What does the term 'anhydrous' refer to in skincare products?

The term 'anhydrous' specifically refers to products that do not contain water. In skincare formulations, anhydrous products are typically created with oils, waxes, and other emollients that provide moisture and nourishment without the addition of water. This absence of water can enhance the stability and efficacy of certain ingredients, allowing for better penetration into the skin.

Anhydrous products are beneficial for individuals seeking concentrated formulas or those who may have skin sensitivities that make them reactive to water-based products. They can also offer longer shelf life compared to products that contain water, as the risk of microbial growth is reduced when water is absent.

In contrast, options that mention water content, skin types, or enhancement with vitamins do not accurately capture the essence of what 'anhydrous' means in this context. The focus here is primarily on the lack of water, which is what makes anhydrous products distinct in the world of skincare.
