Science
Mechanism of Action
This ingredient, also known as IDL (Isosorbide Di-(Linoleate/Oleate)), functions by stimulating prodifferentiation gene expression, thereby restoring and strengthening the epidermal barrier. It specifically upregulates genes critical for keratinocyte differentiation, such as KRT1, GRHL2, and SPRR4, and increases the abundance of key epidermal barrier proteins including filaggrin (FLG) and involucrin. Furthermore, it actively prevents cytokine-mediated degradation of the stratum corneum, downregulates unhealthy skin signature genes linked to epidermal homeostasis loss, and uniquely represses IFN-inducible coexpression modules. It also enhances the synthesis of essential lipids like ceramides, fatty acids, and cholesterol, contributing to robust antioxidant defense and overall skin health.

Key findings
- 01 A double-blind, placebo-controlled trial involving females with dry skin demonstrated that a 2% Isosorbide Di-(Linoleate/Oleate) lotion, derived from isosorbide esterified with sunflower fatty acids, significantly improved skin hydration and reduced transepidermal water loss (TEWL) after 2 weeks of application.
- 02 Beyond hydration and barrier function, HydraSynol™ IDL (Isosorbide Disunflowerseedate) is clinically proven to deliver significant improvements across multiple signs of aging skin.
