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/
