Creams and serums are two essential products in any skin care routine. Creams are usually thicker and heavier in consistency, and are used to moisturize and nourish the skin. They are best applied after cleansing and toning, and can be used morning and night for maximum benefit. Serums, on the other hand, are lightweight and have a more liquid consistency. They are designed to penetrate deep into the skin, delivering targeted ingredients to address specific concerns such as fine lines, uneven skin tone and dullness. Serums are usually applied after cleansing and toning, but before moisturizing, and can be used morning or night depending on the specific product. Both creams and serums can be an effective part of any skin care routine, and choosing the right one for your skin type and concerns is key to achieving healthy, glowing skin.
