Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
You might know this ingredient as Tinosorb S or Bemotrizinol. It is a UV filter that covers both UVA and UVB rays.
This ingredient has two peak UV absorption peaks ( 310 and 340 nm) and is able to absorb both UV-A and UV-B rays. This ingredient works by preventing UV rays from reaching and damaging your skin.
On top of that - it is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.
Tinosorb S is allowed in the EU, Australia, and Asia. It is close to being approved by the FDA and we'll hopefully get this ingredient in the U.S. by late 2025.
Fun fact: Tinosorb S is the most effective UV absorber at maximum concentration (measured by SPF) permitted in the EU.
This ingredient is oil-soluble, so your oil-cleansers will take this right off at night.
Learn more about Bis-Ethylhexyloxyphenol Methoxyphenyl TriazineAlso 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.
Learn more about Butyl MethoxydibenzoylmethaneEthylhexyl Salicylate is an organic compound used to block UV rays. It primarily absorbs UVB rays but offers a small amount of UVA protection as well.
Commonly found in sunscreens, Ethylhexyl Salicylate is created from salicylic acid and 2-ethylhexanol. You might know salicylic acid as the effective acne fighter ingredient and BHA.
The ethylhexanol in this ingredient is a fatty alcohol and helps hydrate your skin, similar to oils. It is an emollient, which means it traps moisture into the skin.
According to manufacturers, Ethylhexyl Salicylate absorbs UV wavelength of 295-315 nm, with a peak absorption at 307-310 nm. UVA rays are linked to long term skin damage, such as hyperpigmentation. UVB rays emit more energy and are capable of damaging our DNA. UVB rays cause sunburn.
Learn more about Ethylhexyl SalicylateEthylhexyl Triazone is a modern chemical sunscreen that protects from UV-B radiation.
It is the most effective of existing UV-B filters, as it provides the highest level of photo-stable absorption. It protects from the entire UV-B range (280 to 320nm), with it's highest level of protection at 314nm.
Ethylhexyl Triazone is oil soluble, oderless and colorless, which mean it is able to be incorporated into a variety of different formulations.
It is not currently available within the United States due to slow changing FDA regulations. Outside of the US, it is used in formulations at concentrations up to 5%.

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.

Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.
The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Parfum can also be used to mask or cover an unpleasant scent.
The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.

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!
