Tips and safety notes
- Always start with a conservative dilution, especially for sensitive populations (0.5–1% where advised by NAHA/Tisserand guidelines).
- Patch test new blends on clean skin before broader use.
- Phototoxic oils (like certain citrus) may require lower dilutions; avoid sun exposure after application if using photosensitive oils.
- For adults, 2% dilution is a common general-use guideline; adjust downward for children, the elderly, pregnancy, or compromised skin.
- When estimating drops, remember that 20 drops/mL is a common baseline, but some references use 30 drops/mL.
Crosswalk and reference data
- Typical drops per mL: 20 drops ≈ 1 mL (baseline used by many calculators).
- Alternative 30 drops/mL (Tisserand-based): 30 drops ≈ 1 mL.
- 0.5–1% for sensitive skin; 1–2.5% for normal skin (per NAHA and guidelines).
- 2% commonly cited as safe for healthy adults in some sources (≈12 drops/oz for 30 mL carrier).
- Higher-risk oils have upper dermal limits; always verify specific oil safety data.
