InLei® Filler 3 – Step 3 Lash Filler Nourishing Serum (4ml)

InLei® Filler 3 is the final and essential step of the Lash Filler® treatment system, designed to deeply nourish, thicken, and regenerate natural lashes. Clinically proven to increase lash thickness by up to 24% over three treatments, Filler 3 uses a proprietary formula with micro-particles that penetrate the hair structure and bind to keratin fibers for visible strengthening and volume.

Formulated with InLei’s exclusive "Three Regeneration" complex, this serum enhances lash health at the root by stimulating keratinocyte activity in the hair bulb. Its precision dropper bottle ensures accurate application with zero waste, making it ideal for professional lash technicians.

Use Filler 3 after completing the Form 1 and Fix 2 steps, and following tinting, to unstick lashes from the shields and complete the treatment with softness, shine, and nourishment.
