What is the difference between a face oil and a face serum?

Serums are lightweight, concentrated liquids formulated to help correct skin concerns such as hyperpigmentation and dullness. They are typically water-based and contain other moisturizing ingredients like hyaluronic acid. Facial oils are oil-based liquids formulas and typically formulated with non-comedogenic botanical oils and includes plant extracts and antioxidants, which won’t cause breakouts or clogged pores. Face oils are rich, emollient formulas that helps moisturize and soften the skin and nourish the skin barrier while leaving a youthful glow.
