The lash industry has often reduced complex science to surface-level explanations —
approaching lash systems as simple adhesive events rather than interconnected material
ecosystems.

In reality, lash extensions are highly detailed micro-ecosystems of interacting surfaces and
interfaces. They involve reactive monomers, engineered polymers, living keratin fibers, eyelid
skin, and continuous ocular exposure — and we’ve only begun to explore their scientific depth.
In this advanced webinar, Lash Science Specialist Dianna reframes lash extensions through
the lens of surface science and interfacial chemistry.

Together, we will examine the complete interface network:

Adhesive ↔ Air
Adhesive ↔ Glue Holder
Adhesive ↔ Synthetic Lash
Adhesive ↔ Natural Lash
Lash System ↔ Eyelid Skin
Lash System ↔ Ocular Environment

You’ll gain insight into wetting behavior and surface energy, bead geometry and penetration,
polymerization dynamics and exposure pathways, and mechanical fatigue and durability — and
how these factors influence performance, efficiency, and safety.

This session is designed for lash professionals, educators, and brand leaders ready to
understand lash systems at a deeper scientific level and rethink products as cohesive,
engineered surface ecosystems.

Because when you understand the interfaces, you don’t troubleshoot symptoms — you design
better systems.
