Essential Formulation:

Oil-Based Products and Aqueous Sprays

How many times have you poured a liquid balm into a container to set – its surface smooth as glass – only to find later that it’s gone grainy or is dotted with hard waxy nubs? Have you ever wondered how to write a proper formula or add 0.15% of antioxidant to a product? Should you be adding essential oils straight into your bath salts or facial mist? (Hard no.)

Whether you’re an aromatherapy practitioner striving to create professional bases for your therapeutic blends, or a cosmetic formulator aiming to make luxurious products, this eight-week online certification course is for you.

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 several 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 personally guides 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.

What previous students say about this course:

This course was so complete and easy to follow. I loved the live webinars with Lisa and Robert (Lesson 2) and appreciated the structured classroom, as I have discovered that I do best in this type of setting. Also, thank you so much to Hana for her support, input and knowledge for each lesson! ~ Darlene Sekijima
I so enjoyed Lise’s personality and the banter between Hana and Lise. I have a very high stress life, and many times Lise, and Lise and Hana put a smile on my face or made me chuckle when I needed it most. Better than CBD! ~ Sheila McKenna
I appreciated the passion that was put into the course. I stumbled across this by chance and I am so thankful I did. This has expanded my passion and knowledge about formulations. It has enhanced my learning about essential oils. I just want to thank you for offering this course and all that you do. I feel so confident having your institute as my education platform. I am a beginner but feel confident with your amazing education that it wont be long before I am a pro!! ~ Penny Ferguson
The personalized attention and friendly feel. Sometimes you feel like instructors are holding back their best secrets or knowledge. But I didn’t feel like that with either Lise or Robert. Lise was delightful. I felt like I could just pull up a chair with a cup of tea and we could talk formulations! Also being able to learn about blending from Robert was an incredible treat! I would love to have a larger course about that!! ~ Kristi Maxwell
I loved the way the information was organized and the depth of information. I can do some real formulating now- like a pro! I also just love the “freshness” of Lisa and Hana, and the calmness of Robert. What a great team! I also SO appreciate the ongoing feeling that I am dealing with experts when dealing with Tisserand Institute. Thank you! ~ Tina Hammer
I really liked that we had the options to view live or on our own time. This was amazing as my schedule is very volatile and I wasn’t able to be there at the scheduled time as I thought I would. I really like Lisa and thought she was a fun and engaging teacher. I like the video format as well, so that I am engaged visually and can listen, because if it’s just one or the other I find I get distracted too easily. I also liked that some basic formulas were provided to get beginners started with the types of formulas that they are not familiar with. ~ Michaela
Friendly and fun, very well explained. Loved the course – thank you ~ Lilly Zoch
I thoroughly enjoyed this class! Felt like I was right in the same room and also appreciated the candor and humor. There was so much valuable information given by both Lise and Robert.
Not one thing – EVERYTHING! with all my TI courses. Quality of course content, facilitators, teachers and their knowledge, teaching platform – everything! ~ Niki Klelin
The dynamic between Lise and Hana was wonderful — it caused this course to be fun, interactive and so engaging. I’d subscribe to their podcast, if they had one. ~ Rhonda M
I notice I have been mulling things over a lot from this course and that more has gone in than I thought. I’m having my own distilled understandings arriving – which is proof of quality education. Overall i think it was a very good course and that your online platform is superb – as good as any I have used. ~ Nigel Sutton
This is a rare opportunity to study with one of the world’s leading experts on essential oils – don’t miss this chance! Let Robert Tisserand guide you in creating safe and effective blends with parameters based on clinical trials and scientific research.

FAQs

Will there be notes for me to review?
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.
I am a certified aromatherapist. Will I learn anything new?
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.
I am new to essential oils. Is this course for me?
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.”

Will there be assessments or exams? What kind?
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.
When will the live Q&As take place?
There will be five live sessions. You can ask questions any time on our online platform.
Will I be able to ask questions?
Absolutely! In addition to the live Q&A sessions, you can post your questions in the dedicated student forums.
I’m only interested in skin care, do I really need to know about all the safety aspects?
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.
How long will I have access to the recordings?
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.
I have already done the Essential Oil Safety Masterclass. What do I do?
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. 🙂
How is Essential Oils for Healthy Skin different to the “Complete Skin Series”?
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.
Do you offer continuing education credits?
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.
What if I fall behind or cannot attend classes?
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.
