How Serums Work — The Science Behind the Process
Serums are lightweight, fast-absorbing skincare formulas designed with a high concentration of selected active ingredients. Their low viscosity allows for easy spreadability and comfortable application, supporting efficient delivery across the skin’s surface.
What sets serums apart is their use of small-molecule structures and advanced delivery technologies — such as encapsulation systems, liposomes, polymer networks, and nanocarriers. These features assist in transporting ingredients where they’re needed most.
Once absorbed, each ingredient interacts with the skin in its own way.
Examples include:
• Humectants that attract moisture
• Vitamin-derived actives that support even-tone pathways
• Peptides that act as signalling molecules
• Antioxidant compounds that help reduce oxidative stress
• Ceramide-type lipids that reinforce the skin’s surface layers
By focusing on purposeful ingredient systems rather than filler materials, serums work harder within a well-designed skincare routine.
