Arginine

Arginine at a glance

Is Arginine good for my skin type?

These ratings come from the same fixed rules Pori's ingredient scanner uses, applied to a typical profile for each skin type. Your own result in the app also weighs your scan results and concerns.

Is Arginine 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.

How do I check a product with Arginine?

Scan the barcode or photograph the ingredient list with Pori's ingredient scanner (a Pro feature). It rates every ingredient for your skin type, flags fragrance, pore-clogging and irritating ingredients, and gives the product an overall match score. It's a guide to ingredients, not a diagnosis, so see a dermatologist about any reaction.
