Always gently shake your natural fragrance before applying it.
Heat from skin causes the volatile oils to evaporate more quickly. Rather than spraying on your pulse points, try applying it to your hair, your beard, or fiber such as your clothing (bra straps, collar, scarf); the scent will last longer that way.
Always store out of sunlight and away from heat.
If a fragrance partially solidifies (i.e. it contains coconut oil), bring it back to a liquid state by placing the glass bottle in a warmer room or in a small ceramic or glass dish with warm -- not hot -- water in it.
