La Roche-Posay Hyalu B5 Hyaluronic Acid Serum 30 ml — Vitamin B5, Deep Hydration & Plumping for Sensitive Skin

La Roche-Posay Hyalu B5 Serum is a concentrated hyaluronic-acid facial serum that intensely hydrates, helps restore the skin’s moisture barrier, and visibly plumps fine lines.

This advanced dermatological serum combines a multi-weight hyaluronic acid system with vitamin B5, glycerin, and La Roche-Posay Thermal Spring Water to deliver deep, long-lasting hydration. Formulated for sensitive skin and allergy-tested, the lightweight, non-greasy texture sinks in quickly and supports improved skin smoothness and elasticity. Clinical and consumer testing indicate rapid improvements in hydration, texture, and the appearance of fine lines when used morning and night.

How does this serum deliver deeper hydration than a regular moisturizer?

Hyalu B5 uses hyaluronic acids of different molecular sizes so water-binding molecules work at multiple skin depths. High-molecular-weight HA sits near the surface to smooth and plump immediately, while lower-weight fractions penetrate to hydrate deeper layers.

• 4-part hyaluronic acid system for multi-depth hydration
• Glycerin attracts and retains moisture throughout the day
• Vitamin B5 supports barrier repair to lock in hydration
• Non-oily serum texture that layers easily under creams or makeup

Will Hyalu B5 help reduce fine lines and visible aging signs?

The formula focuses on restoring moisture and elasticity, which can soften the appearance of fine lines and improve skin bounce. While it does not alter underlying skin biology like medical procedures, repeated hydration and barrier repair make lines look less pronounced and skin appear smoother.

• Hydration plumps superficial lines for a visibly smoother look
• Improved elasticity from repeated use enhances skin resilience
• Clinical and consumer testing shows faster surface recovery and better texture

How should I use the serum in my daily routine?

Apply 4–5 drops to cleansed face and neck twice daily, morning and evening, for best results. Gently press and smooth the serum into damp skin to maximize absorption, then follow with your moisturizer and sunscreen in the morning.

• Use after cleansing and any water-based treatments
• Pat into damp skin to lock in moisture
• Layer under cream or sunscreen; suitable for day and night use
• Safe for sensitive skin according to dermatologist and allergy tests

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

Yes — the formula is developed under strict dermatological standards and is allergy tested to suit sensitive skin. It is oil-free and non-comedogenic, which helps hydrate without adding pore-clogging oils, though individual reactions vary.

• Allergy-tested and recommended by dermatologists globally
• Oil-free texture reduces risk for congested skin
• Minimal fragrance and gentle supporting ingredients
• Patch-test first if you have known sensitivities

Who is this for: Hyalu B5 Serum is designed for anyone seeking targeted hydration and smoother-looking skin—ideal for people with dry, dehydrated, or mature skin that shows fine lines, and for those with sensitive skin who need a clinically tested, non-irritating serum. Use it as part of a daily anti-aging and hydration-focused routine to restore bounce and improve surface texture without heavy oils or sticky residues.
