Propolis

Propolis contains flavonoids, phenolic acids, terpenoids, and aromatic esters, whose composition varies geographically but whose skincare effects are well-studied. The substance inhibits the growth of Staphylococcus aureus, Cutibacterium acnes, and various fungal organisms, making it effective against acne, infections, and unbalanced skin. The flavonoid-rich compounds, especially artepillin C and CAPE, have anti-inflammatory effects by inhibiting the NF-κB signaling pathway and reducing the production of pro-inflammatory cytokines. Its antioxidant capacity is high, protecting against oxidative stress and UV-induced photoaging. The ingredient also supports wound healing and cell repair by stimulating fibroblast activity. In Korean skincare, it is used in serums, toners, and essences for acne-prone and stressed skin. Regular application results in noticeably clearer, calmer, and more balanced skin with visibly reduced breakouts and improved barrier function. The fact that bee colonies have used this mixture to stay disease-free for millennia makes the ingredient one of nature's most sophisticated antibacterial systems.
