Naturium Quadruple Hyaluronic Acid Serum 5% Jumbo 2 oz — Deep Hydration & Plumping Fragrance-Free

Naturium Quadruple Hyaluronic Acid Serum 5% is a fragrance-free hydrating serum that combines four molecular weights of hyaluronic acid to deeply moisturize and visibly plump skin.

This 2 oz jumbo serum uses a layered approach to hydration: very low, low, medium and high molecular weight hyaluronic acid work together to attract and retain moisture at multiple levels of the skin. The gel-like texture absorbs quickly, creating a smooth canvas for moisturizers and makeup while supporting a more supple-looking complexion. The formula is pH-balanced (5.85–6.5), fragrance-free, vegan, cruelty-free, and designed for daily use on most skin types.

How does a quadruple hyaluronic acid blend benefit my skin routine?

Different molecular weights of hyaluronic acid act at varying depths, so combining them helps hydrate both surface layers and deeper skin layers. That multi-depth hydration improves skin elasticity appearance and reduces the look of dryness-related fine lines.

• Very low molecular weight penetrates deeper for longer-lasting moisture retention.
• Medium and low weights support mid-layer hydration and barrier function.
• High molecular weight forms a surface film to lock in hydration and smooth texture.

Will this serum work with my other skincare products?

Yes — the lightweight, gel-like serum layers well under moisturizers, oils, and sunscreen. Because it's pH-appropriate and fragrance-free, it’s compatible with most actives, though patch testing is recommended if you use strong exfoliants or prescription treatments.

• Apply on damp skin to maximize hyaluronic acid’s water-attracting properties.
• Follow with a moisturizer to seal hydration and reinforce the skin barrier.
• Safe to use morning and night as part of a regular routine.

How quickly will I notice results and what should I expect?

Immediate effects typically include smoother texture and a plumper appearance due to moisture uptake. With consistent daily use, you may see improved skin suppleness and reduced appearance of dryness-related lines as the barrier function is supported.

• Instant: skin feels hydrated and looks smoother after the first application.
• Short-term: repeated use over weeks enhances plumpness and comfort.
• Maintain results with regular application and proper moisturizing steps.

How should I apply this serum for best results?

Dispense a few drops and gently smooth the gel over face, neck, and chest after cleansing while skin is still slightly damp. Finish with your preferred moisturizer to lock in hydration and protect the lipid barrier.

• Shake well before use to ensure even texture.
• Use morning and night; follow with sunscreen in the AM.
• Patch test prior to full use, especially if you have sensitive skin.

Who is this for: Naturium Quadruple Hyaluronic Acid Serum 5% is aimed at anyone seeking reliable hydration and a plumper-looking complexion — including those with dry, combination, aging, or sensitive skin. It’s suitable for daily use by people who want a fragrance-free, pH-balanced serum that layers well with other treatments. If you prefer concentrated hydration in a larger size for extended use, the 2 oz jumbo bottle offers extra value without added scent or unnecessary additives.
