Science
Mechanism of Action
Olea Europaea Fruit Extract functions by providing essential fatty acids, squalene, and vitamins A and E to deeply moisturize and nourish the skin. Its high concentration of antioxidant compounds, particularly polyphenols, actively combats free radical damage and mitigates the visible signs of aging. The extract also exhibits anti-inflammatory properties, effectively soothing irritated and sensitive skin by reducing pro-inflammatory cytokines and erythema. Furthermore, it supports skin firmness through stimulating type I collagen production and enhances hydration by promoting hyaluronic acid synthesis. The unique lipid structure within the extract can improve the bioavailability and stability of other active ingredients in a formulation, while also acting as an emollient, protective agent, and assisting in wound healing and the repair of the skin's natural lipid barrier.

The Formula
Formulation
Stability
Polyphenolic compounds within olive extracts are highly susceptible to degradation, which can compromise stability over time. Research suggests that optimal stability, particularly for oleuropein and total phenolic content, is achieved with storage at -20 °C, while storage at 25 °C is less favorable.
Synergies
- Lipid components within the extract can prolong the bioavailability and enhance the stabilization of other active ingredients in cosmetic formulations.
Conflicts
- Its polyphenolic content is prone to degradation, which must be managed during formulation and storage.
- The presence of lipophilic compounds may lead to undesirable absorption characteristics in certain applications.
- Hydrophilic UV filter compounds may not be suitable for combination in water-resistant formulations involving this extract.
Safety
Safety Profile
The CIR Expert Panel concluded that Olea Europaea (Olive) Fruit Extract is safe for use in cosmetics under current practices and concentrations, with the highest reported use in leave-on face and neck products being 0.45%. It is generally well-tolerated by all skin types, including sensitive skin, with rare adverse reactions. A patch test is recommended for individuals with potential allergies. An aqueous solution of 2.2% was found to be non-irritating to rabbit skin and eyes. The FDA also permits the use of Olea Europaea (Olive) Fruit Oil in food applications.
