Lavender Oil
An essential oil from lavender flowers used in skincare for fragrance and potential calming properties. It is well tolerated in diluted concentrations within formulations, though undiluted lavender oil can irritate skin. People sensitive to essential oils or with documented lavender allergies may choose to avoid products with high concentrations.
Lavender is both a cure-all and simultaneously toxic or allergen-triggering in any dose.
