Neutrogena Hydro Boost Hyaluronic Acid Serum

Hyaluronic Acid (Sodium Hyaluronate) (strength not specified), humectants (e.g., glycerin) and water-based serum base (exact full INCI varies by pack/market)

Hydration and moisturisation of facial skin, helps relieve dryness and tightness, supports skin barrier and improves plumpness/smooth appearance

Hyaluronic acid is a humectant that attracts and binds water in the stratum corneum to improve skin hydration. By increasing water content of the outer skin layers, it temporarily plumps skin and reduces the appearance of fine dehydration lines.

For external use only. Apply 2–3 drops to clean, slightly damp face and neck once or twice daily; follow with a moisturiser. Use sunscreen in the daytime. Avoid contact with eyes and broken/irritated skin.

Mild stinging, redness, irritation, itching, dryness, rash, acne/comedones (in some), allergic reaction (rare)

Patch test before first use. Stop use and consult a doctor if severe irritation, swelling, blistering or rash occurs. Avoid eye area; rinse well with water if contact occurs. Do not apply on cuts, sunburned or severely irritated skin. If you have very sensitive skin or eczema/rosacea, use with caution.

No clinically significant drug interactions expected for topical cosmetic hyaluronic acid. If layering with strong actives (retinoids, AHAs/BHAs, benzoyl peroxide), irritation may increase—introduce gradually and monitor.

Store at room temperature (below 25–30°C), away from direct sunlight and heat. Keep cap tightly closed; do not freeze; keep away from children.
