Which of the following is true about silicone serums?

Silicone serums are considered anhydrous products, meaning they do not contain water. This characteristic is important because it affects the serum's texture, application, and how it interacts with the skin. Anhydrous formulations often provide a protective barrier that helps to lock in moisture, making them ideal for use in treating various skin types, especially dry or combination skin.

In contrast, water-based moisturizers generally contain a significant amount of water, which impacts their consistency and absorption. High amounts of surfactants are commonly found in cleansing products, not in silicone serums, which seek to provide smooth application and a silky finish. Furthermore, while some skincare products may be derived from plant extracts, silicone serums typically rely on synthetic ingredients that provide the benefits of smooth application and enhancing the skin's overall feel without the weight of traditional creams and lotions.
