Faster and lighter are qualities we look for in many things, including skincare. Serums are light, fast-absorbing liquids used as an alternative or in addition to creams and lotions.
What makes a serum different?
The biggest difference between a serum and a cream or lotion is often what the formulation leaves out. Many serums contain fewer occlusive moisturising ingredients, like petrolatum or mineral oil, and fewer thickening agents. Many are water-based, although formulations vary.
Serums may contain concentrated active ingredients, including antioxidants, peptides and skin-brightening ingredients such as kojic acid and arbutin. The right choice depends on your skin and the specific formulation. A serum is not a necessary step for everyone.
Serum costs, serum benefits
Concentrated active ingredients can make serums one of the more expensive products in a skincare line. Follow the product directions: a small amount is often enough, so a container may last several months.
Lightweight formulations can layer comfortably under moisturiser. Creams help lock moisture into the skin, while serums can target particular concerns. Absorption and effectiveness depend on the ingredients and formulation, not just the texture. Ask your dermatologist what your skin actually needs.
