Naturium Quadruple Hyaluronic Acid Serum 5% — 1 oz Hydrating, Fragrance-Free Gel for Plumping & Smoothing

Naturium Quadruple Hyaluronic Acid Serum 5% is a lightweight, fragrance-free face serum that layers four molecular weights of hyaluronic acid to visibly hydrate and smooth skin.

This serum combines a 5% hyaluronic acid concentration with multiple molecular sizes so moisture reaches both surface and deeper layers for improved skin texture and a plumper appearance. The gel-like formula sinks in quickly, works well under moisturizers and makeup, and is formulated without fragrance, parabens, or gluten—making it suitable for a wide range of skin types including sensitive and aging skin when patch-tested first.

How does this serum hydrate different layers of my skin?

Naturium’s approach uses four molecular weights of hyaluronic acid so hydration isn't limited to the outermost layer. Smaller molecules can penetrate deeper to support internal moisture, while larger molecules sit on the surface to lock in hydration and smooth fine lines.

• 4 molecular weights provide layered hydration from surface to deeper layers
• 5% total hyaluronic acid delivers noticeable moisturization without heaviness
• Gel texture attracts and retains water for plumpness and elasticity
• Fragrance-free formulation reduces irritation risk for sensitive skin

Will this serum help with fine lines and texture?

Regular use can make skin look smoother and more resilient by replenishing moisture where fine lines form. Hydrated skin reflects light better and appears more even; combined with a consistent routine, the serum supports a plumper look and softer texture.

• Hydration plumps creases and visibly softens fine lines
• Improved moisture balance can enhance overall skin smoothness
• Works under creams and sunscreens as part of morning and evening routines
• Dermatologist-tested formulation aims for skin compatibility

How should I use Naturium Quadruple Hyaluronic Acid Serum in my routine?

Apply after cleansing and any light water-based treatments, then follow with a moisturizer to seal in hydration. Use morning and night, and always patch-test new products if you have reactive skin.

• Shake well, apply an even layer to face, neck, and chest
• Use twice daily for best results, then follow with moisturizer
• Suitable for combination, dry, sensitive, blemish-prone, and aging skin
• Patch test prior to full use; avoid mixing with incompatible active ingredients if directed by your clinician

Is this serum suitable for sensitive or acne-prone skin?

The fragrance-free, dermatologist-tested formula minimizes common irritants and is designed to be skin-compatible. Because it focuses on hydration rather than strong exfoliants or fragrances, many with sensitive or blemish-prone skin tolerate it well after a patch test.

• No synthetic fragrance, parabens, or gluten—reducing potential irritants
• Lightweight gel texture avoids heavy residue that can clog pores
• Can be incorporated into routines that target acne if used with guidance
• Patch test recommended for very reactive skin types

Who is this for: Naturium Quadruple Hyaluronic Acid Serum 5% is designed for anyone seeking a straightforward hydration booster—those with dry, combination, mature, sensitive, or blemish-prone skin who want a fragrance-free, dermatologically tested serum to layer under moisturizers and sunscreens. It’s suited to people who prefer clinically minded, ingredient-forward skincare without unnecessary additives and who want to add a targeted moisture step to their daily regimen.
