Science & Benefits

Isocetyl Stearoyl Stearate is a large, branched synthetic ester. It is a 'Super-Clogger' (Rating 5). Its chemical structure is specifically designed to provide a rich cushion and 'waterproof' feel, which makes it incredibly difficult to wash off. This leads to rapid follicular impaction and persistent cystic acne.
