Ingredients Explained
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 The rating of 0 is a correction of outdated science.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.

In cosmetics, it plays many roles:
One thing worth noting: a controlled study found this ingredient applied under occlusion to acne-prone subjects increased microcomedones. Just keep in mind this was under occlusive conditions and don't reflect how most products are used day-to-day.
For most people, this is a well-tolerated and lightweight ingredient.
This ingredient may not be fungal acne safe because it is an ester of palmitic acid, a C16 fatty acid that falls within the C11-24 range that Malassezia can metabolize.

This is a color pigment that has a metallic and golden hue.
In the EU, this ingredient is permitted for use as a cosmetic colorant. However, the US and FDA does not list it as an approved cosmetic color additive. This affects how products that contain gold are labeled or formulated in the US market.
As a result, CI 77480 is mainly relevant in the EU regulatory context as a pigment and not an active / treatment ingredient.
