This is a personal diffuser with our phenomenal essential oil blend named "HAPPY ME.” It will make you feel so much better without you're feeling depressed, sad, or just not up to par. The science behind this amazing formula increases your endorphins in your brain. This gives you an uplifting feeling. Six to Eight puffs seem to give immediate relief. We also suggest if either of these work for you that you also put our blended oils in your house diffusers. CAUTION: Always use distilled water in any diffuser.
