Neutrogena Hydro Boost Hyaluronic Acid Serum — 1 fl oz Lightweight Hydrating Serum, Fragrance-Free & Non-Comedogenic

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

This fast-penetrating serum was designed to replenish moisture in dry, thirsty skin without feeling heavy or greasy. Formulated to layer easily under moisturizers and makeup, it keeps skin feeling supple and comfortable while remaining non-comedogenic and hypoallergenic. Use 4–5 drops morning and night to improve surface hydration and help skin look smoother and more resilient.

How does this serum hydrate without leaving a sticky finish?

The formula combines low-molecular-weight purified hyaluronic acid with trehalose and glycerin so it binds water and carries it into upper skin layers. Because the ingredients are selected for lightweight performance, the serum absorbs rapidly, avoiding tackiness or heavy residue. That makes it ideal for morning routines and for layering under creams or sunscreen.

• Purified hyaluronic acid draws and holds moisture in skin’s surface layers.
• Trehalose and glycerin support sustained hydration and skin comfort.
• Fast-absorbing texture leaves skin prepped for moisturizer or makeup.
• Fragrance-free, minimizing sensory irritation and masking of active ingredients.

Can I use this on sensitive or acne-prone skin?

Yes—the serum is non-comedogenic and hypoallergenic, formulated to minimize pore-clogging and reduce the chance of irritation. Its gentle, fragrance-free makeup and lightweight base make it suitable for those prone to sensitivity or breakouts, when used as part of a balanced regimen.

• Non-comedogenic: formulated to avoid blocking pores.
• Hypoallergenic and fragrance-free for fewer irritants.
• Light texture reduces the likelihood of product buildup.
• Works well under acne treatments and SPF when applied first.

How do I add this serum into my daily skincare routine?

Apply on clean, dry skin after cleansing and any water-based toners or treatments. Dispense 4–5 drops, smooth over face and neck, then follow with your moisturizer and sunscreen in the morning or a richer night cream in the evening. The serum’s quick absorption helps the rest of your products layer more effectively.

• Step 1: Cleanse and pat skin dry.
• Step 2: Apply 4–5 drops to face and neck, gently pressing in.
• Step 3: Follow with moisturizer, then sunscreen during daytime.
• Tip: Use consistently AM and PM for best hydration maintenance.

Will this serum work under makeup and other treatments?

The lightweight consistency and fast-drying feel allow it to sit comfortably beneath makeup, sunscreens, and other topical treatments. Because it doesn’t leave a greasy film, foundations apply smoothly and remain stable throughout the day when you allow a minute for the serum to settle.

• Compatible with mineral and liquid foundations for even application.
• Pairs well with SPF—apply sunscreen after serum and moisturizer.
• Safe to combine with targeted actives when layered correctly.
• Does not interfere with makeup adherence or finish.

Who is this for: Neutrogena Hydro Boost Hyaluronic Acid Serum is suited to anyone seeking reliable, everyday hydration—especially those with dry, combination, or sensitive skin who want a non-greasy base for moisturizer and makeup. It’s also a practical choice for people new to hyaluronic acid who prefer fragrance-free, dermatologist-friendly formulations. If you need a simple, fast-absorbing boost of moisture for the face and neck that layers well and minimizes pore congestion, this serum fits smoothly into most skincare routines.
