The primary benefit of using a serum in skincare is to provide hydration and target specific concerns. Serums are formulated with a higher concentration of active ingredients compared to regular moisturizers. This allows them to penetrate deeper into the skin, delivering potent ingredients that can address a variety of skincare issues such as fine lines, uneven skin tone, dullness, and acne.

Because serums are lightweight and designed to be absorbed quickly, they sit well beneath other products, enhancing overall effectiveness. This targeted approach means that individuals can choose serums based on their specific needs, whether they are looking for anti-aging benefits, increased luminosity, or improved texture.

While other options address various aspects of skincare, they do not encapsulate the core purpose of serums as effectively. For instance, cleaning the skin is typically the role of a cleanser, serving as a base for makeup pertains more to primers, and protecting against sun damage involves sunscreens rather than serums. Thus, the focus on hydration and specific concern targeting is what distinctly defines the function of serums in a skincare routine.
