The DEEP HYDRO FIRST ESSENCE by INNABELLO is typically used as a hydrating and nourishing essence designed to provide deep moisture to the skin. Essences are lightweight formulations that are usually applied after cleansing and toning but before heavier treatments like serums and creams. They aim to prep the skin to better absorb subsequent products and often contain a concentrated blend of active ingredients to enhance skin texture, hydration, and overall health.
