Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
CI 19140 is also known as Tartrazine. Tartrazine is a synthetic dye used in cosmetics, foods, and medicine to add a yellow color.
Tartrazine is created from petroleum and is water-soluble.
Some people may experience allergies from this dye, especially asthmatics and those with an aspirin intolerance.
Learn more about CI 19140This pigment is called Ultramarine blue lazurite. It gives a saturated blue color, but can be used to create other colors as well.
According to the manufacturer, it is usually made from kaolin, sodium sulfate, sodium carbonate, sulfur, and charcoal.
Ci 77891 is a white pigment from Titanium dioxide. It is naturally found in minerals such as rutile and ilmenite.
It's main function is to add a white color to cosmetics. It can also be mixed with other colors to create different shades.
Ci 77891 is commonly found in sunscreens due to its ability to block UV rays.
Learn more about CI 77891This ingredient comes from a fatty acid (lauric acid) and amino acid (lysine). It is used to add a silky feel to cosmetics.
According to a manufacturer, its fatty acid base leaves a silky feeling on the skin. It also has emollient properties because of this. Emollients help soften skin by preventing water from evaporating.
Lauroyl lysine is barely soluble in water.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.
Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.
It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.
This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.
This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.
In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.
Concentrations usually range from 0.1-1% in most leave-on products.

The EU typically uses CI numbers for colorants when applicable, such as CI 77489. In the US, iron oxides are regulated as color additives and "iron oxides" is the most commonly used name in US cosmetic practice.
A 2021 paper looked at skincare formulations containing iron oxides and found that they reduced transmission of blue light when measured optically. In simple terms, the pigment particles helped block or scatter part of the visible light spectrum in lab testing and the authors suggest this could translate into better protection against blue-light-related skin effects.
There is also clinical and experimental research showing that tinted products containing iron oxides can reduce visible light-induced pigmentation:
Please note, whether a product reduces visible or blue light depends on things like:
In the EU's CosIng database, iron oxides are only listed as a colorant. CosIng groups ingredients by their main cosmetic role, such as colorant, preservative, or UV filter.
Though studies say iron oxides can "attenuate blue light", they're describing an optical property and not an officially recognized cosmetic function.
So CosIng isn’t contradicting the research. It’s just classifying iron oxides by what they officially are: pigments that add color.
