Science
Mechanism of Action
Within skincare formulations, Potassium Acetate functions primarily as a humectant, drawing water molecules from the environment into the skin's outermost layer, the stratum corneum, thereby enhancing hydration. Concurrently, it acts as an effective buffering agent, stabilizing the product's pH within a targeted range, which is critical for optimizing ingredient efficacy and preventing potential skin irritation.
