An ampoule is a small sealed vial that contains a single application of concentrated extracts or active ingredients. These concentrated formulas are often used in professional skincare treatments to deliver potent doses of nutrients to the skin. The individual packaging helps to preserve the integrity and efficacy of the contents, protecting the extracts from light and air, which can degrade their effectiveness over time.

Understanding the role of an ampoule is essential for estheticians, as they are often included in facial treatments to enhance the outcome, especially for specific skin concerns such as hydration, brightening, or anti-aging. While masks, moisturizing creams, and serums are all important components of skincare routines, they do not encapsulate the idea of a single, highly concentrated application intended for immediate use like an ampoule does.
