Add the sugar to a container, then add the oil, and finally stir until well combined.
You’re looking for a sandy consistency, otherwise, if the scrub is too soupy, the sugar will dissolve in 1-2 days.
This homemade sugar scrub is very easy to store. As it'll probably be a part of your beauty routine, I suggest you keep it in an airtight small mason jar or just a regular jar (as long as it's sealed) in a cabinet in your bathroom. It'll last for up to 1 month.
Notes
Whether you incorporate essential oils or not, don't eat your DIY sugar scrub. Research which oils or essential oils you can use if you're pregnant.
Do not use it every day but up to 3 times a week at most.
