Givaudan has revealed efficacy insights into its hyaluronic acid portfolio, focusing on protection, repair and penetration for skin and hair fibres.
New data confirms the ability of its PrimalHyal Hydra[+] ingredient to effectively protect the hair fibre, even in rinse-off conditions.
The active ingredient has strong affinity with the hair surface, ensuring lasting benefits after rinsing.
These results translate into improved resistance of the hair fibre to external aggressions, particularly UV exposure, with visible smoothing of the cuticle, improved fibre integrity and enhanced mechanical properties such as elasticity and softness. In addition, the active ingredient helps repair hair damaged by thermal and mechanical aggressions, improving the overall quality of the fibre.
Other studies show that ResistHyal is specifically designed to address damaged hair. The active ingredient adapts its behaviour to the condition of the fibre, acting mainly on the surface of healthy hair while delivering deeper, targeted repair in compromised fibres.
This intelligent mode of action leaves hair smoother, stronger and easier to style, with a visible reduction in frizz and improved fibre cohesion, even after aggressive treatments.
On the skin, PrimalHyal Ultrafiller demonstrates long-lasting hydration benefits, with measurable improvements that persist up to 24 hours after a single application. The skin appears more hydrated, denser and more resilient, confirming its position as a reference HA for anti-ageing formulations.
Beyond hydration, new results highlight PrimalHyal Ultrafiller’s ability to support the structural integrity of the skin. Combined with complementary active ingredients, it helps limit the degradation of key extracellular matrix components under stressful conditions, reinforcing a holistic anti-ageing approach.
Finally, Spherulite HA Ultimate, developed on a 100% natural origin chassis in accordance with ISO 16128, confirms its ability to deliver active ingredients deeply and evenly within the skin. This optimised delivery system promotes consistent performance across the skin, opening up new possibilities for advanced HA-based formulations.
“Hyaluronic acid is often perceived as a single-function ingredient, but our work clearly shows that its performance depends on molecular design, delivery systems and biological context,” said Mathias Fleury, head of actives at Givaudan Active Beauty.
“By leveraging biotechnology and advanced characterization tools, we are setting new benchmarks for HA performance, not only in skin care but also in high-performance hair care,” he added.
