Hyaluronic Acid Serum | 29.6 ml | Swanson

Swanson Hyaluronic Acid Serum is a water-based skincare serum in a 29.6 ml bottle that places hyaluronic acid on the skin surface to draw water in and hold it there. Hyaluronic acid hydrates in a different way from most ingredients: instead of coating the skin with an oily film, it acts as a water magnet inside the surface layer, which is why its effect on texture and plumpness shows quickly. It suits anyone who feels tightness and dryness after cleansing, and anyone who wants a light hydrating layer that goes before a cream rather than replacing it.

What is hyaluronic acid?

Hyaluronic acid is a long-chain polysaccharide molecule found naturally in human skin, joint fluid and the eye, belonging to the glycosaminoglycan family. Its defining trait is the ability to bind a large number of water molecules relative to its own weight, which is the basis of its role in fluid balance within the dermis. In skincare it usually appears as its sodium salt, sodium hyaluronate, because that form is more stable and allows finer control over molecular size.

What hyaluronic acid does for skin

• Immediate surface hydration: Hyaluronic acid pulls water into the stratum corneum and holds it there, easing the feeling of tightness.
• A plumper look to fine lines: Water-saturated skin reflects light more evenly, so fine lines read as less pronounced.
• Suppleness support: Water content in the surface layer is tied to how soft and pliable skin feels.
• Lightweight, non-occlusive texture: A water-based serum leaves no oily film behind.
• A base for what follows: The serum works as a first layer that helps a cream or oil spread over it.
• Suitable twice daily: It fits morning and evening use without clashing with most routines.

Active concentration and texture

Swanson Hyaluronic Acid Serum is built on a water base carrying dissolved hyaluronic acid, making it a single-active product rather than a multi-active blend. The real point of difference between hyaluronic acid serums is not percentage alone but molecular weight: larger molecules stay on the surface and form a water-holding layer, while smaller ones travel deeper into the stratum corneum. The 29.6 ml size is standard for serums and lasts an extended stretch, since one application is only a few drops.

Which skin types suit it

• Dry skin that feels tight after cleansing.
• Oily skin that needs hydration without added oils.
• Combination skin wanting one layer that works across both zones.
• Dull skin that has lost visible plumpness.
• Skin exposed to air conditioning and dry air most of the day.

Where it sits in a routine

Hyaluronic acid serum goes on right after cleansing and before moisturiser, onto skin that is still slightly damp. This order is not cosmetic detail: hyaluronic acid draws water from its surroundings, so applied to bone-dry skin in dry air it can pull moisture out of the skin instead of adding to it. Following it immediately with moisturiser seals that water inside the surface layer.

How to use

Apply a few drops to clean, slightly damp skin, spread gently over face and neck with the fingertips, then follow with your usual moisturiser. Use morning and evening, and follow the morning application with sunscreen.

FAQ

Should hyaluronic acid serum go on dry or damp skin?

Hyaluronic acid serum goes on slightly damp skin right after cleansing, because the molecule needs water around it to bind. Applying it to completely dry skin in low humidity reduces the benefit.

Does hyaluronic acid serum replace moisturiser?

Hyaluronic acid serum does not replace moisturiser, because the two do different jobs: the serum brings water into the surface layer while the moisturiser locks it in with a film that limits water loss through the skin. Used together in the right order is what produces the result.

Can it be layered with other actives?

Hyaluronic acid serum is compatible with most common actives because it is a hydrating ingredient rather than an exfoliating or modifying one. Even so, introducing one new product at a time makes it easier to track how the skin responds.

Cautions

• Patch test on a small area of the forearm before first use.
• For external use only; avoid contact with the eyes and rinse thoroughly with water if it occurs.
• Use sunscreen during the day as part of the skincare routine.
• Discontinue use if persistent redness or irritation appears and consult a dermatology clinic.
• Keep away from direct heat and out of reach of children.
