- Derived from plants traditionally associated with calming and relaxation properties
- Part of essential oil blends used in aromatherapy applications
Potential concerns
- May cause skin irritation or allergic contact dermatitis in sensitive individuals
- Can oxidize when exposed to air, potentially creating irritant byproducts
- Lavender extracts containing linalool have estrogenic and antiandrogenic properties — topical application near the breast should be avoided
Science: Lavender, which contains linalool as a major compound, is recognized as generally safe (GRAS) by the FDA. However, limited peer-reviewed safety data exists specifically for linalool in topical skincare formulations, and individual sensitivity varies. Caution is warranted for prolonged or concentrated use, particularly in sensitive populations.
