Courtesy of TatchaEssences are the hidden gem that's missing from your skincare routine. These lightweight products are made with mostly water and packed with additional powerful ingredients to hydrate and soothe the skin right after cleansing. At first glance, adding yet another product onto your skin might seem excessive. But we'd argue that overdoing your skin with product is exactly what essences are trying to prevent. They're meant to give you a boost of hydration and prep your face to ensure the rest of your products get absorbed properly.
