...but not quite after all of them.

15 ml sunflower seed oil (carrier)

2 drops sandalwood
2 drops German chamomile (next time I do this, I must get the digital camera with the close-up on: the midnight-blue of the chamomile shows some very interesting flows and different densities... it's a wonder I didn't become a chemist, seeing this stuff - probably overprotective parenting.)
4 drops lemon (just because I was feeling citrus-y and thinking, "Photosensitizing? Not a worry when it's subzero in January.")
