This serum was developed in response to the growing demand for scientifically credible anti-ageing solutions in the premium naturals space. The brief required a product that delivered measurable results while meeting COSMOS certification criteria — without the stability challenges associated with conventional retinol.

The solution uses microencapsulated retinol to overcome oxidative instability, combined with Gatuline® Skin-Repair — a 100% natural beech bud bioactive with its own in-vivo data. The two actives work on complementary pathways, with the hyaluronic acid and Aquaxyl™ providing immediate and sustained hydration as supporting benefits.

Carbopol® Ultrez 21 was selected as the primary rheology modifier for its excellent clarity and compatibility with actives at this pH range. The formula remains clear and stable across 12 months at 25°C and 6 months at 40°C accelerated testing.
