Aromatic Formulation Program

We believe that formulation skills are essential.

The two courses that comprise Aromatic Formulation give you the solid knowledge base you need to start formulating your own face and body care products. Join Robert Tisserand and Lise Andersen, who will guide you through a range of expert creations for you to add to your aromatherapy toolkit. Four months of step-by-step instruction, filled with customizable formulas for balms, salves, masks… and now also emulsions!

This is an eight week course. During seven fascinating lessons, expert cosmetic formulator Lise Andersen will share her passion, know-how and professional techniques for creating silken whips, balms, serums, mists and more. You’ll explore the pros and pitfalls of plant oils, waxes and butters, and discover how and where to procure the right equipment and fresh, raw ingredients.

There is also one lesson on Essential Oil Blending with Robert Tisserand. Offered in week two, Robert will personally guide you in creating safe and beautifully scented therapeutic and cosmeceutical blends for adding to your formulations.

As well as gaining the proper methodology for custom formulating, you’ll get dozens of smart tested formulas, including essential oil blends designed by Robert. Stop relying on dubious DIY recipes that are potentially ineffective or unsafe, and confidently create your own sound formulations.

Completion of this course is a prerequisite for Level 2 – Emulsion Essentials.

In this four week course, Lise Andersen expertly walks you through the process and equips you with the knowledge to make your own safe, stable, hand-stirred emulsions without having to invest in pricey lab equipment.
Lise has carefully selected ingredients that are globally available, easy to work with, and that can be combined using regular kitchen tools and equipment. She shares her many tried and tested techniques and provides you with insights you’ll need to continue your emulsion-making journey with confidence. You’ll get step by step instructions and six unique formulations from eye serum to face cleanser to rich soothing salve.

You’ll learn how to work with six different emulsifiers and get comfortable about using preservatives while creating a collection of beautiful products that are as natural is it’s possible to be.

Ready to get started?


Yes. Each lesson comes with printable handouts of the slides used in the lesson, and additional lesson notes. These are sent to you before each lesson and are for you to keep and refer to at any time.Many of our students have commented that our courses helped them grasp what they learned elsewhere in more detail, or complemented their previous education. Some of our students are lifelong learners, and some are teachers.We will let one of our previous students answer this one:

“The information presented is appropriate for all levels, and although I am just beginning my aromatherapy journey it all makes sense.”Each weekly lesson is followed by a multiple choice quiz, and there is a summary test at the end of each course. Passing both the weekly quizzes and the final tests is a requirement for certification.There will be five live sessions. You can ask questions any time on our online platform.Absolutely! In addition to the live Q&A sessions, you can post your questions in the dedicated student forums.We believe that safety should be at the core of any practice using essential oils. This is why we require those who wish to study Essential Oils for Healthy Skin to also pass our Essential Oil Safety Masterclass. This ensures that the knowledge you gain can be applied safely as well as effectively. Understanding essential oil safety from all angles helps you make safe choices for yourself, your family and/or your clients.You will have access to all the recordings and course materials for at least twelve weeks weeks after the last lesson. All the printable materials (notes, handouts, charts, etc.) are of course yours to keep for reference forever.You don’t need to do the Safety Masterclass again, but we will open it for you as a sit-in to refresh your memory for no extra cost – you just pay for the Skin part. If you have purchased the Safety Masterclass before but did not get the Certificate of Completion, you can use this opportunity to do so. Please check your email for a message about how to proceed. 🙂Essential Oils for Healthy Skin is an update of the Complete Skin Series, which was launched in 2014. It not only includes much new information, but it is now a certification course. There are recorded lessons and live Q&A sessions, and you will need to pass the assessments to gain your certificate. This all happens on our new learning portal where you can interact with fellow students as well as ask questions in dedicated forums.Because we have students from all over the world and of many professions we are not able to offer credits for specific organizations – there are simply too many. However, we issue a confirmation of CE hours gained on the course that you can apply with your professional organization and will be happy to assist with any additional documentation.We have found that running classes on specific dates works best to help you finish a program. You join a class of students, and learn along with them. Many students help each other with queries, and of course our tutors are there too. That said, if you miss a few classes you should be still able to comfortably jump right back in and if you do fall behind you can request extra time. Of course this cannot be indefinite, but we do our best to help you get your certificate.
