Can a revolution be revolutionised? For us at InLei®, the answer is not obvious. It requires time, energy, ambition and the courage to embark on a new adventure without any guarantee of success. But it is feasible!

What was our biggest fear?

Certainly not to match or exceed the excellent results we had already achieved. Projects like these require years of investment and resources. Not everyone has the courage to take such risks, especially if they already have an excellent line of high quality products.

THE BIG MOMENT IS COMING. We are making great progress and now, step by step, we want to take you on a journey through the innovations that are coming in 2024.

The idea 

The decision to renew our historic InLei® Lash Filler line came between 2019 and 2020. Working on production and keeping an eye on trends, we decided to improve our formulations to meet the growing market demand for "greener" and non-animal derived products.

The cosmetics world is constantly evolving and each innovation brings with it new challenges and opportunities. The transition to more sustainable ingredients, such as plant-based keratins, is a huge step forward. Like any big change, it requires extensive testing to ensure that product quality and efficacy are not compromised. Only time, research and practical application will determine whether these new ingredients can truly match or exceed the performance of traditional formulations. But with commitment and determination, the future looks promising. 

That's not all, we have seen a growing need in the lashmaker industry to speed up treatments, ensure clean results and minimise allergic reactions. A major commitment! So, we sat down with our trusted chemists and cosmetologists and began our adventure towards a new product line that would meet all these desires. 

Who would have thought that it would have taken us three times as long as the original line?

The development

In parallel with the development of a vegan formula, we optimised the formulations and the washing method for a green, fast and clean treatment. The objective was clear: to speed up and simplify the process without in any way compromising the quality of the end result, both in terms of curl and thickening of the lashes.

After testing different formulations and making numerous adjustments, we were ready. But not to launch the product. We were ready for another round of efficacy tests, to be carried out in a clinical laboratory. This was an essential step to ensure that the product really worked in terms of thickening eyelashes. Between October and December 2022, we conducted the tests at a renowned laboratory in Milan.

This time, the challenges were multiple:

  • Tests on different ethnicities and 37 models ( compared with the 20 in the tests carried out on the classic Lash Filler line), for a total of 110 treatments;
  • Measurement of not only the thickness but also the length of the lashes;
  • Comparative test to assess the effect of this upgraded InLei® Lash Filler treatment with and without the daily use of InLei® Adiutrix eyelash serum;
  • Introduction of an actual 'washing' of the lashes during the treatment, contrary to the conventional procedure.


The results

After three months of testing, we had to wait almost two months for the lab specialists to complete the processing of all the data and draw up the official report. The waiting was almost unbearable , also because the Christmas holidays that came between the end of the tests and the start of the data analysis definitely extended the time schedule. 

January 21st, 2023 was a memorable date: we received the official documents and announced to our entire staff and brand representatives that with the new formulations and the new working protocol, we had achieved some amazing results that confirmed our hard work!
