Science
Mechanism of Action
This extract functions by blocking the inflammation pathway, thereby alleviating redness and discomfort in the skin. It imparts soothing and purifying qualities and demonstrates an ability to balance the skin's oil production, delivering hydration to dry skin while reducing shine for oily complexions. Its natural antioxidant compounds actively combat free radicals, a primary contributor to premature skin aging. Furthermore, it acts as a skin conditioning agent, helping to restore and improve skin tolerance against external aggressors and prevent dehydration.

Key findings
- 01 In vitro studies revealed that ethanolic flower extract was effective against various bacteria, with minimum inhibitory concentrations (MIC) ranging from 0.1% to 1.5% and minimum bactericidal concentrations (MBC) from 0.2% to 2.5%.
- 02 The ethanolic flower extract also exhibited strong antifungal effects in vitro, showing MICs between 0.05% and 2.5% and minimum fungicidal concentrations (MFC) from 0.1% to 5.0%.
- 03 Conversely, ethanolic leaf extract demonstrated weaker antibacterial effects in vitro, requiring higher concentrations (MICs of 1.25-10.0%, MBCs of 2.5-12.5%).

Dusting Analysis
There is no direct evidence to suggest this specific extract is commonly 'dusted' or used below its effective concentrations in cosmetic formulations. Clinical efficacy data provides specific in vitro ranges for antimicrobial activity.
The Formula
Formulation
Stability
The pH stability of this extract is matrix-dependent; extreme pH conditions may lead to changes in color or odor. It is sensitive to prolonged thermal stress, thus necessitating controlled-temperature addition during manufacturing. Stability concerning light and oxygen is variable, potentially leading to organoleptic drift, and the use of barrier packaging may aid in preservation.
Conflicts
- Preservatives and chelants (potential for compatibility issues)
- Electrolytes (risk of haze or precipitation)
- Specific polymers (risk of haze or precipitation)
Safety
Safety Profile
The substance is approved for cosmetic use, subject to restrictions under Annex III of the EC Cosmetics Regulation, following assessment by the Scientific Committee on Consumer Safety (SCCS). These restrictions may pertain to purity criteria, maximum concentration, or specific product categories. While not typically classified as an allergen, as a botanical extract, it may contain potentially sensitizing components or odor-active compounds that can be declarable fragrance allergens. Caution is advised for very sensitive or reactive skin, application in delicate areas, and inclusion in high-exposure leave-on products. Avoidance on compromised skin is recommended if risk assessment indicates concerns. Notably, for Lavandula Angustifolia extract, concentrations exceeding 0.1% in leave-on products have been linked to severe allergies and rashes in individuals with sensitive skin, suggesting a cautionary approach to related species.

Verdict
This versatile botanical extract is valuable for its broad calming, purifying, and antioxidant benefits across all skin types; however, its potential for sensitization in specific contexts necessitates careful formulation and usage, particularly in sensitive skin or at higher concentrations.
