Ingredients Side-by-side
Cyclopentasiloxane is a silicone used to improve texture and trap moisture. An easier name for this is D5.
Dimethicone/Vinyl Dimethicone Crosspolymer is a silicone used to improve the texture of products and absorb oil. It does not get absorbed into the skin.
2 Concerns
Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
2 Concerns
Ethylhexyl Methoxycinnamate is an organic compound that provides UVB protection. It often goes by the more common name of octinoxate. It is created from methoxycinnamic acid and 2-ethylhexanol.
2 Concerns
Octocrylene protects skin from sun damage. It absorbs UV-B with peak absorption of 304 nm. It is a common sunscreen ingredient and often paired with avobenzone, a UVA filter. This is because octocrylene stabilizes other sunscreen ingredients by protecting them from degradation when exposed to sunlight. Octocrylene is a photostable ingredient and loses about 10% of SPF in 95 minutes.
Phenoxyethanol 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.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
2 Concerns
Also known as Avobenzone, this ingredient is a chemical sunscreen filter that provides protection in the UV-A range.
You might know this ingredient as Tinosorb S or Bemotrizinol. It is a UV filter that covers both UVA and UVB rays.
Caprylic/Capric Triglyceride is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.
Laminaria Ochroleuca Extract is a type of kelp. It helps sooth and hydrate the skin. By nourishing the skin's barrier, it may also help relieve irritation.
Bisabolol is pimarily used to add fragrance to a product. However, it is also famous for helping soothe skin.
Aroma refers to an ingredient, or mixture of ingredients, that impart or mask a flavor.
Maltodextrin is a polysaccharide. It is derived from starch such as rice, corn, wheat, or potato starch.
2 Concerns
Paraffinum Liquidum is also known as liquid paraffin. It is a type of highly refined mineral oil.
C12-15 Alkyl Benzoate is made up of Benzoic Acid and long chain alcohols. It has a low molecular weight.

Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.
Silica is present naturally within the skin during collagen production and when reducing inflammation.
Learn more about SilicaEthylhexyl Methoxycinnamate is an organic compound that provides UVB protection. It often goes by the more common name of octinoxate. It is created from methoxycinnamic acid and 2-ethylhexanol.
Ethylhexyl Methoxycinnamate absorbs UVB rays with wavelengths between 280-320 nm. UV absorbers protect your skin by using chemical reactions to convert UV rays into heat and energy.
UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA, causing sunburns and are thought to be linked to skin cancer.
The state of Hawaii has banned sunscreens containing octinoxate due to its potential impact on coral reefs. More research is needed to bridge gaps in this research. The European Union allows higher levels of octinoxate in sunscreens than the US and Australia.
Ethylhexyl Methoxycinnamate is oil soluble. It is not stable and may lose efficacy when exposed to sunlight.

It is a common sunscreen ingredient and often paired with avobenzone, a UVA filter. This is because octocrylene stabilizes other sunscreen ingredients by protecting them from degradation when exposed to sunlight. Octocrylene is a photostable ingredient and loses about 10% of SPF in 95 minutes.
Octocrylene also acts as an emollient, meaning it helps skin retain moisture and softens skin. It is oil-soluble and hydrophobic, enhancing water-resistant properties in a product.
Those who are using ketoprofen, a topical anti-inflammatory drug, may experience an allergic reaction when using octocrylene. It is best to speak with a healthcare professional about using sunscreens with octocrylene.
The EU allows a maximum of these concentrations:

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
You might know this ingredient as Tinosorb S or Bemotrizinol. It is a UV filter that covers both UVA and UVB rays.
Bemotrizinol has two peak UV absorption peaks ( 310 and 340 nm) and is able to absorb both UV-A and UV-B rays. Skin exposed to UV causes free-radical molecules to form. This ingredient works by preventing the UV from reaching your skin.
It is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.
Bemotrizinol is not approved in the US but is allowed in the EU, Australia, and Asia.
In fact, it is the most effective UV absorber at maximum concentration (measured by SPF) permitted by in the EU.
It is oil-soluble.

Bisabolol comes from German chamomile essential oil. Synthetic Bisabolol has been shown to be less effective.
Bisabolol helps soothe skin. It does this by blocking the inflammatory signals, helping to reduce your body's reaction to irritation.
Bisabolol also interferes with the process of hyperpigmentation. This can help with reducing dark spots and uneven tone.
Bisabolol is an antioxidant. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells. By fighting these free-radicals, Bisabolol may slow down signs of aging.
Studies have shown Bisabolol to have antimicrobial properties and may be a fungicide. These properties help preserve a product's shelf life.
Bisabolol also helps the absorption of other ingredients.

This is the only sunscreen so far that doesn't break me out. I also love the matte, powdery finish it leaves on my skin. Easy to reapply too. I also like the scent, doesn't linger too much though so it's perfect.
