What is the primary purpose of using serums in skincare?

The primary purpose of using serums in skincare is to deliver concentrated active ingredients deep into the skin. Serums are typically formulated with a high concentration of active compounds that target specific skin concerns such as aging, hyperpigmentation, or dehydration. Due to their lightweight consistency and smaller molecular structure compared to creams and lotions, serums can penetrate the skin more effectively.

This ability to penetrate deeper allows serums to provide more significant benefits compared to other skincare products, which may primarily serve to moisturize or protect the skin's surface. Therefore, when aiming for noticeable results and addressing specific skin issues, incorporating a serum into a skincare routine can be extremely beneficial.

While other choices address important aspects of skincare, such as protection, cleansing, and soothing, they do not capture the primary function of serums, which is their role in delivering potent ingredients for treatment and improvement of skin conditions.
