These ingredients are actually very easy to source. Apricot Kernel oil is a staple carrier oil for folks who maybe work in massage or aromatherapy so oils can be found in any good herbalist. Essential oils are also readily available too but quality varies a lot. Shea butter (and other sorts of butters) are available from almost all UK ingredient suppliers. Hoorah!
You can buy pipettes in most craft stores, they're just those little plastic dropper things. As I say, if you're at a lose ending finding products, just buy them online!
I am also wondering where to get some of these things. Where do you find the little tins? I am thinking you could find the oils and such at a specialty store like maybe whole foods, or perhaps at a craft store. When you say pipette, you mean like we use in the lab? Or some other more common item also called that. Haha. I just think of Micropipetters, but I am not sure how the average person would get one of those.
I like your version of lip balm, thanks!
