The La Roche-Posay Hyalu B5 Serum 30ml is a French dermocosmetic hydrating serum formulated with two molecular weights of pure hyaluronic acid, vitamin B5 and madecassoside to deeply hydrate, re-plump and soften the look of fine lines. Suitable for all skin types including sensitive skin, this lightweight anti-wrinkle serum absorbs quickly and leaves skin feeling bouncy, supple and comfortable, making it a trusted daily hydration step for dehydrated and mature skin.

Why This La Roche-Posay Serum Works

Dehydrated skin often looks tight, dull and creased, with fine lines becoming more visible by the middle of the day. This serum tackles that at the source by flooding the skin with moisture and helping it hold on to water. The result is skin that immediately feels plumper and more supple, with a fresh, healthy-looking radiance and a smoother surface under makeup.

Ideal For

This hydrating serum is ideal for dehydrated, mature or sensitive skin that needs a lightweight moisture boost without heaviness. It suits all skin types and layers well under makeup and SPF, making it well matched to the UAE's air-conditioned, warm climate where skin can lose moisture quickly. Those with a known fragrance sensitivity should patch test first, as the formula contains a light fragrance.

This anti-wrinkle formula pairs proven hydrating actives with soothing support for sensitive skin:

• Dual Hyaluronic Acid (0.3%): Larger molecules hydrate and plump the skin's surface while smaller molecules reach deeper to support volume and bounce.

• Vitamin B5 (Panthenol, 5%): A soothing, restoring ingredient that supports the skin barrier and keeps skin comfortable.

• Madecassoside (3%): Extracted from Centella Asiatica, it helps smooth the look of fine lines and boosts the plumping effect of hyaluronic acid.

• La Roche-Posay Thermal Spring Water: The brand's signature ingredient, valued for soothing sensitive skin.

For best results, apply the serum to clean skin morning and evening:

1. Cleanse and gently pat skin until slightly damp.

2. Apply three to four drops to the face and neck, massaging gently.

3. Follow with your moisturiser and, in the morning, sunscreen.

Applying to damp skin helps the serum absorb smoothly and reduces any tacky finish. It can be used alone or layered under other products.
