Comedogenic Rating

Zinc Stearate has a comedogenic rating of 2. It has a low likelihood of clogging pores but may not suit all skin types.

Safety

Typically low irritation, but very acne-prone users may notice congestion with heavy or frequent use. Avoid inhalation of loose powders; for external use only.

Is Zinc Stearate a Good Ingredient?
