Linalool

Science & Benefits

Linalool is a naturally occurring terpene alcohol found in many flowers and spice plants, most notably lavender and citrus. While it provides a pleasant scent, it is a primary concern in dermatology due to its tendency to oxidize when exposed to air. Once oxidized, Linalool forms hydroperoxides, which are potent skin sensitizers and allergens. This oxidation process can cause micro-inflammation within the pore wall, leading to 'irritant-induced acne' or localized redness. It is one of the EU-regulated allergens, and its presence in high concentrations is a major risk factor for users with a compromised skin barrier.
