No7 HydraLuminous+ Hydrating Facial Serum 2% Hyaluronic Acid, 5% Niacinamide — 1 fl oz, Lightweight Long-Lasting Hydration

No7 HydraLuminous+ 2% Hyaluronic Acid Serum is a concentrated hydrating facial serum formulated with multi-weight hyaluronic acid and 5% niacinamide to help boost moisture levels and support the skin barrier.

This lightweight serum combines targeted hydration technology and barrier-supporting ingredients to visibly refresh and plump the skin. Designed for daily morning and evening use, the formula blends sodium hyaluronate in three molecular sizes to deliver moisture across different skin layers while niacinamide helps reduce moisture loss and strengthen the skin’s natural defenses. The product also incorporates Pollution Shield Technology to help the skin appear more radiant despite environmental stressors.

How does this serum hydrate skin for hours?

The serum uses a 3-in-1 hydration approach: three molecular weights of hyaluronic acid that attract and retain moisture at multiple depths. In an instrumental hydration test, it delivered prolonged hydration compared with a leading No1 serum, and the formula is proven to lock in moisture for up to 96 hours under test conditions.

• 2% concentrated hyaluronic acid (as sodium hyaluronate)
• Three molecular weights to reach surface and deeper layers
• Clinically measured extended hydration up to 96 hours

What role does 5% niacinamide play in this serum?

Niacinamide at a 5% concentration supports the skin’s barrier and helps reduce water loss, so hydrated skin holds moisture better over time. It also contributes to an overall healthier-looking complexion without adding heavy texture, making it compatible with most skincare routines.

• 5% vitamin B3 (niacinamide) to support barrier function
• Helps maintain hydration by reducing trans-epidermal water loss
• Lightweight texture layers well under moisturizers and SPF

Will this serum help protect against environmental stressors?

The formula includes Pollution Shield Technology, which helps the skin appear more radiant when exposed to everyday pollutants. While not a substitute for physical protections, this technology is intended to reduce the visible effects of environmental stress and support skin clarity.

• Pollution Shield Technology to help defend against airborne particles
• Non-greasy finish suitable for daily layering
• Can be combined with serums, moisturizers, and sunscreen

How should I use the HydraLuminous+ serum for best results?

Apply the serum to clean, dry skin twice daily—morning and night—or add 2–4 drops into your moisturizer. For optimal results, incorporate it into the full HydraLuminous+ routine and follow with sunscreen in the morning to protect your skin.

• Use after cleansing and before moisturizer, morning and evening
• Mix 2–4 drops into cream for added hydration boost
• Layer under SPF during daytime routine

Who is this for: No7 HydraLuminous+ 2% Hyaluronic Acid Serum suits anyone seeking an accessible, science-backed hydrating booster—especially those with dehydrated, dull, or moisture-compromised skin. It’s formulated to fit into most routines, including those who use active ingredients, and is a good choice for people who want a lightweight serum that enhances hydration, supports barrier function, and helps maintain skin radiance amid urban environments.
