Neutrogena Hydro Boost Hyaluronic Acid Serum for Face & Neck, 1 fl oz — Lightweight, Fragrance-Free Hydration

Neutrogena Hydro Boost Hyaluronic Acid Serum is a lightweight, fragrance-free daily serum that delivers deep hydration to the face and neck using purified hyaluronic acid, trehalose, and glycerin.

This fast-absorbing 1 fl oz serum is formulated to replenish skin’s moisture without feeling heavy or greasy. Designed for layering under moisturizers and makeup, it targets dryness and tightness by helping skin retain water for a plumper, smoother appearance. The fragrance-free, non-comedogenic formula is made to suit a wide range of skin types, including sensitive skin.

How does this serum hydrate without weighing skin down?

The serum uses purified hyaluronic acid — a humectant that attracts and holds water — combined with trehalose and glycerin to improve moisture retention. Because the formula is lightweight and fast-absorbing, it sinks in quickly and leaves no sticky residue, making it ideal for both morning and night routines.

• Purified hyaluronic acid draws moisture into surface layers.
• Trehalose helps stabilize and lock in hydration.
• Glycerin supports long-lasting suppleness and skin comfort.
• Quick absorption allows seamless layering with other products.

Will this serum work with sensitive or acne-prone skin?

This formula is fragrance-free, non-comedogenic, and hypoallergenic, which lowers the chance of irritation or pore-clogging for many users. Because it focuses on lightweight hydration rather than oils or heavy occlusives, it’s a suitable option for people with sensitive or acne-prone complexions when used as directed.

• Fragrance-free to reduce irritation potential.
• Non-comedogenic to help prevent pore congestion.
• Hypoallergenic formulation for gentle everyday use.
• Small, buildable doses avoid overloading the skin.

How should I add this serum into my skincare routine?

Apply 4–5 drops to clean skin on the face and neck in the morning and evening. Pat gently until absorbed, then follow with your regular moisturizer and sunscreen during the day; the serum is designed to layer under heavier products without pilling.

• Use on freshly cleansed skin for best absorption.
• Apply 4–5 drops and massage or pat into face and neck.
• Layer moisturizer and sunscreen over the serum in daytime.
• Consistent twice-daily use supports sustained hydration.

What results can I expect and how quickly?

Users often notice immediate smoothing and reduced tightness thanks to improved surface hydration. With regular application, skin can look and feel more supple and plump as the serum helps maintain the skin’s natural moisture balance over time.

• Immediate: smoother, less-dry surface feel after application.
• Ongoing: improved skin softness and more even texture with continued use.
• Compliments: works well under makeup without affecting finish.

Who this product is for: Neutrogena Hydro Boost Hyaluronic Acid Serum is intended for anyone seeking lightweight, reliable hydration for face and neck—especially those with dry, dehydrated, or sensitive skin who prefer fragrance-free, non-comedogenic products. It suits people who want a simple, effective serum to layer with moisturizers and sunscreens in both morning and evening routines.
