True lavender versus lavandin
There is a real quality difference. Lavandula angustifolia (true lavender, alpine) is gentler, lower in camphor, and considered safe on skin at cosmetic concentrations including for pregnancy. Lavandula intermedia (lavandin) is a hybrid grown at lower altitudes - higher yield, sharper camphor note, less skin-friendly. Read the binomial on any lavender product you buy. Our cosmetic lavender is angustifolia.
Why it appears in body oils rather than face products
Lavender essential oil contains linalool, an allergen that must be declared on cosmetic labels above 0.001% in leave-on products. At the diluted concentrations we use in body oils and scrubs (rinse-off), the allergen exposure is well below clinical relevance for most people, but some sensitive faces react. That is why our lavender shows up in body-focused products rather than face creams.
