Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Dimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane.
What it does:
Dimethicone comes in different viscosities:
Depending on the viscosity, dimethicone has different properties.
Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.
This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.
Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.

Emollients create a thin barrier that traps moisture underneath, hydrating the skin.
This ingredient may not be fungal-acne safe.

It is a white powder that can be used to add bulk and color to products by binding to oil ingredients.
Pentaerythrityl Tetraisostearate is derived from isostearic acid. It is an emollient and emulsifier.
The highest concentration of this ingredient is found in lipsticks.
This ingredient is minimally water soluble and may not be Malassezia folliculitis, or fungal-acne safe.

Some Baby powders are made by combining talc with corn starch. The word "talc" comes from Latin and originates from Arabic. Talc is a mineral commonly found throughout the world.
If you have any concerns about using talc, we recommend checking out the FDA's official page.

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.
