Essential oil molecules can be grouped into 4 key families.
Remember this simple rule — one sentence to understand their main functions, no more blindly following trends:
Terpenes — uplifting and antimicrobial
Alcohols — gentle, skin-friendly, and antimicrobial
Sesquiterpenes — calming and restorative
Esters — relaxing and sleep-supporting
Once you understand this structure,
you’ll start to see essential oils in a completely different way.
