La Roche-Posay Hyalu B5 Serum & Retinol B3 Serum: Plump, Smooth, Renew—Hydrate Deeply, Refine Texture, and Boost Visible Firmness
Meet the La Roche-Posay Hyalu B5 Serum & Retinol B3 Serum—a purposeful two-step routine that pairs cushiony hydration with dermatologist-trusted renewal. Hyalu B5 Serum floods skin with multi-weight hyaluronic acid and soothing vitamin B5 for immediate plumpness and bounce. Pure Retinol B3 Serum brings line-smoothing, tone-evening power with stabilized retinol buffered by vitamin B3 and La Roche-Posay Thermal Spring Water for better comfort. Together, they create an easy cadence—hydrate → renew (SPF by day, essential)—that supports a fresher, smoother, more resilient-looking complexion.
Built around hyaluronic acid, retinol, and niacinamide (vitamin B3)—plus barrier-friendly humectants and the brand’s signature Thermal Spring Water—this duo suits normal, combination, and dry skin; sensitive-leaning users can enjoy it with sensible pacing.
La Roche-Posay Hyalu B5 Serum – 30ml
Instant cushion, lasting comfort.
A silky gel-serum that pairs two forms of hyaluronic acid (high and low molecular weight) with vitamin B5 to hydrate on multiple levels—softening fine dehydration lines and restoring a supple, elastic feel. The glide is plush yet fast-absorbing, making it a perfect base under retinol and makeup.
Key Ingredients:
- Hyaluronic Acid (multi-weight): Draws and holds water for immediate plumpness and smoother light reflection.
- Vitamin B5 (Panthenol): Soothes and supports barrier recovery.
- La Roche-Posay Thermal Spring Water: Calming, mineral-rich hydration.
Benefits:
- Instantly hydrates and visibly softens fine surface lines
- Cushions skin before actives (like retinol) to improve tolerance
- Leaves a dewy, comfortable finish without greasiness
Skin Type: All; especially dehydrated, tight-feeling, or dull.
How to Use:
Apply 2–4 drops to clean face/neck AM and/or PM. Press in; let it settle 30–60 seconds before next steps.
La Roche-Posay Pure Retinol B3 Serum – 30ml
Target lines, uneven tone, and texture—gently.
A high-performance serum that combines pure retinol with vitamin B3 (niacinamide) to visibly refine lines, smooth texture, and improve uniformity. The fluid texture spreads thinly, absorbing without tack, and is buffered to help reduce typical retinol dryness.
Key Ingredients:
- Pure Retinol (stabilized): Encourages surface renewal for smoother texture and fewer visible lines over time.
- Vitamin B3 (Niacinamide): Supports the barrier and helps even the look of tone.
- Thermal Spring Water + Humectants: Add comfort and glide for consistent use.
Benefits:
- Softens the look of fine lines and wrinkles
- Improves texture and tone clarity with steady use
- Balanced for performance with built-in soothing support
Skin Type: Most skin types; beginners and sensitive-leaning should ramp up gradually.
How to Use:
Use PM only on clean, dry skin. Start 2×/week, pea-size for face (half-pea for neck). Follow with a moisturizer. Increase frequency as tolerated. Always use SPF in the morning.
Why Choose the Hyalu B5 & Retinol B3 Duo?
- Two essentials—one goal: Hydrate deeply, then renew intelligently for smoother, bouncier-looking skin.
- Barrier-aware pairing: Hyalu B5 helps buffer and comfort skin so you can stick with retinol consistently—the secret to results.
- Makeup-friendly: Dewy hydration + refined texture = better base grip and less foundation settling.
- Simple rhythm: Minimal steps you’ll actually repeat—AM hydrate, PM hydrate + renew.
The Comprehensive Benefits of the Set
- Plumper look fast: Hyaluronic acid pulls in moisture for immediate cushion.
- Smoother over time: Retinol supports visible refinement of fine lines and uneven texture.
- More even-looking tone: Vitamin B5 + B3 calm and support, while retinol improves overall clarity.
- Comfort-first: Thermal Spring Water and humectants help maintain tolerance so progress doesn’t stall.
Best Practices: Your Simple Daily Routine
Morning (AM)
- Cleanse (gentle).
- Hydrate: Hyalu B5 Serum (2–4 drops).
- Moisturize as needed.
- Protect: Broad-spectrum SPF 30+ (non-negotiable when using retinol).
Evening (PM)
- Cleanse.
- Hydrate: Hyalu B5 Serum (thin layer; wait 60 sec).
- Renew: Retinol B3 Serum (pea-size; face; half-pea for neck).
- Moisturize (optional but recommended while ramping).
Pacing & Pairing Tips
Retinol ramp-up:
- Week 1–2: 1–2×/week
- Week 3–4: 2–3×/week
- Week 5+: Every other night (or as tolerated)
- Buffer for comfort: Sandwich method on frazzled days—Hyalu B5 → Retinol B3 → light moisturizer.
- With acids/Vitamin C: Use acids on a different night; keep vitamin C for AM, retinol for PM.
- Under-eye edges: Retinol can migrate—stay a fingertip away from lash lines; use the Hyalu B5 closer for hydration.
The Power of Ingredients — Why They Work
- Hyaluronic Acid (multi-weight): High-MW HA plumps at the surface; low-MW HA hydrates more deeply for bounce and smoother reflectivity.
- Retinol: A gold-standard derivative of vitamin A that normalizes the feel of surface renewal, improving visible lines, tone, and texture with patient, consistent use.
- Niacinamide (B3): Helps fortify the barrier, soften the look of redness, and promote a more uniform appearance—an ideal retinol companion.
- Vitamin B5 & Thermal Spring Water: Soothe and hydrate to keep tolerance high—critical for retinoid routines.
Troubleshooting & Pro Tips
- Dry or flaky? Reduce retinol to 1–2×/week, add an occlusive cream on top at night, and keep Hyalu B5 twice daily.
- Tingling/sting on application? Apply retinol over completely dry skin; buffer with Hyalu B5 + moisturizer.
- Pilling under makeup? Keep layers thin and allow 60 seconds between steps; press foundation instead of rubbing.
- Sun strategy: Retinol increases sun sensitivity—apply SPF 30+ every morning; reapply outdoors every 2–3 hours.
- Travel/climate shifts: In dry or cold conditions, use an extra pump of Hyalu B5; in humidity, keep moisturizer light.
Who Will Love This Set?
- Early lines & texture changes looking for visible refinement without heavy routines
- Dehydration-prone skin that needs bounce and cushion before actives
- Sensitive-leaning users who want retinol benefits with barrier support
- Minimalists & makeup wearers who value smooth prep and simple steps
Frequently Asked Quick Qs
Can I use Hyalu B5 and Retinol B3 on the same night?
Yes. Apply Hyalu B5 first, allow it to absorb, then apply Retinol B3, and finish with moisturizer if needed.
When will I see results?
Hydration is immediate. Texture and tone improvements from retinol typically appear over 4–8 weeks, with continued gains through 12+ weeks.
Can I use retinol every night?
Work up to it. Many land at every other night for long-term comfort and steady progress.
What if I already use acids or exfoliants?
Alternate nights with retinol to avoid over-exfoliation. Keep Hyalu B5 daily.
Is this suitable for acne-prone skin?
Often yes—retinol can help texture and post-blemish look; keep hydration steady and SPF strict.

The La Roche-Posay Hyalu B5 Serum & Retinol B3 Serum duo distills a derm-loved strategy into two steps you’ll actually keep: drench skin in HA-rich hydration, then refine with buffered retinol.
