Naturium Quadruple Hyaluronic Acid Serum 5% Jumbo 2 oz — Fragrance-Free Hydrating, Plumping Face Serum

This 2 oz jumbo bottle delivers a concentrated 5% hyaluronic acid formula designed to attract and hold moisture at multiple skin depths. By combining very low, low, medium and high molecular weight hyaluronic acids, the serum aims to hydrate the surface, reinforce the lipid barrier, and support a smoother, fuller-looking complexion without added fragrance. The texture spreads easily into skin and plays well under moisturizers and makeup.

How does four-weight hyaluronic acid hydrate differently?

Each molecular weight targets a different layer of the skin: higher-weight molecules sit closer to the surface to lock in moisture, while lower-weight molecules penetrate further to support deeper hydration. The result is a more balanced and multi-layered moisturization strategy than using a single type of hyaluronic acid.

• High molecular weight: surface hydration and immediate plumping
• Medium weight: mid-layer moisture retention
• Low and very low weight: deeper hydration and improved skin feel
• Combined 5% concentration for noticeable hydration performance

Will this serum work with my existing routine?

Naturium’s gel-like serum is formulated to be routine-friendly: apply after cleansing and before heavier creams or oils. Its neutral pH (around 5.85–6.5) helps compatibility with most actives, though patch testing is recommended if you use strong exfoliants or retinoids.

• Layer under moisturizers, sunscreens, and makeup
• Safe to combine with most serums and treatments when used as directed
• Use morning and night for sustained hydration
• Patch test advised for sensitive or reactive skin

How will my skin look and feel after using it?

Regular application helps skin appear smoother and more supple by improving surface moisture and supporting the skin’s barrier. Texture feels lightweight and non-greasy, leaving a plump canvas that reduces the look of dryness-related fine lines.

• Immediate: smoother, dewy surface and easier makeup application
• Short term: reduced tightness and visible plumping
• Ongoing: improved moisture retention and skin comfort

Is this serum suitable for my skin type?

Formulated without fragrance and with a balanced pH, this serum is suitable for a wide range of skin types—dry, combination, oily, sensitive, and aging skin can all benefit from layered hydration. Those with active skin conditions should consult a dermatologist before adding new actives.

• Good for dry, dehydrated, and combination skin
• Appropriate for sensitive skin due to fragrance-free formula
• Works for oily skin when used sparingly because of lightweight gel texture
• Not a replacement for medical treatments—consult a professional if needed
