From a simple eyelash perm to a truly professional treatment: here's the "Lash Filler"

I would like to introduce you to a brand new product that is not yet available for sale but which is already well-known and highly anticipated.

I'd like to tell you about a completely new product that recently hit the market, but which was already generating great anticipation and interest before its launch.

Before going into the details, however, I want to briefly share my personal experience with the evolution of eyelash treatments.

I still remember 15 years ago, when I visited a beauty salon in Ukraine—my home country—the first in my city to offer eyelash perms . It was an innovative treatment designed to enhance the natural curl of the lashes. However, since I have very blonde and thin lashes, as is often the case in my area, I didn't notice a particularly noticeable change. I've lived in Italy for 12 years, and eyelash perms have only begun to gain popularity here in the past five or six years. I was surprised to discover that Italy—the home of beauty, trends, and hairstyles (and therefore hair products)—was so far behind in eyelash innovation. I was already using eyelash extensions back then, and at the same time, I began studying how perms worked. I discovered that the new formulations were much more effective than the initial ones, and incorporating them into my client offerings was a completely natural progression.

Meanwhile, the sector has continued to evolve. Today we can benefit from a wide range of treatments: from eyelash lamination to botox, up to the numerous products to stimulate its growth . Let's see together what the fundamental differences are between these treatments:

Permanent	Lamination	Botox	Growth product
1. Based on ammonia and hydrogen peroxide. 2. It opens the hair scales allowing substances to penetrate inside. 3. Gives a stable curvature without any significant nourishment.	1. Based on thioglycolic acid and sodium bromate. 2. Gently penetrates the hair without opening the scales. 3. It provides stable curl by nourishing the hair internally. With proper maintenance, the nutrients remain inside the hair and cannot be washed away.	1. It is used in addition to the perm treatment in lamination or alone. 2. Exclusively nourishing substance for natural hair based on keratin, panthenol, and argan oil. Nourishes the cortex of the eyelashes.	1. Made with a wide variety of ingredients: it depends on the brand, the nourishment, and the hair strengthening effect. Some are even hormone-based. 2. It penetrates the hair, some reaching the bulb, stimulating eyelash growth. 3. The hair actually grows in length but not in density, therefore remaining fragile and “empty”.

In recent years, I've become fascinated with the chemical side of the treatment, delving into its composition, mechanism, and applicability. When I wrote this article, the product wasn't yet available, but today I can finally reveal the big secret: it's officially here ! And you, readers of the "lashINbrow Blog," can discover all the details here.

After a long journey and countless tests, the formulas were confirmed , approved, and ready for the market. But we didn't stop there! Thanks to InLei®, we have created a complete line of professional products that transform lashes into a true masterpiece of beauty, combining innovation, effectiveness, and deep care.

Eyelash Perming vs. Lash Filler: The Revolution in Treatment

For years, I worked with eyelash perms, which were the most common solution for achieving a more open and vibrant look. But deep down, I knew it wasn't enough . Perms changed the look, sure, but they didn't care for or nourish the lashes. In fact, over time, they could even weaken them. So, as I mentioned before, I started asking myself questions, studying, and experimenting. That's how Lash Filler was born: my project, my vision, my little revolution.

I wanted to create a treatment that was not only beautiful to look at, but also healthy to experience . A treatment that didn't just curl, but also deeply regenerated, thickened, and strengthened lashes. And I succeeded! With Lash Filler, lashes not only look more beautiful, they actually become stronger: in just 3 treatments , an average increase in thickness of 24% can be achieved. I developed 8 different types of curlers to offer a personalized curl , suitable for every eye type and structure. And above all, I formulated an active complex that nourishes , stimulates growth, and respects the hair, without compromising its integrity.

Since July 2017, Lash Filler has entered professional salons, and the results have also been confirmed by clinical tests at the Milan Research Institute .

It was a challenge, a long and exciting journey, but today I can proudly say: I created the first treatment that combines aesthetics and eyelash health in a single step . If you too are tired of treatments that stop at the surface, then you are ready to discover what can truly enhance your eyes. Come and discover the revolutionary world of  Lash Filler and let yourself be won over by the solutions that are changing the way eyelash treatments are performed!

The birth of a perfectly curved dream: curlers

Every innovation stems from an intuition, but it's passion that turns it into reality. What I'm about to tell you is the story of how a seemingly simple idea sparked a small revolution in the world of eyelash treatments . A journey of research, collaboration, and sheer determination, which led to the creation of a one-of-a-kind curler.

It all started with the desire to create a set of curlers that could truly adapt to all eye shapes and lash types . It seems like a simple idea, but it has taken me much further: I have developed innovative formulas that offer never-before-seen results, all clinically tested and scientifically confirmed.

I fell in love with this treatment thanks to someone I owe so much to: Maria Ravinskaiya . I can't help but mention her, because without her, none of this would have been possible. For those who don't know her, Maria is the leading expert in eyelash lamination and perming in Russia and Europe. I'm convinced that at least 60% of the teachers of this treatment currently on the market have been fortunate enough to have received her training. I remember the nights spent on the phone working together to find the perfect formula for the curler .

Months of technical drawings, studies, discussions, and experiments followed to arrive at the ideal mold and, above all, the perfect silicone, giving life to a curler entirely Made in Italy, of the highest quality and with real, tangible benefits for every professional.

Our efforts have paid off: we have managed to create a perfect shape and a set of zero-waste curlers , where each piece is truly usable and reusable. Designed to adapt to a wide range of eye shapes and all lash lengths, these new Made in Italy curlers , by InLei® , are ideal even for the most sensitive people. Choose our eyelash curlers and discover a new approach to lamination: a real step forward in professional eye treatments.

Behind the Perfect Lashes: The Heart and Chemistry of Lash Filler

Alongside the development of our line of curlers, we also created the formulas for the new "Lash Filler" treatment. This is the result of constant and passionate research , carried out by my husband and I. It is a project born from our shared vision, enriched by the expertise of the best Italian chemists and the invaluable experience of the Russian Master , with whom we have actively collaborated. I firmly believe that this treatment represents a true revolution for lash makers and eyelash stylists, bringing innovation and quality to the sector.

The Lash Filler treatment is based on a gentle perming formula , designed to be the ideal foundation for the entire process. We developed a specific eyelash dye perfectly compatible with the chemical reaction, to be used in synergy with a refined and calibrated 1.5% oxygen. Completing the treatment is the heart of the system: the Filler, which closes and seals the cycle, nourishing, thickening, and strengthening the lash structure . The result? More defined, shiny, colorful, and visibly healthy-looking lashes, for a satisfied client from the very first glance.

Unit of measurement = micron.

The numbers reported in the first column of the table represent some of the volunteers involved in the study, who underwent the Lash Filler treatment.

Here's what the acronyms used mean:

T0: diameter of the eyelash before starting the treatment, therefore in its natural, untreated state.

T1: lash diameter immediately after the first Lash Filler treatment.

T1': eyelash diameter 4 weeks after the first treatment.

T2: lash diameter after the second treatment.

T2': diameter detected 4 weeks after the second treatment, or 8 weeks after the first.

T3 : diameter after the third consecutive treatment.

Throughout the testing period, the volunteers avoided using any products that could affect the results : no mascara, growth serums, or similar cosmetics. The only product they used daily was a gentle makeup remover mousse from the same line, to ensure effective yet gentle cleansing.

I'd like to draw your attention in particular to the T1 and T2 data: these are measurements taken 4 and 8 weeks after the treatments. And it's precisely at that point that we can notice something extraordinary: the thickness of the lashes remains visibly increased even after some time, compared to the initial values ​​(T0). This clearly demonstrates that the filler not only effectively penetrates the hair, but remains sealed within the fiber, continuing to nourish and thicken the hair structure from the root, even in the following weeks.
