The ingredients you need will depend on what you want to make.
To give you an idea, to try out making facial oils, balms, body butters and creams/lotions you can begin with just a few ingredients, for example two to four carrier oils, two to four essential oils, a butter, a wax, an emulsifier and a preservative. From there you can gradually get more as you want to try making different products. Many of the recipes need similar ingredients so once you have a few supplies there are lots of recipes you can try. Alternatively, you can stock up at the beginning. The choice is yours.
If you are on a budget you can certainly practice first with less expensive carrier oils and essential oils.
