Lemon-Scented Tea Tree Oil

An essential oil from Leptospermum petersonii, an Australian native related to both tea tree and manuka but a distinct species, with a citral-rich, lemon-forward profile.

How it works

Laboratory research associates its citral and citronellal content with antimicrobial activity — the reason it appears in blemish and spot formulations.

Sensitivity

Its naturally occurring citral, citronellol, linalool and geraniol are declared fragrance allergens. In targeted spot use most skin tolerates it; fragrance-reactive skin should patch test, and it is not suited to all-over application.

Pregnancy and breastfeeding

Evidence on essential oils in pregnancy is limited; the conventional advice at cosmetic levels is to check with your doctor.
