It’s important to us that you feel supported during your studies with us and several avenues of assistance are available to you.

  1. Technical/administrative help

Our customer service team is on hand if you require help with technical or administrative matters.

  1. Tutor support

To provide you with the best support, we have experienced formulation tutors available within our student support group (hosted as a private Facebook group) to answer your questions. To ensure we answer your questions efficiently and effectively we invite questions from students on specific days of the week in allocated Tutor Q&A posts.

  1. Peer support

The Diploma in Natural Skincare Formulation has its own private support group (hosted on Facebook) where you can meet and spend time with your student peers.

This is the perfect opportunity to start marketing your business and gain your own following.

It typically takes students 70-150 hours to complete the Diploma in Natural Skincare Formulation. The amount of time it will take you will depend on how much practical formulating you choose to do, so you may wish to spend more or less time than this. Most students complete the course within six to 12 months. As it is a self-paced course, you can complete it at a speed that suits your schedule. 

A variety of formats are used including comprehensive and beautifully designed course textbooks (provided as PDFs), workbooks and worksheets, video lessons, video demonstrations, quizzes and activities.

To get started you can use some basic kitchen equipment that you use solely for the purpose of cosmetic making. Here is a list of the equipment that you should consider using:

  • Protective clothing.
  • A bain-marie or water bath for a source of heat.
  • Pyrex bowls or glass lab beakers.
  • A thermometer.
  • A stick blender (immersion blender).
  • Digital scales.
  • Small beakers/weighing boats/pipettes.
  • Whisk/spoons/spatulas.
  • pH strips (or meter).
  • An electric hand whisk.
  • A heat-resistant mixing bowl.
  • Sufficient packaging.

We have a blog article and video that you may find useful on the equipment you need to get started:

www.schoolofnaturalskincare.com/equipment-you-need-making-natural-skincare-products-home/

We go into much more detail about the equipment you need in the Diploma in Natural Skincare Formulation.

If you want a more professional lab setup you can purchase professional pieces of equipment which we can advise you about when you join the course. This is not necessary, however, as in many cases kitchen equipment is more than adequate.

As part of the course you receive a comprehensive global supplier list featuring hundreds of cosmetic suppliers, many of which deliver internationally.

We also have a smaller supplier list on our website you might want to look at in the meantime:

www.schoolofnaturalskincare.com/recipes-info/recommended-suppliers/

The majority of ingredients used are available in most countries around the world.  In some cases, if you wish to use specialist ingredients (such as emulsifiers and preservatives) you may need to order from overseas suppliers.

The Certificate in Making Natural Skincare Products is a short beginners course that teaches you how to make products using lovely natural ingredients following our recipes. The Diploma in Natural Skincare Formulation teaches you how to formulate or design your own unique products, and make them to a professional standard. The course contents are greater and more in depth and take your skills and knowledge to a more advanced level.

If your goal is to formulate products from scratch, understand in more detail the science of cosmetic formulation, use more advanced ingredients and/or sell your products, then we recommend the Diploma in Natural Skincare Formulation.

Both courses can be taken as a beginner, so which one is right for you is more about where you want to end up than where you are starting from.

We have written an article that helps explain this further: Choosing between our skincare Certificate or Diploma – which course is right for you? https://www.schoolofnaturalskincare.com/difference-between-certificate-and-diploma/

The course curriculum is vast! To enable you to gain the most from it we are releasing new content from the course each week. On average you’ll receive one new module from the Diploma in Natural Skincare Formulation (Third Edition) each week starting on 26th October 2020.
