Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Paraffinum Liquidum is a highly-refined cosmetic-grade mineral oil. It is also known as liquid paraffin.
Despite its controversial reputation, the science is pretty clear: it's one of the most well-studied and effective moisturizing ingredients out there.
As an occlusive, it forms a protective layer on the skin that locks in moisture and prevents transepidermal water loss (TEWL). This makes it especially great for compromised skin barriers.
The "it clogs your pores" myth has been around for decades; a study found that industrial-grade mineral oil may be comedogenic but cosmetic-grade mineral oil is not (these two are very, very different).
A 2017 review concluded that cosmetic use of mineral oils and waxes does not present a risk to consumers due to absorption.
Mineral oil got a bad rap from the old rabbit ear studies. When tested on actual human skin, cosmetic-grade mineral oil showed no comedogenic activity. The rating of 0 is a correction of outdated science.
Mineral oil is an inert substance with no fatty acids so there's nothing to feed Malassezia. This ingredient is fungal acne safe.
