Roller bottles are one of the easiest ways to tap into the many benefits of essential oils. Because essential oils are highly concentrated plant extracts, it’s not always safe to apply the oils directly to your skin. That’s where roller bottles come in; they’re one of the gentlest ways to apply essential oils. Add a few drops of your favorite essential oils to your bottle, dilute with a carrier oil, and your roller is ready to go! We lay out step-by-step instructions on how to build your roller bottles here.
