Mentoring Program

From formula to strategy — from product to brand with long-term direction

Welcome to the new generation of the Mentoring Program.

When we started the Mentoring Program a few years ago, the idea was to transfer knowledge about cosmetic product development to people who want to make something of their own.

Today, after eight generations of participants, numerous products that have passed through our laboratory, and brands that I have had the opportunity to follow from the first idea to the market, I look at this program much more broadly.

Because in the meantime, I’ve learned something very important: making a good cosmetic product is actually only one small part of creating a successful beauty business.

You can make a fantastic cream, you can have great active ingredients, a beautiful texture and packaging that looks perfect, but if you don’t know who you’re selling the product to, why someone would buy it, how much it really costs you, how much money is left after you sell it, through which channel you will reach the customer and how many you will have to sell for the whole story to make economic sense, you simply don’t have a business. You have a product.

And it is precisely this difference that became the foundation of what I want the Mentoring Program to be today, which is why we created the Beauty Startup Bootcamp .

Before we talk about emulsifiers, active ingredients, preservatives and formulations, I want to talk about the market, I want to ask those questions that are not always pleasant, but are necessary.

Who is your customer? What problem do you solve for them? Are there enough people who have that problem? What are they already buying? Why should they buy from you instead? How much are they willing to pay? How much can your product cost? What should your margin be? What happens to that margin when a distributor, pharmacy, or retailer comes into the picture? What is your MOQ? How much capital do you have to commit to the first production run? How long can that money be tied up in inventory?

And perhaps the most important question of all: Are we building a product or are we building a business? Because they are not the same.

That is exactly why I want to say very clearly who the 9th generation of the Mentoring Program is intended for.

This is not a program for DIY cosmetics enthusiasts, and there’s nothing wrong with that. Loving to formulate, research ingredients, and make cosmetics for yourself is a wonderful hobby, and there are training courses designed specifically for that.

But the Mentoring Program is not that kind of education.

In the 9th generation, we create new value and build a business from it.

Maybe you have an idea for your first product, maybe you already have a small brand and you’ve realized that you can no longer make decisions intuitively. Maybe you want to manufacture your own products, maybe you want to enter pharmacies, retail or another market. Or maybe you don’t even have a brand name yet, but you know you want to build a serious beauty business.

Then we need to talk about much more than just the formulation.

We need to understand the market, the competition and the consumer, we need to know how to make a financial construction of the product, determine the price, understand rebates, margins and profitability. We need to talk about positioning, sales, webshop, retail, marketing and communication. And then we need to understand what we are selling equally seriously.

And that’s where we get into the nitty-gritty.

The skin. Raw materials. Formulations. Active ingredients. Product development. Stability. Microbiology. Challenge tests. Dermatological tests. Packaging. Regulation. Safety Assessment. PIF. CPNP. GMP.

Not because I think a beauty brand owner has to stand behind a homogenizer their entire life, but because I think they have to understand their own product well enough to be able to make good business decisions about it.

He must be able to talk to the formulator, the manufacturer, the Safety Assessor, the packaging supplier, the designer, the distributor and the customer. He must understand why something costs what it does, why something lasts for months, why we can’t write a certain claim on the packaging and why a product that looks perfect after two days may not look that way after six months.

And then we come to the laboratory.

Because no matter how much you talk about a product, some things you have to see, do, and make mistakes with your own hands to truly understand them. And that’s why the Mentoring Program today is no longer an education about cosmetics formulation for me.

It is an education on creating a beauty business. From the idea, through the market and business model, to product development, production and the moment when that product needs to find its customer.

After eight generations, maybe that’s the biggest change in the way I look at this program, because I don’t want you to come out of it with just wording.

I want you to come out able to look at an idea and assess whether it makes business sense. I want you to know how to spot a mistake before it costs you thousands of euros. I want you to understand numbers as seriously as you understand the INCI list. And I want you to know that one day, when your product is sitting on a pharmacy shelf, a grocery store shelf, or someone’s bathroom cabinet, you know why it’s there and how you got it there.

That is why we are opening enrollments in the 9th generation of the Mireille Lab Mentoring Program.

We don’t build people who just want to learn how to make cosmetics, we build people who want to make something out of cosmetics.

If your goal is to create a product, build a brand, and turn it into a sustainable business; then we have something to talk about.

The Mireille Lab mentoring program begins with a new, strategic cycle – one in which we no longer start from the product, but from the foundation of the business. Because a successful brand is not created by chance, but from an understanding of why, how and with whom we want to do business.

Through eight carefully designed topics, we will learn how to define our own direction, build a brand structure and make smart decisions – from price to placement, from strategy to marketing. The program guides us from key business decisions to concrete tools that precede the actual development of products and formulations.

Together, we discover what type of business suits you best – a boutique brand, production for others or a retail brand with greater potential. We analyze the marketing path (online, B2B, B2C, retail, drugstores, pharmacies), form realistic and sustainable prices, learn what it means to “list”, how to build trust through branding and social networks, and how to set up a webshop as a sales tool and communication channel.

Mentoring program cycle

Eight new units

  • Understanding your own strategy and making business decisions based on vision, mission and goals.
  • The process of listing in retail, with an emphasis on technical, legal and marketing prerequisites, negotiations and rebates.
  • Financial construction of the business – price calculation, cost planning and profitability assessment.
  • Discovering market potential and identifying “holes” in the market where your brand has an opportunity to grow.
  • The ten most common mistakes in online sales, through practical examples and analysis of webshop experience.
  • Branding as a foundation of trust – defining identity, tone of communication and emotional connection.
  • Strategic positioning of the web shop as a mirror of the business concept and the digital experience it sells.
  • A marketing strategy that delivers real results, not just presence.

The goal of the program is for you to understand the foundations of your business before you define a product – so that every decision you make has purpose and strategy, not coincidence.

Enter the world of cosmetics

The world of creating cosmetics is a world of play and imagination, creativity and opportunities to explore the world around us, but it is also a world with a lot of unknowns, a lot of small obstacles on the road that accumulate and should be approached expertly and professionally. The search for these answers is often difficult and painstaking because the information is often unavailable, half-hearted and confusing.

Program objective

Its goal is to guide small producers and those who want to become one on the path to a product with as few mistakes and doubts as possible, thus saving time and money and bringing a complete brand with fruitful products to the market. Cosmetics will be made in accordance with global standards, and team members will learn best practices and receive recommendations for the use of each of the products made.

Quality

If you believe in quality, knowledge, and authenticity – the Mireille Lab Mentoring Program will help you turn that into a real, market-ready product. Because behind every successful brand is knowledge – and behind knowledge, a real mentor.
Professional part

When vision becomes formulation

After defining the direction, strategy, and business framework of the brand, we enter the second phase of the program – the professional, laboratory part. This is the moment when the idea becomes a concrete, functional, and safe cosmetic product.

Through this phase, we understand each layer – from skin to formulation, from ingredients to legal documentation. We learn:

  • Skin structure and function, anatomy and physiology, and the influence of active ingredients.
  • Shapes and types of cosmetic products (creams, serums, emulsions, gels, tonics, balms…) and how to choose the ideal format.
  • Ingredients – from functional to active, their synergy and stability in the formula.
  • Examinations and testing of products (stability, microbiology, dermatological tests, challenge tests).
  • Legal regulations and documentation, EU Regulation 1223/2009, PIF documentation, CPNP applications and ISO standards.
  • The laboratory-to-market process, including packaging selection, batch validation and GMP quality control.

The goal of the professional part is for you to know how to build a product that has purpose, structure and security – and that perfectly matches your business strategy.

Your brand could be next

Practical part

When knowledge becomes experience

The third phase of the program takes place in the real Mireille Lab, where knowledge is turned into practice. Through a series of guided laboratory modules, participants develop real formulations, from concept to finished product, with expert mentoring and supervision. We learn:

  • Introduction to laboratory work and safety according to ISO 22716 standards.
  • Formulation exercises on different forms of products (emulsions, gels, oils, masks, scrubs).
  • Technological processes and production stages (heating, dispersion, homogenization, cooling, conservation).
  • Analysis and correction of formulations, error recognition and process optimization.
  • From the laboratory to the finished product, including filling, labeling and GMP documentation.

The goal of the practical part is for knowledge to become a skill – for each participant to understand the entirety of product creation, from idea to market, with a professional approach and understanding of responsibility.

Mireille Lab

Mentoring Program

The Mireille Lab Mentoring Program connects three phases that make up a whole:

  • Strategy – understanding where we are going.
  • Profession – knowing how to create.
  • Practice – learning to actually do it.

That’s the path from idea to brand.
This is Mireille Lab.

Aspects of manufacturing, pre-market testing, marketing strategy, and budget for a product launch are also considered. The lecture provides a comprehensive insight into the planning and execution of product development.

The lecture “Theoretical part: Instructions & guidelines for cosmetic product development” provides practical advice to participants on key aspects of cosmetic product development. During the lectures, the importance of balancing between the quality and cost of raw materials, as well as the optimization of formulations to make the product economically profitable, but also efficient, is emphasized.

  • Monitoring raw material prices: Participants are advised to regularly monitor the raw material market in order to be able to effectively manage costs and avoid potential financial losses due to price fluctuations.
  • Product ‘Fundamentals’: Emphasizes the importance of adding substantial ingredients that provide real value to the product. Participants learn how to avoid ‘diluting’ a product by ineffective or excessive use of expensive active ingredients that do not add real value.
  • Moderation with Active Ingredients: The importance of the correct amount of active ingredients is discussed in detail. Too many active ingredients can lead to product stability problems or potential irritations for the user, so participants are advised on how to optimally balance efficacy and safety.

The lecture focuses on Good Manufacturing Practices (GMP) standards in the cosmetics industry, emphasizing the importance of product quality and safety. Key topics include:

  • Introduction to GMP – The importance of GMP for quality and safety, and an overview of regulatory requirements.

  • Raw materials and storage – Protocols for receiving, storing and handling raw materials.
  • Production process, development of SOPs – Overview of production stages from mixing to packaging, with an emphasis on documentation and consistency.

The aim of the lecture is to ensure understanding and proper implementation of GMP principles so that products are safe and of high quality.

In this module, participants will learn about key laboratory techniques that are essential for ensuring the quality of cosmetic products. Why is it important, what does it prove and show us, where are such tests performed, why is it necessary to perform them according to SOP?

The lecture “Current upcoming trends in the cosmetics industry” provides participants with an insight into the latest innovations, consumer habits and technological advances that shape the future of the cosmetics industry. The aim of the lecture is to equip participants with knowledge about how trend predictions can influence product development and marketing strategies.

Additional lectures:

  • Social networks and social media sales
  • Sales funnel
  • Design
  • Photo
  • Media

The theoretical part is held via the Zoom application, it is recorded and remains the permanent property of each participant

Each participant has 90 minutes available for individual consultations with the program manager, and before that they sign an NDA with the company to keep the exchange of information confidential.

Practical part

We work according to the principles of ISO 22716 (Good Manufacturing Practice), from hygiene and safety protocols to proper preparation, measurement and documentation.

Practical work on various forms of cosmetic products: emulsions, serums, gels, tonics, oils, masks, scrubs…

Participants learn to select raw materials, calculate percentages, measure pH, stability and texture, and recognize what the formula “says”.

Through practical work, we go through the stages of heating, dispersion, homogenization, cooling and preservation, while understanding the role of each step. The emphasis is on precision, documentation and process standardization.

Each formulation undergoes an analytical approach: stability, appearance, texture, scent, skin feel and compatibility with packaging. Participants learn to recognize mistakes and learn from them, just like in real production.

The final step includes filling, labeling and maintaining GMP documentation, so that participants understand the process from sample to market-ready product. The emphasis is on quality control, traceability and readiness for PIF documentation.
