What is the Bioactivity score based on?

The Bioactivity score is based on the concentration of its acid. This score typically reflects how effective a product can be in terms of its active components, particularly how potent the acids are in delivering various skin benefits. In skincare, the concentration of acids can directly influence their ability to penetrate the skin and affect biological processes, such as exfoliation, hydration, or stimulation of collagen production. Higher concentrations of active acids generally result in a more pronounced effect on the skin, thereby increasing the Bioactivity score.

While factors like pH level, rate of absorption, and type of ingredients are important in the formulation of a product, they serve different functions and do not solely determine the Bioactivity score. For instance, pH can influence the effectiveness and safety of acid-based products, but it does not quantify the potency of the active ingredients themselves. Similarly, the rate of absorption refers to how quickly a product takes effect on the skin rather than how powerful the active ingredients are. The type of ingredients can also contribute to the overall efficacy of a formulation but does not provide a measure of how concentrated and bioactive those specific acids or actives are.
