How does a serum differ from a moisturizer?

A serum is distinguished by its higher concentration of active ingredients compared to a moisturizer. This concentrated formula is designed to penetrate deeply into the skin to deliver specific benefits, such as anti-aging, brightening, or acne treatment. The intensive nature of serums means they are often packed with powerful compounds that can address skin concerns effectively and efficiently.

On the other hand, moisturizers primarily serve the purpose of hydrating the skin and creating a barrier to lock in moisture. They often have a thicker texture, but their formulation aims to provide a more substantial level of hydration and protection rather than targeting specific skin conditions as serums do. Therefore, the essence of the difference between the two lies in the concentration of their active ingredients and their intended use in a skincare routine.
