High-Molecular-Weight Keratin for Biologically Active Dermocosmetic Systems
Kerline HMW keratin is a non-hydrolyzed, high-molecular-weight structural protein engineered for advanced dermocosmetic formulations targeting skin integrity, regeneration, and protection.
Supplied as a ready-to-formulate aqueous solution (1–4%), it enables multifunctional performance in skin care systems.
In vitro studies on human keratinocytes (HaCaT) demonstrate:
• Sustained cell proliferation comparable to positive control • Maintenance of Collagen I expression • Modulation of α-SMA expression • Significant reduction of CK18 (marker associated with cellular stress)
These results indicate support of regenerative and homeostatic pathways at cellular level.
Anti-Inflammatory Modulation
In reconstructed skin models and cellular assays, HMW keratin formulations demonstrated:
• Reduction of IL-6 and IL-8 expression • Improved cellular viability (MTT assay) • Excellent biocompatibility
This profile suggests potential use in:
• Post-procedure soothing systems • Barrier-supporting dermocosmetics • Sensitive skin formulations • Anti-age structural support systems
(Data derived from internal studies and university collaborations.)
Film-Forming Protective System
HMW keratin forms continuous biomimetic protein films on skin surface.
Functional implications:
• Protective film formation • Moisture retention support • Structural reinforcement of stratum corneum surface • Compatibility with active delivery systems
Unlike synthetic film-formers, keratin is biodegradable and derived from upcycled wool.
Validated in Real Formulations
HMW keratin has been incorporated into:
• Regenerative serum systems • Lenitive dermocosmetic creams
