COSRX The Hyaluronic Acid 3 Serum 20ml, 2 Pack

Features

COSRX The Hyaluronic Acid 3 Serum 20ml, 2 Pack delivers high-density, intense hydration to dry and parched skin. Formulated with low molecular weight hyaluronic acid, its small particles allow for efficient absorption to help retain long-lasting moisture. The serum features a watery, firm, and elastic texture that applies smoothly over the skin without leaving a sticky residue, providing a refreshing finish.

Benefits

This serum provides powerful moisture delivery, relieving skin tightness and restoring moisture levels deep within the skin. It provides a plumping hydration effect that keeps skin feeling hydrated and looking supple all day long. Suitable for all skin types, including sensitive and combination skin, it can also be layered multiple times on severely dry days to serve as an intensive hydration pack.

Main Ingredients and their effects

Low Molecular Hyaluronic Acid (Sodium Hyaluronate 3%): Provides intense hydration by penetrating efficiently due to its small molecular size, helping to lock in moisture and plump the skin.

Natural Moisturizing Factors (NMF / Amino Acids Complex): Includes 12 essential moisture-replenishing agents such as Sodium PCA, Betaine, PCA, Serine, Alanine, Glycine, Glutamic Acid, Lysine HCl, Threonine, Arginine, and Proline to reinforce and strengthen the skin barrier's moisture capacity.

Ceramide NP: Works in harmony with the moisture complex to lock in hydration and protect the skin barrier against dryness.

Clinical test results

In clinical trials conducted by the Dermacosmetic Dermatology Research Institute, a single application showed a 223% increase in surface skin moisture and a 16% increase in deep skin hydration (tested on 20 women aged 20–60 from August 1 to August 16, 2022). In a 4-week consumer perception evaluation with the same group, 100% of participants reported an improvement in inner dryness, a plumping sensation from increased hydration, and an all-day moisturized feel. Primary skin irritation testing has also been completed on sensitive skin (tested on 30 subjects from November 28 to December 12, 2022).

Usage instructions

After cleansing and applying toner, apply an appropriate amount of serum directly onto the face. Use your fingertips to gently roll and spread the product in an outward direction from the center of the face until fully absorbed. Follow with your preferred moisturizer. For extra dry skin, apply multiple layers before bed for an intensive sleeping pack effect.
