Neutrogena Hydro Boost Ultra Hydrating Serum — Fragrance-Free 1 fl oz, Lightweight Hyaluronic Acid for 72-Hour Hydration

Neutrogena Hydro Boost Ultra Hydrating Serum is a lightweight, fragrance-free hyaluronic acid serum that delivers long-lasting hydration and helps restore skin's moisture balance.

This lightweight facial serum comes in a recyclable 1 fl oz glass bottle and is formulated to replenish dry, sensitive, and acne-prone skin without adding weight or clogging pores. It combines concentrated hyaluronic acid with Natural Moisturizing Factors—such as amino acids and electrolytes—to attract and retain water at the skin’s surface. The result is a visibly softer, smoother complexion when incorporated into a daily routine.

How quickly will I notice hydration after using this serum?

Many users experience an immediate sensation of increased moisture and improved skin texture right after application. Clinically, the formula provides prolonged hydration that supports skin feel for up to 72 hours, with continued improvement over weeks of consistent use.

• Instant burst of moisture on contact
• Clinically measured hydration lasting up to 72 hours
• Visible softening and smoothing with regular use

What ingredients deliver the hydrating benefits?

The serum centers on hyaluronic acid, a molecule naturally found in skin that binds to water to plump and hydrate. It also contains Natural Moisturizing Factors—like amino acids and electrolytes—to help attract moisture and support the skin’s barrier.

• Hyaluronic acid binds and retains water for immediate plumping
• Natural Moisturizing Factors help draw and hold moisture
• Formulated without fragrances, dyes, parabens, or phthalates

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

The formula is designed to be gentle and non-comedogenic, so it hydrates without blocking pores or adding irritants. Its fragrance-free and dye-free profile reduces the risk of irritation, making it appropriate for many people with sensitive or blemish-prone skin.

• Non-comedogenic to avoid pore congestion
• Free of fragrance and dyes to minimize potential irritation
• Suitable for dry, sensitive, and acne-prone skin types

How should I add this serum to my daily skincare routine?

Use the serum after cleansing and before your moisturizer to lock in hydration. Apply evenly to the face and neck once daily; follow with a moisturizer and, in the morning, sunscreen for daytime protection.

• Apply to clean face and neck daily after cleansing
• Follow with moisturizer and sunscreen for daytime use
• Consistent use shows improved resilience after several weeks
