Science
Mechanism of Action
This ingredient operates by signaling the skin to strengthen its surface and works in conjunction with naturally occurring substances to promote a more resilient, smooth appearance and feel. As a bioactive sphingolipid molecule, specifically Phytosphingosine-1-phosphate (PhS1P), it demonstrates high-affinity binding to the S1P(4)/Edg-6 receptor, indicating its active role in cellular signaling pathways. Furthermore, PhS1P can amplify the activity of epidermal growth factor (EGF) both in vitro and in vivo, leading to increased dermal thickness and density by downregulating MMP1 and stimulating collagen synthesis.
