Petrolatum

Petrolatum at a glance

What does Petrolatum help with?

In Pori's database it's linked to a weak skin barrier, 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 Petrolatum 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 Petrolatum 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 Petrolatum?

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.
