Is 3-O-Ethyl Ascorbic Acid comedogenic?

It has a comedogenic rating of 0 out of 5 in Pori's ingredient database, so it's unlikely to clog pores. Ratings like this come from older tests on single ingredients, and a finished product with it isn't necessarily pore-clogging. A 2006 study in the Journal of the American Academy of Dermatology found that finished products made with comedogenic ingredients were not necessarily comedogenic, so treat the number as a hint, not a verdict.
