What is a Serum?

What is a Serum?

The information about what serums are and how they’re formulated causes a lot of confusion, mainly because there’s very little consistency in how different brands describe them. The easiest way for us to describe the benefits and power of an outstanding serum is to tell you how we define and formulate our serums.

Think of serums as you would a tablet or smart phone that has maximum power and speed but is exceptionally lightweight. The best serums follow that exact concept: They contain high concentrations of proven anti-aging ingredients, especially antioxidants, because antioxidants have the ability to interrupt environmental assault when applied generously to skin. 

The other defining feature of serums is texture. Serums typically have a far lighter, thinner, fluid texture rather than the cream or lotion texture of most facial moisturizers. Despite a serum’s nearly weightless application, superior serums are brimming with the most important ingredients for restoring skin.

At Paula’s Choice Skincare, we also include hydrating ingredients in our serums, which skin also needs in abundance. Many of these hydrators work as skin-replenishing ingredients, and we round out each serum formula with a dose of skin-restoring ingredients, too.

This unique combination of ingredients makes serums a perfect addition to your skincare routine, complementing your routine with additional benefits for extra skin reinforcement and resilience, resulting in significantly younger-looking skin!

Wondering if you need a serum and a moisturizer? This article will walk you through how to add a serum to your skincare routine. You will find a selection of our Paula’s Choice Skincare serums here.
