La Roche-Posay Hyalu B5 Hyaluronic Acid Serum - 30 ml, Vitamin B5 Hydrating Anti-Aging for Sensitive Skin

La Roche-Posay Hyalu B5 is a concentrated hyaluronic acid facial serum that plumps, hydrates, and helps restore the skin’s moisture barrier while remaining suitable for sensitive skin.

This serum combines a multi-weight hyaluronic acid system with vitamin B5, glycerin and soothing La Roche-Posay Thermal Spring Water to deliver immediate hydration and support skin recovery. The formula is allergy-tested and dermatologist-tested, designed to be used morning and evening either alone or layered under a moisturizer. The texture is rich yet absorbs to leave skin feeling bouncy and smooth without heavy residue.

How quickly will I notice improved hydration?

Most users report an immediate sensation of increased moisture and a softer skin feel after the first applications. Instrumental testing indicates barrier support is measurable within an hour, and repeated morning/evening use builds visible plumping and smoother texture over weeks.

• Apply 4–5 drops to face and neck morning and night for prompt hydration.
• Contains high and low molecular weight hyaluronic acids for multi-depth moisture.
• Glycerin and vitamin B5 help retain water and support barrier repair.

Will this serum help reduce fine lines and improve skin texture?

The concentrated hyaluronic system replenishes water in several skin layers, which can visibly soften the appearance of fine lines and refine texture as skin regains plumpness. Consistent use alongside your moisturizer enhances smoothing effects without aggressive actives.

• Targets dehydrated lines by restoring skin volume and bounce.
• Madecassoside-like soothing components support a calm, even surface.
• Clinically tested for improved texture when used twice daily.

Is Hyalu B5 safe for sensitive or reactive skin?

The formula is allergy-tested, dermatologist-tested and free from unnecessary fragrances that typically irritate sensitive skin. Thermal Spring Water in the blend adds calming minerals, while the gentle humectants focus on hydration rather than exfoliation or inflammation.

• Allergy-tested and developed under dermatological guidance.
• No harsh exfoliants or strong fragrances included.
• Suitable for daily use on reactive or easily irritated skin types.

How should I incorporate this serum into my skincare routine?

Use Hyalu B5 after cleansing and toning, applying 4–5 drops to damp skin to lock in moisture, then follow with your regular moisturizer or sunscreen in the morning. It can also be used as a hydrating booster layered under richer creams for extra barrier support.

• Morning: cleanse → serum → moisturizer → SPF.
• Evening: cleanse → serum → night cream or oil for sealing hydration.
• Can be mixed with your moisturizer for a hydration boost when needed.

Who is this for: La Roche-Posay Hyalu B5 is aimed at anyone seeking concentrated hydration and barrier support—especially those with dry, dehydrated, aging or sensitive skin who want a dermatologically driven serum to plump fine lines and restore softness. It fits into both minimalist and multi-step routines as a safe, effective hydrator to use daily.
