Sodium PCA

Sodium PCA is a humectant: it draws water into the top layer of skin and holds it there. Part of skin's own natural moisturising factor. Pori's ingredient rules rate it a good fit for every skin type.

What does Sodium PCA help with?

In Pori's database it's linked to dehydration. 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 Sodium PCA 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 Sodium PCA 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 Sodium PCA?

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.
