In personal care

An essential oil steam-distilled from lavender flowers, composed of a complex mix of volatile aromatic compounds, including linalool and linalyl acetate.

Why it’s used

It contributes fragrance and is popular in handmade and natural-leaning products for its scent profile and traditional association with calm.

What the evidence says

Lavender oil is a recognized contact allergen for a subset of users, particularly as it ages and oxidizes, and the SCCS has flagged fragrance allergens including its component linalool for labeling requirements. It is not considered broadly hazardous at cosmetic concentrations, but sensitization risk is real and dose-dependent.

Context

Relevant mainly in leave-on products, where prolonged skin contact increases the chance of sensitization in susceptible individuals; rinse-off exposure is lower risk. Fresh, well-stored oil carries lower allergenic potential than oxidized oil.

Rumors

  1. Causes allergic contact sensitization, especially as the oil oxidizes with age.
