Science
Mechanism of Action
Propolis Extract acts through several key mechanisms: its rich phenolic compounds, including caffeic acid, effectively reduce inflammation and calm redness by inhibiting inflammatory pathways. As a robust antioxidant, it defends skin cells from environmental damage and oxidative stress, thereby mitigating premature aging. Its broad-spectrum antimicrobial action against bacteria, fungi, and viruses makes it beneficial for managing blemishes and soothing irritated skin. Furthermore, Propolis promotes collagen production, which enhances skin elasticity and firmness, and functions as a humectant to attract and retain moisture, strengthening the skin's natural barrier. It also stimulates new cell regeneration and accelerates the healing process.

Stability
Propolis Extract is scarcely soluble in water, but highly soluble in ethanol, with 70-75% ethanol being an effective solvent for extracting active flavonoids. While natural beeswax components are oil-soluble, specialized extraction methods employing glycerol, plant oils, or PEG-based solvents can yield water-soluble or oil-soluble extracts, making it adaptable for diverse cosmetic formulations.

Safety
Safety Profile
Propolis Extract is generally considered safe for cosmetic use, presenting as light on the skin and non-comedogenic. However, it is a known contact allergen and can induce allergic reactions, particularly in individuals with documented allergies to bee products. Patch testing is strongly recommended prior to widespread application. Due to rising allergy concerns, the CIR Expert Panel added Propolis Extract to its 2023 priorities list for an accelerated review.
