Science
Mechanism of Action
As a pentaerythrityl tetraester, this ingredient creates a protective film on the skin's surface. This barrier effectively minimizes transepidermal water loss (TEWL), locking in moisture to provide profound hydration, which is particularly advantageous for dry or dehydrated skin. Its structural properties also improve the spreadability and absorption of cosmetic formulations, enhancing the skin's texture with a silky-smooth finish.
