After an essential oil mixture is stored in a bottle, do you have to use solid amounts each time?

Like, should you use 2 tablespoons each time or doesn't it matter at all as long as the dilution of the essential oil to the carrier oil(s) was correct when you first put it in?After an essential oil mixture is stored in a bottle, do you have to use solid amounts each time?
If you have a 3% dilution, for instance, it's going to be a 3% dilution whether you use a teaspoon, or a tablespoon, or a bloop.





But, you'll want to keep in mind the oils you're using and what you're using them for.





Something like diluted cinnamon or peppermint oil might be ok using a drop or two, but all over your body it would be too much, where something like lavender would be ok for all-over use.





Just pay attention to oil safety, and always use your intuition. If the smell, say, gives you a headache or irritates you in any way, either use less of the diluted oil, dilute it further, or stop using it altogether.
