InLei Filler 3 Bottle
The InLei Filler 3 Bottle provides the nourishing third stage of the professional Lash Filler 25.9 treatment. Applied after the lifting, setting and optional tinting stages, the vegan formula helps condition, reinforce and replenish the natural lash structure.
The treatment combines vegetable keratin, amino acids, glycerine and targeted conditioning ingredients. It supports improved moisture, strength, flexibility, thickness and shine while preparing the lashes for the final Lash Molecular 4 reconstruction stage.
Professional Lash Filler Step 3
InLei Form 1 first prepares the natural lashes for reshaping, while Fix 2 stabilises their new curvature. Filler 3 then conditions the treated hairs and helps restore moisture following the preceding chemical stages.
This professional lash filler is designed to support the connection between the cuticle and internal hair structure. It leaves the lashes feeling softer and more flexible while helping protect them against dryness and breakage.

Lash Filler 25.9 Treatment Results

When the salon treatment was combined with daily use of InLei Adiutrix serum for three months, tested results reached up to 28% thickening and 12% lengthening. Individual outcomes can vary according to the client’s natural lashes, treatment consistency and aftercare.
