COSRX The Hyaluronic Acid 3 Serum is a concentrated moisturizing serum for dry, dehydrated and tight-feeling skin. The formula contains 3% sodium hyaluronate with amino acids, ceramide NP and other skin-conditioning ingredients. Its fluid texture adds a focused hydration step before moisturizer, helping skin feel softer and look more plump. The 20mL dropper bottle makes it easy to dispense the serum without treating it as a rinse-off mask or exfoliating toner.

A hydrating serum is a leave-on treatment applied between cleansing or toning and moisturizer. It delivers a focused moisturizing formula in a fluid format, rather than acting as a cleanser or a sunscreen. It can be useful when dry-feeling skin needs an extra layer beneath a cream.
This COSRX serum centers on 3% sodium hyaluronate, a form of hyaluronic acid. Amino acids and ceramide NP complement its moisture-focused formula. Apply a few drops and gently spread them over the face, then follow with moisturizer when needed. Its purpose is to improve hydration and the appearance of plumpness without introducing an exfoliating step.
3% sodium hyaluronate with amino acids and ceramide NP
The formula combines a highlighted hyaluronic-acid ingredient with several supporting humectants and lipids. The dropper format is intended for controlled facial application, allowing the serum to sit under a moisturizer rather than replacing the rest of a skincare routine.
- 3% sodium hyaluronate: Sodium hyaluronate is the hyaluronic-acid ingredient listed at 3% in the formula. It anchors the serumβs moisture-focused identity and distinguishes it from a general toner or lightweight facial mist.
- Amino-acid blend: Serine, alanine, glycine, glutamic acid, lysine, threonine, arginine and proline appear in the ingredient list. These are included with other conditioning ingredients rather than as a separate powder or mixing step.
- Ceramide and lipids: Ceramide NP, cholesterol, phytosphingosine and hydrogenated lecithin support the formulaβs skin-conditioning structure. They complement the water-binding ingredients in a serum intended for dry-feeling skin.
- Additional humectants: Glycerin, betaine, sodium PCA, sodium lactate and PCA help round out the moisturizing formula. The combination provides more context than describing the product as hyaluronic acid alone.
- 20mL dropper bottle: The bottle dispenses a few drops for a facial application. The full formula includes alcohol, so this serum should not be selected on the assumption that it is alcohol-free; check the ingredient declaration against your preferences.
A supple plump-looking finish for moisture-depleted skin
This serum focuses on how hydrated skin looks and feels. It can complement a moisturizer when the skin feels dry or tight, offering a dedicated moisture step without the abrasive texture of a scrub or the routine changes needed for an acid exfoliant.
- Focused hydration: The humectant-rich formula helps replenish moisture in dry-feeling skin. Apply it before a cream so that the routine includes both a fluid hydrating layer and the moisturizing finish that suits your needs.
- Plumper-looking skin: Hydration can help skin look less depleted and more supple. The serum is intended to improve this moisture-related appearance rather than promise a permanent change to facial volume.
- Smoother-feeling dryness: Adding moisture helps soften the feel of dry surface texture. Gentle application is sufficient; there is no need to massage aggressively or use a cleansing device with the serum.
- Comfort under moisturizer: A fluid layer can make it easier to tailor a routine when a moisturizer alone does not feel hydrating enough. Let the serum absorb, then continue with the products appropriate to the time of day.
- A non-exfoliating treatment step: The product is designed around hydration rather than resurfacing. It offers a focused option for routines that need moisture without adding another strong exfoliating treatment to the same session.
