Domande Frequenti

What are top, middle, and base notes?
Top notes (citrus, herbs) are the first impression, evaporating quickly. Middle notes (florals, spices) form the heart of the blend. Base notes (woods, resins) are the lasting foundation.
What dilution percentage is safe for skin?
For adults: 1–3% for body blends, 0.5–1% for face, 5–10% for targeted muscle relief. Always research individual oils for specific safety limits.
How many drops are in 1 ml?
Approximately 20 drops per ml is the standard assumption for essential oils, though this varies slightly by viscosity.
