What does Ascorbic Acid help with?
In Pori's database it's linked to dark spots and uneven tone, dullness, signs of aging, sun damage. How much it helps depends on how high it sits on the label: ingredients are listed from most to least, and anything past roughly the tenth spot is usually present at 1% or less.
Is Ascorbic Acid good for my skin type?

Is 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.
