Science
Mechanism of Action
This extract is rich in polyphenols and flavonoids, powerful antioxidants that neutralize free radicals to protect skin from environmental damage and premature aging. Its anti-inflammatory properties calm irritation and support the skin's natural healing processes. Furthermore, it deeply hydrates, reinforces the skin's barrier function, and stimulates cell renewal. Key active compound Oleuropein contributes to reducing cellular damage, boosting collagen production, and promoting re-epithelialization for improved skin recovery. It also offers potential photoprotective benefits against UVA-induced damage.

Stability
The extract itself typically presents a pH between 3.0 and 5.5. For optimal stability and extraction yield of its key active, oleuropein, an acidic pH around 3.0 is ideal, with stability decreasing as pH increases. High temperatures, especially when combined with either acidic or alkaline pH, can lead to the degradation of oleuropein.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed its safety for use in cosmetics at current concentrations, with the highest reported use in a leave-on formulation being 2% in suntan preparations. It is generally considered non-irritating; human dermal irritation tests showed no irritation even at 100% concentration. However, individuals with known allergies to olives or their derivatives should perform a patch test. It holds a Generally Recognized As Safe (GRAS) status by the FDA for food use.
