Hyalu B5 Suractivated Hyaluronic Acid Serum

While many hyaluronic acid serums provide hydration, not all are formulated the same. The Hyalu B5 Suractivated Hyaluronic Acid Serum is an advanced evolution of the original La Roche-Posay Hyalu B5 Serum, designed to deliver enhanced anti‑ageing performance.
This updated formula features breakthrough 4‑Dimensional Hyaluronic Acid Technology, combining four different forms of hyaluronic acid for superior penetration from upper to deep layers of the epidermis. High molecular weight hyaluronic acid helps support the skin moisture barrier, encapsulated average weight HA + Vitamin B5 to support skin renewal, low and micro‑weight HA for visibly plumper, smoother skin, plus a stimulating complex that boosts natural HA production. The result is improved anti-wrinkle efficacy and immediate tightening effects compared to standard formulations.

This hyaluronic acid serum delivers intense hydration while helping visibly improve the appearance of fine lines and wrinkles. Formulated with 4-dimensional hyaluronic acid, glycerin and vitamin B5, it attracts and locks in moisture to keep skin looking plump, smooth and refreshed. Suitable for all skin types, including sensitive skin.

Hyaluronic acid serums provide higher concentrations of this hydrating humectant than moisturisers and creams. The concentrated 4-dimensional hyaluronic acid technology in the Suractivated serum can penetrate multiple layers of the skin for deep hydration and enhanced results. This potent form of hyaluronic acid benefits the skin by:

• Drawing and locking in large amounts of water molecules for hydrated skin
• Visibly improving the appearance of fine lines and wrinkles
• Restoring natural hyaluronic acid levels that decline with age
• Helping to manage excess oil production, which can lead to breakouts
• Reducing visible redness
• Supporting the skin moisture barrier function
• Keeping the skin soft, plump and supple
• Providing immediate tightening effects and improved skin firmness

When choosing a hyaluronic acid serum, look for a formula that combines multiple molecular weights of hyaluronic acid to hydrate different layers of the skin. Advanced formulas go beyond surface hydration by helping lock in moisture, support the skin barrier and visibly plump skin.
The Hyalu B5 Suractivated Hyaluronic Acid Serum features innovative 4‑Dimensional Hyaluronic Acid Technology, combining high molecular weight hyaluronic acid for skin moisture barrier support, encapsulated average weight hyaluronic acid with 5% vitamin B5 to support skin renewal, and low and micro‑weight hyaluronic acid to visibly smooth fine lines. A stimulating complex helps support the skin’s natural hyaluronic acid levels for enhanced hydration and healthier‑looking skin over time.

Vitamin B5, also known as panthenol, is a key ingredient for maintaining hydration in the upper layers of the skin. In the Hyalu B5 Suractivated Serum, vitamin B5 is encapsulated with average weight hyaluronic acid to help support and comfort the skin.
In this high‑concentration serum format, vitamin B5 works as both a humectant and emollient. It helps draw and hold moisture in the skin, seal hydration between skin cells for long‑lasting comfort, and support the skin moisture barrier. Regular use helps skin feel softer, plumper and more resilient, while comforting skin that is prone to dryness or visible redness.

The Hyalu B5 Suractivated Hyaluronic Acid Serum should be used on clean, slightly damp skin, after cleansing and/or toning. Damp skin helps the product better absorb into the skin. Evenly apply 3-4 drops of the serum to your face and neck, gently massaging into the skin. You can use the Hyalu B5 Suractivated Hyaluronic Acid Serum twice daily, in your morning and evening routine. To enhance skin hydration, follow with Hyalu B5 Suractivated Hyaluronic Acid Cream. For your morning routine, finish with a broad-spectrum, high SPF sunscreen, like the Anthelios Invisible Facial Fluid Sunscreen SPF50+* to protect from UV damage.

ALWAYS READ THE LABEL AND FOLLOW THE DIRECTIONS FOR USE.

Apply 20 minutes before sun exposure. Sunscreen is only one part of sun protection so wear protective clothing and seek shade. Avoid prolonged sun exposure. Reapply every 2 hours before and after swimming, towelling and perspiring in accordance with directions.

Hyalu B5 Suractivated Serum is designed for the face and neck and should not be applied directly to the eye contour area. Instead, we recommend using our dedicated Hyalu B5 Hyaluronic Acid Eye Serum, specifically formulated to hydrate, re-plump and smooth the delicate under-eye area.

You can definitely use the Hyalu B5 Suractivated Hyaluronic Acid Serum with retinol! While retinol is excellent for promoting smoother skin through accelerated cell turnover, it can cause skin dryness. Adding a hydrating hyaluronic acid serum, like the Hyalu B5 Suractivated Serum, helps nourish and reinforce the skin by boosting hydration with its advanced 4-dimensional technology.

Because hyaluronic acid is a naturally occurring substance, the Hyalu B5 Suractivated Serum generally plays well with most other skincare products. Some ingredients may cancel out the hydrating effects of the Hyalu B5 Suractivated Serum, like stronger BHA/AHA serums, but these are generally a recommended pairing to maintain balance in the skin. If you have sensitive skin or oily skin prone to clogged pores, you might not want to layer on too many serums at once as it can overwhelm the skin. If you're using the Hyalu B5 Suractivated serum you also don't need to add other hydrating serums—you'll get plenty of hydration with just the one!

Hyaluronic acid serum typically lasts up to 12 months unopened. Once opened, store your serum in a cool, dry place away from direct sunlight and always close the bottle tightly after use to maintain formula stability.
