InLei® Filler 3 is the last step and the "Magic Potion" in the Lash Filler treatment. This is where all the nourishment and thickening are created.

LASH FILLER® TREATMENT is structured starting from a winning formula of very delicate perm which is the basis of the whole process. It continues with the tinting which is specially designed to be in tandem with the chemical process and combined with refined oxygen of 1.5% (Developer). Finally, it closes and seals the process, the Filler that defines, nourishes, thickens and strengthens the structure of the lashes, giving colour and shine to our client's lashes.

This revolutionary product has been entirely structured, tested and produced in Italy. The LASH FILLER® treatment guarantees an average thickening of the natural hair by up to 24% in three treatments. It has been demonstrated and affirmed by the clinical test carried out at the Research Institute of Milan.

The original formula of In Lei® “FILLER 3” allows the microparticles of the filler to penetrate into the hair delicately, binding to the keratin fibres of the hair itself. Thanks to the “Three Regeneration” complex, and to the adequate preparation of the lashes with In Lei® “FORM 1” and In Lei® “FIX 2”, it guarantees a stable result and highly effective nourishment and thickening, giving new silkiness to the lashes. The LASH FILLER® treatment can reach the hair bulb, nourish them and work on the hair bulb's structure in the following months after the treatment. 

Furthermore, In Lei® "FILLER 3" favours the proliferation of keratinocytes inside the hair.

The packaging also gives charm to the product and guarantees its use without unnecessary waste. Thanks to the convenient dropper, we are able to withdraw the necessary quantity from the vial without contaminating the product.

How to use:

  1. It is used after the InLei® Form 1, Fix 2 and the tinting process.
  2. Remove a few drops of Filler 3 from the bottle with the dropper and deposit it in a solo dish.
  3. With the help of the InLei® Picasso brush and with quick movements, the product is rubbed onto the natural lashes and the follicle.
  4. Allow the product to penetrate until completely absorbed.
  5. It does not get rinsed off.

For professional use only
