Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
CI 77163 is the color-index name for Bismuth Oxychloride, a lab-made white powder that acts as a pearl pigment.
It's what gives a lot of pressed powders, eyeshadows, highlighteres, and mineral foundations that soft pearly glow.
Due to its structure as flat, plate-like crystals that stack like tiles, it feels silky and sticks to skin well. This also makes it very chemically stable and insoluble under normal skin conditions (this just means it sits on top of skin rather than going into it).
It has an interesting quirk: it slowly goes gray in sunlight and the graying is partly reversible in the dark.
At this time, there's no legal cap on how much a brand can use. Both the FDA and the EU permit it without restriction so real-world concentration levels come down to formulation:
Allergy risk is low as well since it's insoluble and doesn't release free metal ions into skin. True allergic contact dermatitis to it is rare enough that there's very little published cases.
However, mineral makeup users do report itching or stinging. The leading explanation for this is irritation from those stiff platelet crystals rubbing on skin (also more likely with heavy, high-percentage loose mineral powders) rather than an immune reaction.
This ingredient shows up on a lot of "pore-clogging" lists but there's no real evidence behind that. It doesn't even have a comedogenic rating from an actual study; the numbers you'll find online come from blogs citing other blogs.
Some people still find it breaks them out. So if that's you, definitely trust your skin.

Learn more about CI 77891Kaolin is a clay. It is used for oil control and to help minimize pores. Like other clays, kaolin has the ability to absorb excess sebum or oil. This can help clean out pores and mattify the skin.
Some types of kaolin may have exfoliating properties. When water is added to kaolin, it becomes a paste with small abrasive particles.
Most kaolin is a white color, but may be pink/orange/red depending on where it comes from.
The name 'kaolin' comes from a Chinese village named 'Gaoling'. Kaolin clay comes from rocks rich in kaolinite. Kaolinite, the mineral, has a silicate layered structure. Kaolinite is formed from chemical weathering of aluminum siilicate minerals.
Besides skincare, kaolin is commonly used to make glossy paper, in ceramics, toothpaste, and as medicine to soothe stomach issues.
