A high-end skincare brand in the Middle East, while developing an anti-aging firming cream, aimed to achieve a comprehensive effect of "instant hydration + long-lasting firming + anti-aging repair." However, in the initial formulation, the client encountered the following problems: single-molecule hyaluronic acid only provided basic hydration, lacking firming effect; simultaneously, the absorption efficiency of anti-aging active ingredients was not ideal, resulting in an overall product lacking depth and failing to meet the demands of the high-end market.

To address this issue, we recommend using a multi-molecular weight compound system of Sodium Hyaluronate, which achieves layered action through different molecular weights:

• 10 kDa (low molecular weight): Enhances permeability and assists anti-aging active ingredients in their effectiveness.
• 800 kDa (medium molecular weight): Improves skin hydration and elasticity.
• 1600 kDa (high molecular weight): Forms a moisture-locking film on the skin surface, providing an immediate feeling of firmness.

The final product performed well in testing: Skin felt smoother and firmer immediately after use, with a significantly improved absorption rate compared to before optimization; after two weeks of continuous use, skin elasticity and fine lines were improved. Customer feedback indicated a premium feel and longer-lasting hydration, and the product successfully entered high-end skincare channels in the Middle East.
