Science
Mechanism of Action
This extract exerts its beneficial actions through a rich composition of flavonoids, phenolic acids, and polyphenols, functioning as a robust antioxidant to neutralize free radicals and mitigate premature aging. Its inherent properties provide calming and soothing effects, effectively reducing redness and inflammation. Additionally, it offers mild antimicrobial activity against common skin microorganisms such as *Staphylococcus aureus* and *Staphylococcus epidermidis*, contributes to sebum regulation for a mattifying effect, and acts as a skin conditioning agent by enhancing skin tolerance, elasticity, and hydration, thereby strengthening the skin barrier and alleviating tightness.

Formulation
Stability
The extract's pH stability is matrix-dependent, with extreme pH potentially altering its color or odor. It is sensitive to prolonged thermal stress, necessitating controlled-temperature addition. Variability in light and oxygen stability may lead to organoleptic drift, suggesting the use of barrier packaging and compatible antioxidants.
Conflicts
- Compatibility with preservatives and chelants should be carefully assessed.
- Risk of haze or precipitation, particularly with electrolytes or certain polymers.
- Performance and stability are influenced by the carrier system (e.g., glycols, alcohols, glycerin, water).
Safety
Safety Profile
LAVANDULA ANGUSTIFOLIA FLOWER/LEAF/STEM EXTRACT is considered safe for cosmetic use at concentrations between 0.015% and 0.1%. Concentrations exceeding 0.1%, especially in leave-on formulations, may induce severe allergies and rashes. A patch test is strongly recommended prior to use, particularly for individuals with sensitive skin, who may experience allergic reactions due to sensitivity to lavender or other Lamiaceae family plants. Caution is advised for very sensitive or reactive skin, delicate areas, and high-exposure leave-on products. The ingredient is classified as 'Generally Recognised as Safe' (GRAS) and by the SCCS, subject to potential restrictions in Annex III of the EC Cosmetics Regulation.
