Form1:
Permanent composition for eyelashes and eyebrows, specially designed for perfect interaction with the Lash Filler line. All ingredients are of Italian origin. Optimal pH (9.73) ensures fast yet gentle penetration into the hair, preparing it for Fix 2
Use only in tandem with IN LEI® “FIX2”
Fix 2:
Fixing composition for eyelashes and eyebrows from the Lash Filler line. Based on hydrogen peroxide. The formula is perfectly balanced, ensuring stable performance and ideal interaction with Form1 and Filler3. Guarantees a stable, long-lasting curl
Filler 3:
Unique product with no analogues, fully developed and tested in Italy. Proven by the Milan Research Institute to thicken eyelashes up to 24% in three procedures. Formula allows microparticles to delicately penetrate the hair fiber. BIOTINOL TRIPEPTIDE-1 binds to keratin thanks to the chemical curling process, ensuring long-term results (only effective with IN LEI® “FORM 1” and “FIX 2”). Filler nourishes and strengthens the hair root, prolonging effects for months. Can also be used as an oil for lashes and brows — daily for 1–2 months with massage
Lash Molecular 4:
The final step of Lash Filler 25.9, balancing the hair structure and enhancing shine, strength, elasticity, flexibility and color durability. Active ingredients: Hydroxypropyltrimonium Hyaluronate (advanced hyaluronic acid for hydration), Quinoa protein (improves hair structure and shine), Hydrolyzed wheat proteins (protective barrier and hydration), Hydrolyzed vegetable protein (protects against mechanical and chemical damage). Apply with InLei® F-Brush until fully absorbed, no rinsing needed
