Phytosteryl Macadamiate

Phytosteryl Macadamiate is an ester made by combining phytosterols (the plant version of cholesterol) with fatty acids from macadamia seed oil.

It's a botanical copycat of the cholesteryl esters found in your skin's surface lipids and mimics how your skin's own barrier lipids organize.

Research on phytosterols show they can help with skin barrier recovery and protect skin against UV-induced damage when combined with ceramides.

The fatty acid portion of this ingredient is mainly oleic acid and palmitoleic acid, two potential Malassezia triggers. Be sure to patch test if you're unsure.
