Lavender Oil
Lavandula Angustifolia (Lavender) Oil · Lavandula Angustifolia Herb Oil
A popular scent oil. Lab tests found hormone-like activity, and air turns one of its scent chemicals into a common allergen.
What it does
It’s one of the most-used essential oils in skincare. A 2007 report linked lavender and tea tree oil on skin to breast growth in three young boys, and lab tests found hormone-like activity in both, so it’s not advised in pregnancy or before puberty. Air also turns linalool, one of its scent chemicals, into a common allergen.

The evidence, graded
expert consensusTopical lavender oil (Lavandula angustifolia) carries estrogenic and antiandrogenic activity in human cell lines, and repeated exposure was the probable cause of prepubertal gynecomastia in a published case series. Nobody has studied it in pregnancy; Drop extends the same caution there rather than treating an untested ingredient as a cleared one.Henley 2007 · New England Journal of Medicine ↗ moderateLinalool, one of the two main scent chemicals in lavender oil, is barely allergenic when pure. Once air oxidizes it, it becomes a common allergen. In a six-country study, 6.9% of 2,900 people patch-tested for dermatitis reacted to oxidized linalool.Bråred 2012 · Contact dermatitis ↗ Graded per the methodology: strong · moderate · emerging · expert consensus.
