Science
Mechanism of Action
This extract operates through a multi-faceted approach, primarily due to its rich content of flavonoids, phenolic acids, and polyphenols, which actively scavenge free radicals, thereby mitigating oxidative stress and contributing to the prevention of premature skin aging. It exerts anti-inflammatory effects by reducing the expression of inflammatory markers within keratinocytes. Furthermore, it demonstrates mild antimicrobial efficacy, specifically exhibiting antibacterial activity against Cutibacterium acnes, which aids in purifying and toning pores. This dual action helps to calm irritation, redness, and inflammation while balancing sebaceous activity, providing hydration to dry areas and reducing excess shine in oily regions.

Dusting Analysis
While generally recognized as safe, Lavandula Angustifolia Herb Extract has a critical maximum concentration threshold of 0.1% for safe cosmetic use, particularly in leave-on products. Concentrations exceeding this level are associated with a significant risk of severe allergies and rashes. This precise limit suggests that some formulations might incorporate the ingredient at sub-efficacious levels primarily for marketing or perfuming, rather than for its full range of beneficial dermatological effects.
The Formula
Formulation
Stability
Optimal stability is observed within a moderate pH range of 4.0 to 6.5. Consideration for the preservative system and the extract's vehicle is crucial. Formulators must manage potential color and odor influences, particularly in pale or delicately fragranced products. A risk of haze or precipitation exists when exposed to electrolytes or certain surfactant systems, which can vary by extract grade. To prevent organoleptic drift, packaging designed to protect against light and oxygen is essential. For optimal efficacy, it is advised to incorporate the extract into the final formulation once temperatures are below 40°C.

Safety
Safety Profile
Classified as 'Generally Recognised as Safe' (GRAS) for general use, its cosmetic application is deemed safe at concentrations between 0.015% and 0.1%. Exceeding this 0.1% maximum, especially in leave-on formulations, significantly elevates the risk of severe allergic reactions and rashes. Individuals with sensitive skin are advised to exercise caution and perform a patch test prior to full application. Direct, undiluted application to the skin is not recommended due to potential irritation.
