Phytosphingosine phosphate is a large mix of esters derived from phytosphingosine and phosphoric acid. The complex lipids that result have a skin-smoothing and hydration-boosting effect. This ingredient may be plant-derived or synthetic.
Topically, phytosphingosine phosphate plays a role in signaling skin to strengthen its surface and work with naturally-occurring substances in skin to promote a firmer, smoother look and feel.
