Neutrogena Hydro Boost Ultra Hydrating Serum — Fragrance-Free 1 fl. oz, Hyaluronic Acid Lightweight Hydration

A lightweight, fragrance-free serum that uses hyaluronic acid and Natural Moisturizing Factors to deliver long-lasting, non-greasy hydration for dry, sensitive, and acne-prone skin.

Neutrogena Hydro Boost Ultra Hydrating Serum comes in a recyclable glass bottle and is formulated to replenish skin without heavy oils or irritants. The formula pairs hyaluronic acid, which naturally attracts and retains water at the skin's surface, with amino acids and electrolytes to help restore moisture balance. Dermatologist-recommended and non-comedogenic, this serum is designed for daily use after cleansing and before moisturizer.

How quickly will I notice hydration and softer skin?

Visible improvement in moisture and texture appears rapidly: the serum provides an immediate boost to skin hydration and is clinically shown to sustain increased moisture levels for up to 72 hours after application. With consistent daily use, skin typically feels revitalized within two weeks and shows enhanced resilience after about a month.

• Instant delivery of lightweight hydration on application
• Clinically measured 72-hour hydration effect
• Noticeably softer, replenished feel after two weeks
• Improved skin resilience around four weeks

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

Yes — the Hydro Boost Ultra Hydrating Serum is formulated without fragrance, dyes, parabens, or phthalates and is non-comedogenic, meaning it is designed not to block pores. Its gentle, lightweight texture absorbs quickly without leaving a heavy residue, making it suitable for those who need hydration but are cautious about breakouts or irritation.

• Fragrance-free to reduce irritation risk
• Non-comedogenic, so it won’t clog pores
• Free of dyes, parabens, and phthalates
• Lightweight texture for comfortable daily use

What are the key ingredients and how do they work?

The serum centers on hyaluronic acid, a humectant that binds water to the skin’s surface to increase hydration levels. It also contains Natural Moisturizing Factors — a blend of amino acids and electrolytes — that help attract and retain moisture while supporting the skin’s natural barrier. Together these ingredients aim to hydrate, plump, and support overall skin comfort.

• Hyaluronic acid: binds and holds water at the skin surface
• Natural Moisturizing Factors: amino acids and electrolytes for moisture balance
• Weightless formulation that layers well under moisturizers and sunscreen
• Recyclable glass bottle for reduced plastic use

How should I add this serum to my daily routine?

Use the serum once or twice daily after cleansing and before applying moisturizer. Dispense a small amount and smooth evenly over face and neck until absorbed; follow with your regular moisturizer and sunscreen in the morning. Because it’s fragrance-free and non-comedogenic, it integrates easily into most skincare regimens.

• Apply after cleansing and toning, before moisturizer
• Suitable for morning and evening routines
• Works under makeup and sunscreen without pilling
• 1 fl. oz recyclable glass bottle for everyday use
