Science
Mechanism of Action
This ingredient functions by combating oxidative stress through the potent scavenging of various free radicals, such as DPPH, nitric oxide, superoxide anion, and hydroxyl radicals. Its antimicrobial, antibacterial, and antifungal properties are effective against a spectrum of microorganisms, including those associated with acne. Additionally, it provides anti-inflammatory effects to soothe irritation, an astringent action to refine pores and regulate sebum, and contributes to the skin's overall nourishment, hydration, and wound healing.

Stability
The essential oil form of Laurus Nobilis Leaf is highly concentrated and requires precise dilution, generally up to 0.1%, to ensure safe topical application and mitigate skin irritation. Extracts containing key compounds like polyphenols can be obtained effectively using various solvents, including both water and ethanol, suggesting diverse solubility profiles for its active components.
Safety
Safety Profile
Laurus Nobilis Leaf, particularly in its essential oil and extract forms, is associated with a high risk of skin irritation and is an established contact allergen in humans, as reported by the European Commission's SCCS. Irritation has been observed at concentrations as low as 1%. It is strongly advised that pregnant women, children, and individuals with sensitive skin avoid this ingredient, and patch testing is considered essential prior to use. While generally recognized as safe (GRAS) by the U.S. FDA as a food additive, EWG flags high concerns for allergies, immunotoxicity, and use restrictions, especially in inhalable forms. Allergic contact dermatitis from laurel essential oil has been documented in rare cases.
