Our Story

From Sins 'n Lashes
to Sins Cosmetics

Our best eyelash serum...

It all began in 2022 – with a feeling that many people know:

Looking in the mirror and asking why your own natural lashes suddenly appear shorter, finer, or sparse.

Daily beauty routines such as lash lifting, eyelash extensions, mascara, eyelash curlers, fake lashes, or intensive makeup removal are a natural part of everyday life for many women. However, over a longer period of time, such routines can visibly strain the lashes. Small gaps in the lash line, brittle tips, or less volume – we have experienced it ourselves.

And that is exactly where the desire for an alternative arose.

At the same time, we repeatedly heard from people around us about experiences with conventional eyelash serums that were perceived as unpleasant – for example due to redness or sensitive skin reactions. For us, it was clear: If we develop our own eyelash serum for visibly longer and fuller-looking lashes, then with a different approach.

Our aim was never to promise miracles.

Our goal was to develop a formula that:

supports the natural care of the eyelashes
can contribute to a more well-groomed, fuller-looking appearance
is gentle on the sensitive eye area
can be easily integrated into any beauty routine

Together with our development team, we worked intensively on a formulation, carried out numerous tests, and carefully selected ingredients. The result was a mild, cosmetic formula focused on care and compatibility.

This first eyelash serum was more than just a product.

It was the beginning of Sins ’n Lashes – today Sins Cosmetics.

What began as a personal desire for more beautiful-looking lashes became a vision:

To develop beauty products that enhance natural radiance without making exaggerated promises.

Because for us, true beauty does not mean perfection – but confidence.

Lash lifting at home

After the positive experiences with our eyelash serum and visibly longer, fuller lashes, we wanted to take the next step: trying a lash lifting at home.

What started as a simple beauty idea turned into an experience we will never forget.

A conventional lash lifting set led to burnt lashes for us...

Our lashes appeared frizzy, dry, and significantly shorter than before. Instead of curl and definition, they looked heavily damaged.

Of course, every hair reacts differently. But for us it was clear:

This is not how a lash lift should feel. And that is exactly where our next mission began.

Anyone searching for “burnt lashes lash lifting” will find countless experience reports. Common causes can be incorrect processing times, unclear instructions, or strongly formulated solutions.

We realized that not only the formula is crucial – but also:

precise dosage
clear step-by-step instructions
transparent application
supporting aftercare

If you offer a lash lifting at home, you carry responsibility.

We wanted to develop a lash lifting kit for home that learns from our own experience.

Our focus was on:

carefully coordinated cosmetic formulations
precisely dosed bottles
a nourishing lotion after the lifting
a stable, high-quality storage box
an illustrated guide for maximum safety in application

Because we are convinced: A beautiful result begins with clarity and quality.

After our own lashes had gone through their natural growth cycle, we tested our set multiple times internally and optimized it step by step.

Only when we truly felt comfortable with the overall concept did we bring it to market.

In addition to our experience with burnt lashes, another point also played a role:

The costs of a lash lifting in a beauty or cosmetic salon.

Depending on the studio and region, the prices for a professional lash lift can occur regularly. For many, this means:

recurring appointments
ongoing salon costs
time dependency

For us personally, the desire for more flexibility arose.

A lash lifting at home can be an alternative – especially for those who want to organize their beauty routine independently and reduce salon costs in the long term.

Our lash lifting was created from an honest experience – with burnt lashes, with disappointment, and with the desire for a better solution...

How our eyebrow serum was created...

After the success of our eyelash serum, it was clear to us: the topic of natural growth does not stop at the eyelashes. Every day, we received messages from customers who were thrilled with longer, fuller lashes – and at the same time asked: “Is there something like this for eyebrows as well?”

Many women struggle with sparse eyebrows, over-plucked brows, or fine hairs that simply do not grow back properly. Yet full, beautiful eyebrows are essential for the overall appearance of the face. They create that natural, confident look – without the need for constant filling in or microblading.

This is exactly where the idea for our eyebrow serum began.

From our eyelash serum, we already knew how important a well-thought-out combination of ingredients is for visible growth. So we asked ourselves: how can we develop an eyebrow serum for potentially more growth and density that is just as effective, but specifically tailored to the needs of eyebrows?

Our goal was clear. A serum that:
• supports natural eyebrow growth
• helps with sparse eyebrows
• creates fuller and thicker brows
• is easy to use
• and integrates seamlessly into any beauty routine

After an intensive development phase, our eyebrow serum was created – inspired by the wishes of our community.

Today, our eyebrow serum is a fixed part of the routine for many customers. Because sometimes it only takes the right product to unlock the full potential of your natural beauty.

And that is exactly what we stand for with Sins ‘n Lashes - Sins Cosmetics

After our eyelash serum became part of the daily routine for many people, we had the idea to develop a mascara that is also good for the lashes and supports them passively throughout the entire day.

Mascara is part of the daily beauty routine for many people. It creates more expression, enhances the eyes, and makes the lashes appear immediately longer and more defined. At the same time, we heard from many customers that they wanted a mascara that not only looks convincing but also feels comfortable on the lashes.

This is exactly where the idea of our Vitamin Growth Mascara was created.

Our goal was to develop a mascara that combines two things:

intense color in black and brown for defined, enhanced lashes
a formula that feels light and comfortable on the lashes

During development, we placed great importance on a texture that visibly separates the lashes and gives them definition without unnecessarily weighing them down or sticking them together.

The brush was just as important to us. It should reach every single lash, provide more definition, and emphasize the natural lash line.

The name Vitamin Growth Mascara represents our approach of combining makeup and care. For us, mascara is not just color – but a product that integrates harmoniously into the daily lash routine.

After many tests and adjustments, a mascara was finally created that quickly became a fixed part of our product line.

Because sometimes it is exactly the small steps in the daily routine – a serum in the evening and a mascara in the morning – that change the overall result.

After our products for lashes and eyebrows became more and more part of the daily beauty routine of our community, we started receiving similar questions more frequently.

Many customers did not only write to us about their lashes – but also about their hair.

Messages such as:

“Do you also have something for dry hair?”
“Is there a good hair oil for more care and shine?”
“Are you planning a rosemary oil for hair?”

These conversations showed us that the topic of natural hair care is just as important to many women as beautiful lashes and eyebrows.

Just like lashes, hair can also be heavily affected by daily routines:

Heat from styling tools, frequent washing, coloring, or external environmental factors can cause hair to appear dry, brittle, or dull.

For us, it was clear: If we enter this category, we will do so with the same standards as before.

The first step in our hair care category was a high-quality hair oil.

Our goal was to develop a care formula that can be used in many ways within a hair routine – for example:

as care before washing the hair
as oil for the hair lengths
as a finish for more shine
or as part of a regular hair care routine

During development, our focus was on a pleasantly light texture that distributes well and can make the hair look cared for without weighing it down.

At the same time, one topic came up more and more frequently: rosemary oil for hair.

Rosemary oil has a long tradition in the world of hair care and is used in many routines – especially as part of scalp massages or as a nourishing hair oil.

Due to the many requests from our community, the idea arose to also develop a rosemary oil for hair that can be easily integrated into different hair care routines.

Our brand started with the goal of supporting natural beauty – starting with lashes. But it quickly became clear that many women want to consciously design their entire beauty routine.

That is why it was a natural next step for us to develop products that can also become part of this routine in the area of hair care, hair oil, and rosemary oil for hair.

And this is exactly where the next chapter of our journey began.

After our hair oil and our rosemary oil became part of the regular hair care routine for many, we wanted to further develop our routine. We asked ourselves a simple question: What is still missing to make daily hair care even easier?

Many hair oils are especially used for lengths and ends. At the same time, we were looking for a product that can be easily integrated into everyday life without weighing the hair down or leaving a heavy feeling.

This is exactly how the idea of our hair serum was created.

Our goal was to develop a formula that clearly differs from classic hair oils. A light, pleasant texture that is easy to apply and absorbs quickly. It was especially important to us that the serum does not feel greasy and that the hair can still look natural and well cared for.

During development, we focused on three things:

a light texture that distributes easily
a pleasant scent suitable for everyday use
an application that can be easily integrated into any hair care routine

Because hair care should not feel complicated. It should simply be part of everyday life – in the morning before styling, in between, or as an addition to an existing routine.

With our hair serum, we wanted to close exactly this gap: a product that is easy to use, makes the hair look cared for, and fits seamlessly into the daily beauty routine.

This is how our product world continues to grow step by step – always with the same idea with which everything began: to develop products that integrate naturally into everyday life.

And this is exactly how the story of Sins ’n Lashes – Sins Cosmetics continues.
