Science
Mechanism of Action
Functioning as a sophisticated humectant, POLYQUATERNIUM-77 actively attracts and binds environmental moisture to the skin, thereby boosting hydration. Concurrently, it creates a lightweight, non-sticky barrier that significantly reduces transepidermal water loss. Beyond its direct moisturizing action, this polymer also exhibits cationic surfactant and emulsifying capabilities, facilitating the stable formation of finely dispersed oil-in-water mixtures and potentially augmenting the efficacy of co-formulated active ingredients.
