums behave better with water underneath them, so use it after your toner rather than on a bone-dry face.
5. Seal it. Follow with a moisturiser, and SPF in the morning.

Questions

Is it greasy?

No. The serum itself is thick, but COSRX is clear that the finish is light and fresh with no oily residue, which is why it suits people who avoid rich products.

Can I skip moisturiser and just use this?

We'd keep the moisturiser. An ampoule delivers water into the skin; a cream is what stops it leaving again. In a dry or air-conditioned environment, skipping the final step undoes a lot of the work.

Morning, night, or both?

Either works. Hydration isn't light-sensitive, and the light finish means it sits fine under makeup if you use it in the morning.

How long does delivery take?

Delivery takes 3 to 21 working days, depending on availability. Items on hand ship fastest; items we bring in for your order take longer. Working days exclude weekends and official holidays.

How do I pay, and what if it arrives damaged?

Payment is by credit card, debit card, Instapay or mobile wallet — no cash on delivery. If the item arrives defective, damaged or expired, report it within 1 day of delivery with a photo; those are the only cases we accept, and the refund goes to your original payment method within 15–30 days.
