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.
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.
Learn more about DimethiconePhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Polymethylsilsesquioxane is a silicone used as a film forming agent.
When applied to the skin, this ingredient creates an invisible film on the surface. This film still allows oxygen to pass through, but prevents moisture from escaping. This can help condition and hydrate the skin. It also leaves a silky feel when applied.
Polymethylsilsesquioxane has not been shown to clog pores. It has been deemed safe to use up to 55%, but most cosmetics use much less.
If you have concerns about using this ingredient, we recommend speaking with a professional.

It sits on the skin’s surface and primarily reflects and scatters UV light and also absorbs some of it.
This makes the line between “mineral” and “chemical” sunscreens a bit blurry, but in skincare labeling, Titanium Dioxide and Zinc Oxide are the two ingredients officially classified as mineral filters.
Because it’s non-irritating, Titanium Dioxide is often recommended for sensitive or acne-prone skin.
Thanks to modern production methods, nano-scale or fine-grade Titanium Dioxide is now widely used in cosmetics to reduce white cast and improve texture.
Despite its small particle size, studies show that Titanium Dioxide, even in nanoparticle form, is not absorbed into the skin.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
