Ingredient review
P-Cresyl Octanoate
INCI: P-CRESYL OCTANOATE
A synthetic ester that adds a subtle scent and light conditioning feel, but offers no active skincare benefits.
In plain English
P-Cresyl Octanoate is a man-made ingredient that smells pleasant and helps other ingredients mix together smoothly. It is not a star active like vitamin C or hyaluronic acid—it's more of a supporting player that makes a product feel and smell nicer. Because it is used in tiny amounts, it rarely causes problems, but it does not improve your skin's health on its own.
