Why use Kosterina olive oil-based skin care products?

Kosterina skincare is built on the same early-harvest, 500+ mg/kg polyphenol EVOO that defines our food products -- one of the most antioxidant-rich base ingredients available in beauty. We pair it with olive-derived squalane (non-comedogenic, fast-absorbing) and Lachestim, a clinically studied active that reactivates youth proteins and increases collagen synthesis. The result: deep hydration, antioxidant protection, and visibly firmer, more youthful-looking skin.
