    If you need more help please reach out to our customer service team at

    How much prior experience is required?

    This is our most advanced course so it is not suitable for complete beginners. 

    If you have some experience of making skincare products already, for example you have made facial oils, balms, creams and lotions, and you are ready to study and formulate more seriously then the course will be suitable for you.

    If you are an experienced formulator but have yet to formulate with a wide range of actives, or you want more knowledge of how to do so, then the course is also perfect for you.

    If you are a complete beginner then we recommend that you take either our Certificate in Making Natural Skincare Products or our Diploma in Natural Skincare Formulation first. You can enroll on a special Serum and Skincare Bundle that contains our Diploma in Natural Skincare Formulation and our Advanced Certificate in High-Performance Serum Formulation at a reduced fee. This is perfect if you’d like to take this course but you don’t have any prior experience.

    Are all the ingredients in the course natural?

    In our courses in general we always focus primarily on natural ingredients and use close to 100% naturally derived or COSMOS approved ingredients. In the Advanced Certificate in High-Performance Serum Formulation the vast majority (around 90%) of ingredients we use are naturally derived and permitted by the major natural and organic standards such as COSMOS. We include a wide range of natural emulsifiers, solubilizers, gums, thickeners, carrier oils, esters, fragrances, botanical extracts, humectants, antioxidants and other active ingredients.

    In the Advanced Certificate in High-Performance Serum Formulation a small number (around 10%) of the ingredients we include are synthetic. We have only chosen synthetic ingredients with close ties to nature, for example they exist in nature but are made synthetically or are “nature-identical”. Two examples are niacinamide (Vitamin B3) which is often used in natural cosmetics as it does exist in nature but the ingredient is made synthetically and peptides which are not permitted in natural/organic certifications because they are made synthetically, even though they only contain naturally occurring building blocks (amino acids).

    We have included these ingredients as we wanted to include a wide range of the most popular and effective active ingredients. Our chosen ingredients have a specific benefit/activity that is very important in high-performance serums, but can’t be found in any natural form/source. Any ingredients that are synthetic are clearly marked as such in our course materials, giving you full knowledge and complete control over what you use in your formulations. 

    We like to put the power and the choice in your hands! So you can absolutely take the course and create formulations that are 100% natural or organic or suitable for COSMOS certification if you wish. 

    Is the course accredited?

    Yes! The Advanced Certificate in High-Performance Serum Formulation is accredited by the CPD (Continuing Professional Development) Certification Service.

    The CPD Certification Service is the leading independent CPD accreditation institution operating across industry sectors. They are a globally recognized institution and accredit courses by prestigious organisations including the University of Westminster and the London School of Economics – and ours, too!   The CPD Certification Service assesses each course individually, evaluating the quality of training materials and learning activities against the highest standards.   We are delighted to have passed the formal and impartial CPD accreditation process carried out by the team of experienced assessors at the CPD Certification Service. See our Accreditations and Memberships page for more information on our professional memberships and accreditations.

    I live in Australia/USA/India/ _______ (insert country here). Can I still take the course?

    Yes! The course is a fully online training program that consists of online training videos, downloadable workbooks and worksheets and an online student support group. It is designed to be taken from home from anywhere in the world and the products we make meet global quality and safety standards. We’ll provide information on ingredient suppliers in many different countries. We have students in over 120 countries so you’ll be joining a thriving community of global students when you join!

    Are there any assignments? Will I get a certificate at the end?

    Yes, when you have finished the course there will be several assignments to submit. These are straightforward to complete and based on the material covered in the class. On successful completion, your course certificate will be issued.

    What help is available if I need it?

    The course is primarily designed as a self-study course. It takes a very thorough step-by-step approach and each module builds on the next. Therefore as you progress through the course you’ll gain the skills and knowledge needed to become an expert formulator. When you sign up to the course you also get to join our private online student community (hosted via Facebook) to meet and discuss with other students, who have lots of knowledge, expertise and ideas to share. There we also host a weekly Q & A with our Formulation Tutor, who can answer any questions you have as you work through the course.

    Are there set lessons to do on specific days or can you do it in your own time?
