COSRX The Hyaluronic Acid 3 Serum is a high-performance hydration serum formulated with 3% hyaluronic acid and barrier-supporting skincare actives to deliver deep moisture, plumpness and overall skin comfort.

The 3% Sodium Hyaluronate used here is low molecular weight, allowing for deeper absorption than standard hyaluronic acid. It's paired with a Natural Moisturising Factor amino acid complex (serine, alanine, glycine and more) and a skin-identical trio of Ceramide NP, cholesterol and phytosphingosine — mirroring the skin's own barrier lipids for lasting resilience.

Why you'll love it:

Sodium Hyaluronate (3%): Low molecular weight, concentrated humectant that attracts and retains moisture for lasting hydration.
Natural Moisturising Factor (Amino Acid Complex): Supports the skin barrier and improves moisture retention.
Ceramide NP, Cholesterol & Phytosphingosine: A skin-identical trio that reinforces the skin barrier and helps lock in hydration.
Lactic Acid: Gentle exfoliation alongside deep hydration for a smoother, healthier-looking complexion.

Perfect for:

Dry or dehydrated skin needing an intensive hydration boost
Skin that feels tight, flaky or textured, especially under makeup
Those looking for a reliable daily serum to support barrier and moisturise deeply
All skin types; particularly useful for sensitive or barrier-compromised skin
