What is the role of an active ingredient in a product?

An active ingredient in a product plays a crucial role in delivering therapeutic effects. These ingredients are specifically formulated to target certain skin concerns or conditions, such as acne, hyperpigmentation, or aging. They are the components responsible for the product's primary function, providing benefits that can lead to visible improvements in skin health and appearance.

For instance, active ingredients like retinoids encourage cell turnover, hyaluronic acid hydrates the skin, and salicylic acid helps in exfoliating and clearing pores. This direct impact on skin physiology is what distinguishes active ingredients from other components in a formulation. While other aspects of a product, such as scent, texture, and preservation, are important for user experience and product stability, they do not carry the therapeutic intention that defines the role of active ingredients.
