What is a key benefit of using serums in skincare?

Using serums in skincare is highly valued for their ability to deliver a concentrated dose of active ingredients directly to the skin. This characteristic allows serums to address specific skin concerns effectively, such as hyperpigmentation, fine lines, and blemishes. The formulation of serums typically includes smaller molecules that can penetrate deeply into the skin, making them more efficient in providing targeted treatment compared to other products like creams or lotions.

While providing additional moisture is a common characteristic of many skincare products, serums primarily focus on their active ingredients rather than hydration alone. They can complement moisturizers rather than replace them, as they usually lack the occlusive properties necessary to lock in moisture effectively. Additionally, while certain serums may help enhance makeup longevity, this is not their primary function; they are primarily therapeutic treatments for the skin. Thus, the key benefit of serums lies in their capacity to furnish the skin with potent active ingredients that can lead to improved skin health and appearance.
