Meet your skincare routine's new bestie * Works with your favorite serum * Locks in moisture * Amplifies active ingredients * Vegan and cruelty-free * Made of high-quality silicone "How do they work?" Silicone eye masks create a sealed barrier locking in hydration and maintaining the skin's water content while increasing absorption of active ingredients in serums and moisturizers. "How do I use them?" Apply your favorite eye cream or serum to clean skin. Wait a couple seconds for the eye cream or serum to get tacky. Apply the under eye patches and wait 10-20 minutes. Remove patches to reveal hydrated skin. "What are they made of?" Eye masks are made of 100% high quality silicone. To make the most of your eye masks, wash using lukewarm water and store afterwards in the metal tin.
