These are skin friendly oils with molecules ending in “-ol” such as Linalol (in Lavender angustifolia), Geraniol (in Geranium and Palmarosa), and Terpinen-4-ol (in Tea Tree and Sweet Marjoram). Monoterpenols are good choices for skin nourishment, inflamed skin from poison ivy, sunburn, or rashes. They are also great immune system stimulants. As always, see individual oil profiles for specific uses.
