Description
La Roche-Posay Hyalu B5 Hyaluronic Acid Serum 30ml — Pure Hydration & Skin Repair
The La Roche-Posay Hyalu B5 Hyaluronic Acid Serum (30ml) is the brand's dedicated hydration and barrier repair serum — formulated without any exfoliant for daily intensive moisturisation. Using two molecular weights of hyaluronic acid for multi-depth hydration, vitamin B5 (panthenol) for barrier strengthening, and madecassoside for collagen support, it visibly plumps and firms dehydrated skin from the first application.
Key Ingredients
- Hyaluronic Acid (Two Molecular Weights): Large HA molecules attract and hold moisture at the skin's surface; smaller hydrolysed HA molecules penetrate deeper layers for sustained hydration and plumping.
- Vitamin B5 (Panthenol): Repairs and strengthens the skin's natural moisture barrier, reducing transepidermal water loss.
- Madecassoside: A centella asiatica derivative that accelerates collagen synthesis, improving skin firmness and elasticity over time.
- La Roche-Posay Thermal Spring Water: Provides baseline soothing and antioxidant benefit throughout the formula.
Not an Exfoliating Serum
This serum contains no glycolic acid, AHA, or BHA. It is a pure hydration and repair formula — complementary to (not the same as) the La Roche-Posay B5 Glycolic Acid Serum. Both are available at Derma.pk if you need both hydration and resurfacing in your routine.

Usage & Benefits
- Multi-Level Hyaluronic Acid Hydration: Two molecular weights of HA — large molecules plump the skin surface while smaller molecules penetrate deeper for lasting moisture.
- Skin Barrier Repair (Vitamin B5): Panthenol strengthens the skin's protective barrier, reducing water loss and improving resilience.
- Firming & Collagen Support (Madecassoside): Accelerates natural collagen synthesis to restore skin elasticity and firmness over time.
- Plumps Fine Lines: Visibly reduces the appearance of dehydration lines and early wrinkles through intense hydration.
- No Exfoliant — Pure Repair: Contains no AHA or BHA — safe for daily use alongside other actives without increasing sensitivity.
- Hypoallergenic & Paraben-Free: Minimalist formula without parabens or colorants — tested and recommended by dermatologists for sensitive skin.
How To Use

3. Gently press and massage the serum into skin using upward motions until fully absorbed.
4. Follow with your preferred moisturizer to lock in the hydration from the serum.
