Science
Mechanism of Action
This extract functions by actively preventing the degradation of Fibroblast Growth Factor-2 (FGF-2), thereby ensuring its sustained bioavailability for skin fibroblasts. It mimics the protective role of heparan sulfate proteoglycans and concurrently stimulates the synthesis of sulfated Glycosaminoglycans (GAGs), offering a dual mechanism for improved skin biomechanical properties and visible wrinkle reduction. Rich in bioactive compounds such as essential fatty acids, flavonoids, phytosterols, polyphenols, and Vitamin C, it provides comprehensive nourishing, antioxidant, and anti-inflammatory benefits, promoting collagen production, cell regeneration, barrier strengthening, and mitigating hyperpigmentation and redness. Additionally, it exhibits astringent and antiseptic properties.

Key findings
- 01 A cosmetic active ingredient containing Hibiscus Abelmoschus Seed Extract (Linefactor™) was clinically confirmed to enhance skin biomechanical properties and reduce the appearance of wrinkles.
- 02 Evaluations demonstrated that the extract dose-dependently protected Fibroblast Growth Factor-2 (FGF-2) from thermal degradation, supporting its mechanistic claims.
- 03 Lotions (o/w) containing 1-7% w/w of a related extract (Abelmoschus esculentus L. seed extract) were physically and chemically stable over six heating/cooling cycles, indicating potential for anti-aging and whitening effects, though specific effective concentrations were not detailed.

Stability
The extract's intrinsic pH is generally neutral to slightly acidic. Formulations containing Hibiscus abelmoschus oil extract, specifically creams, have shown stability within a pH range of 7.4-7.9. Furthermore, lotions containing 1-7% w/w of a closely related Abelmoschus esculentus L. seed extract maintained physical and chemical stability through six heating and cooling cycles.
Safety
Safety Profile
Generally recognized as safe for cosmetic applications when used as directed. However, individuals with known allergies to plants in the Malvaceae family or those with sensitive skin should exercise caution. Direct contact with eyes and mucous membranes should be avoided. While the FDA lists 'Ambrette Seed, Oil (Hibiscus Abelmoschus L.)' as GRAS for flavoring, a specific CIR review for cosmetic use is not available, nor are specific SCCS opinions regarding restrictions listed in the CosIng database.
