Only use half of the bottle if the air in your home is dry because the diffusion will be slower and last longer. Determine the intensity of the fragrance according to your preferences. You should use only a few of the sticks for a light and gradual diffusion. Use all of the sticks for a more intense fragrance. Position your diffuser next to a heat source to increase the diffusion of the fragrance. Turn over the sticks once a week to intensify the fragrance.
