One of the most exciting parts of your PSK is the diffuser! There are so many wonderful options (the one above is the coveted Aria diffuser) but I love my Desert Mist! Just plug it in, add a few drops of oils - Stress Away or Thieves are great options, add water to the fill line and turn on!
You want to make sure you clean your diffuser every so often to avoid any build up from the oils or water depending on the water you use.
I always start with a few drops (3-4) and add more if necessary to get the desired effect. Check out the blog for some fun diffuser blends and get inspired. You can come up with some amazing combinations that not only smell wonderful but help support your body as well!
