The pH of skincare products is primarily determined by the active ingredients used in the formulation. Active ingredients can significantly influence the acidity or alkalinity of a product, affecting its effectiveness and safety for skin application. Ingredients such as acids, bases, and various chemicals that serve therapeutic purposes play a crucial role in establishing the pH balance of the product. While other components like coloring agents, fragrance, and preservatives contribute to the overall formulation and sensory aspects of the product, they do not typically have a direct impact on pH levels. Coloring agents are used primarily for aesthetic purposes, fragrances add scent to enhance user experience, and preservatives are included to maintain product stability and prevent microbial growth. However, they do not influence the acid-base balance of the formulation as actively as the active ingredients do. Therefore, understanding the role of active ingredients is essential for anyone involved in skincare formulation and for ensuring products are suitable for their intended use.
