InLei® Lash Filler Combo (STEP 1,2,3,4) Bottle or Sachets

InLei® Lash Filler 25.9 is a four-step professional lash lift and volumising system that lifts, thickens, and strengthens the natural lashes. It enhances lash curl while clinically increasing lash thickness by up to 25% over multiple treatments — delivering long-term results with zero damage when performed correctly

Unlike traditional lash lifts, InLei® Lash Filler 25.9 is a scientifically developed, clinically tested system that not only lifts the lashes but reconstructs and nourishes them from within. It’s the only system on the market with proven thickening results, making it a superior treatment for professionals who care about lash health and growth, not just appearance.

Technically, yes—but you’ll only achieve the lifting and setting results, without the long-term volumising, repairing, and anti-breakage benefits that come from Step 4.

For the full Lash Filler 25.9 effect, all four steps must be used as a complete system. Omitting Step 4 means your clients won’t see the progressive increase in lash thickness or strength that sets this system apart.

Step 1 – FORM 1: Softens the internal lash structure to allow safe reshaping

Step 2 – FIX 2: Locks in the new curl and restores lash bonds

Step 3 – FILLER 3: Deeply penetrates the hair structure to nourish, strengthen, and thicken lashes

Cleansing Step – InLei® Magic Mousse: Gently cleans the lashes after Filler application, removing residue and preparing the lashes for the final step without compromising the results.

Step 4 – MOLECULAR 4: A cutting-edge final step that repairs, reinforces, and seals the results — protecting against breakage, dehydration, and over-processing

This 4-step synergy delivers lift, volume, health, and structure, making it a true filler system, not just a lash lift.

Only when all steps are used in sequence — including the cleansing mousse — will clients receive the full volumising, curling, and protective results that define Lash Filler 25.9.

For best results, we recommend a course of 3 treatments spaced 4–6 weeks apart. This allows the nourishing effects of Steps 3 and 4 to build progressively, enhancing natural lash density, length, and strength over time.

Yes—in trained hands, the InLei® Lash Filler 25.9 system is suitable for most lash types, including fine, short, or damaged lashes.

It’s also formulated without harsh ingredients, making it ideal for clients with sensitive eyes, though a patch test 24–48 hours before treatment is strongly recommended.
