Understanding Serums: What They Are and Why They Work
The Science Behind Serums
Serums differ fundamentally from moisturisers and cleansers. Specifically, they contain smaller molecules that penetrate deeper into the skin. Furthermore, serums feature higher concentrations of active ingredients. marieclaire.co
Consequently, serums deliver targeted results more efficiently. Additionally, they layer seamlessly under moisturisers and sunscreen. glamourmagazine.co
