Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Also known as Avobenzone, this ingredient is a chemical sunscreen filter that provides protection in the UV-A range.
Avobenzone is globally approved and is the most commonly used UV-A filter in the world.
Studies have found that avobenzone becomes ineffective when exposed to UV light (it is not photostable; meaning that it breaks down in sunlight). Because of this, formulations that include avobenzone will usually contain stabilizers such as octocrylene.
However, some modern formulations (looking at you, EU!) are able to stabilize avobenzone by coating the molecules.
Avobenzone does not protect against the UV-B range, so it's important to check that the sunscreen you're using contains other UV filters that do!
The highest concentration of avobenzone permitted is 3% in the US, and 5% in the EU.

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

It is a synthetically created solvent and emollient often used to replace silicones or mineral oil. As an emollient, C15-19 Alkane helps soften and soothe the skin. Emollients create a barrier to trap moisture inside.
C15-19 Alkane is often used with mineral UV filters such as titanium dioxidide and zinc oxide. It helps these UV filter ingredients be more spreadable.
C15-19 Alkane is biodegradable.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

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!
