What term is used for ingredients that produce the desired effects in skincare products?

The term used for ingredients that produce the desired effects in skincare products is "Active Ingredients." These are the components intentionally included in formulations to achieve specific skincare benefits, such as treating acne, reducing wrinkles, or providing hydration. Active ingredients have a direct impact on the skin, leading to observable changes and improvements in skin condition.

In contrast, inactive ingredients serve various roles but do not contribute directly to the intended effects of the product. They might include components that provide texture, stability, or preservation but lack any therapeutic benefits. Passive ingredients, while not a standard industry term, imply a lack of functional impact compared to active ingredients. Preservatives specifically refer to substances used to prevent microbial growth and prolong the shelf life of products, but do not address skin concerns directly like active ingredients do. Therefore, "Active Ingredients" is the most accurate term for those that deliver skincare results.
