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 WaterEthylhexyl 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%.
Learn more about Ethylhexyl TriazoneDiethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UV-A absorber. It is formulated for high UVA protection (320-400 nm).
DHHB is well-liked for:
DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%. Unfortunately, it has not been approved for use in the US or Canada due to slow regulatory processes.
This ingredient is soluble in oils, fats, and lipids.
Learn more about Diethylamino Hydroxybenzoyl Hexyl BenzoateEcamsule is a UV-A absorber (290–400 nm) patented by L'Oreal. It is derived from benzylidene camphor, making it highly photostable.
Ecamsule is able to prevent UV from reaching the skin. It absorbs UV and releases it as thermal energy.
It does this by:
The pH of ecamsule needs to be neutralized due to it being an acid. Triethanolamine is a pH adjusting ingredient often used with ecamsule.
This sunscreen ingredient is approved for use in the EU, Canada, and Asia. In the US, you will only find this ingredient in select L'Oreal products.
Learn more about Terephthalylidene Dicamphor Sulfonic AcidTromethamine helps balance the pH and improve the texture of a product. It is synthetically created.
As an emulsifier, Tromethamine prevents oil and water ingredients from separating. This helps stabilize the product and elongate a product's shelf life. Tromethamine also makes a product thicker.
Tromethamine helps balance the pH level of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.
Oral Tromethanmine is an anti-inflammatory drug but plays the role of masking, adding fragrance, and/or balancing pH in skincare.

It is be used to thicken water-based products and create a gel-texture with a velvet feel.
One manufacturer claims this ingredient to have a pH range of 2-8 and to be biodegradable.
Learn more about Polyacrylate Crosspolymer-6Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

This sunscreen is so light and easy to spread, I love it! The ingredients look really good too, there's no alcohol, fragrance, or oil, and it doesn't have any ingredients that trigger fungal acne.
It also makes my skin look dewy and it lasts for a long time.
Edit - I've been using it for two months now and I've already bought two more bottles because this is definitely my favorite sunscreen. The Show more

People are sleeping on this! They need to invest more money in promoting this product because it’s so good. Trust me, I’ve been desperately hunting for a good sunscreen for my acne-prone, oily skin, and that search has led me here.
It’s not fungal acne-safe, but I didn’t break out. Plus, they use modern UV filters, which is a big plus for me. They weren’t lying about it being lightweight—it Show more
The texture and finish is beautiful, very lightweight and radiant natural finish. However, this gave me irritation within 5mins of application - stinging and redness. I have highly sensitive skin and i think the citrus extract does not work well with my skin.
