The primary function of a serum in skincare is to target specific skin issues with concentrated treatments. Serums are formulated with high concentrations of active ingredients that are designed to penetrate deeper into the skin compared to other products, like creams or lotions. This makes them particularly effective for addressing specific concerns such as pigmentation, fine lines, uneven texture, and acne.

The lightweight nature of serums allows them to be applied after cleansing and toning, but before moisturizing, helping to deliver potent ingredients directly to the skin. Because of this targeted approach, serums can be customized to meet individual needs, making them a vital component in a personalized skincare routine.

Hydration, barrier protection, and gentle exfoliation are important as well, but these functions are typically associated with moisturizers, treatments, and exfoliating products rather than serums, which specifically excel at delivering concentrated solutions for particular skin concerns.
