Ingredients Side-by-side
Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
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!
Learn more about WaterGlycerin is already naturally found in your skin. It helps moisturize and protect your skin.
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.
Learn more about GlycerinAlso 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.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Polyglutamic Acid is made up many glutamic acids chained together. It is created from bacterial fermentation.
Polyglutamic Acid is an effective skin hydrator and may help speed up wound healing. As a humectant, it draws and holds water to the skin. This ingredient is often compared to hyaluronic acid or glycerin. Similarly to hyaluronic acid, it can vary in molecular weights. This means polyglutamic acid is capable of bringing hydration to lower levels of the skin.
Polyglutamic Acid is found in the Japanese food, natto. It is also being used in cancer treatment studies.
Learn more about Polyglutamic AcidSodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.
Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
Sodium Benzoate is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.

I bought it as a moisturizing and priming sunscreen for colder months, but even in winter it would make my skin so sticky and oily after a few hours. Moreover, during application the texture feels a little bit grainy even when shaken well before use.
If you use a toner and a serum underneath, get ready for pilling when applying makeup. I tried it with a lot of different serums and can tell that pilling is unavoidable unless you use it on bare skin. Then, at least for me, it absorbs almost completely (I have combination skin). So, with this sunscreen, you gotta choose whether you want to use a serum underneath or some makeup on top, as both are not an option.
I give it two stars because it is indeed hydrating and moisturizing, so I can appreciate that on a very dry winter day when I'm not using any other products. But exactly because of this I'm having a lot of trouble finishing it.
