Cyclomethicone is a class of silicones used to improve the texture of products.

Their cyclic or circular structure decreases stability. This causes quick evaporation when applied to skin. Cyclomethicones are often used as a carrier for other ingredients. Once it evaporates, it leaves a silky barrier on the skin.

The most popular types of cyclomethicones include D5 and D6.

Zinc Oxide is a mineral broad-spectrum UV filter; it is the broadest UVA and UVB reflector approved by the FDA. While it is most commonly man-made for cosmetics, it can naturally occur in zincite, a rare mineral.

Today, traditional and nano-sized zinc oxide can be found in beauty products. Nano-sized zinc oxide can enhance a product's UV protection. While it is not believed to have a negative effect on skin, nano-zinc oxide can be harmful to coral reefs.

More about harmful reef ingredients here.

Zinc Oxide also has antibacterial and calming properties. It is not water soluble.

Zinc has been used throughout history as an ingredient in paint and medicine. An Indian text from 500BC is believed to list zinc oxide as a salve for open wound. The Ancient Greek physician Dioscorides has also mentioned the use of zinc as an ointment in 1AD.

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.

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.

Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UVA absorber. It is formulated for high UVA protection (320-400 nm) and photostability.

DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%.

UV absorbers are an agent that absorbs UV rays. They protect your skin by using chemical reactions to convert UV rays into heat and energy.

UV rays are a form of electromagnetic radiation from the sun. Other sources include tanning beds and welding torches. Radiation is the emission of energy. UV Rays are divided into 3 groups. UVA (320-400 nm) contains the least amount of energy. They are linked to long term skin damage such as wrinkles and hyperpigmentation. UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA in skin cells. UVB causes sunburns and are thought to be linked to skin cancer. UVC (200-280 nm) contains the highest amount of energy. Our ozone blocks UVC. UVC can also originate from welding torches, mercury lamps, and sanitizing bulbs.

Glycine Max Seed Extract comes from the Soybean. This bean is native to Asia.

Soybeans are rich in antioxidants. Antioxidants may improve the signs of aging.

Studies show soy may help fade hyperpigmentation from UVB. It does so by disrupting the melanin process caused by UVB induced skin inflammation.

Two powerful components found in the wild soybean include genistein and diadzein. These two isoflavones are potent antioxidants with anti-inflammatory properties. Genistein in particular has been found to prevent redness caused by UV exposure.

Soybeans are rich in proteins and are part of the legume family. Foods made with soybeans include tofu, soymilk, edamame, miso, and soy sauce.

Squalane is an emollient that helps the skin hold onto moisture. It's an oily liquid that occurs naturally in certain types of fish and plant oils.

Because squalane boosts hydration in the skin, it also comes with plenty of benefits: it is an antioxidant and can help fight free radicals and skin damage. Squalane is also found to have a detoxifying effect when applied.

Squalane comes from squalene, which occurs naturally within the sebum of our skin. It is one of the oils our skin produces to keep itself hydrated. Squalane is the hydrogenated version of squalene and has a longer shelf life.

Research shows that squalane is non-irritating (even at 100% concentration).

In general, it's a fantastic ingredient. It does a great job at hydrating the skin, and it's suitable for those with sensitive skin.

The source of squalane may impact malassezia / fungal acne. This is because olive oil derived squalane can contain impurities such as fatty acids and plant waxes. Sugarcane derived squalane is recommended for anyone with malassezia concerns.

Is squalane vegan? This depends on the source. Squalane can be derived from both plants and animals. Most squalane used in skincare comes from plants.

Please note: the source of squalane is only known if disclosed by the brand. We recommend reaching out to the brand if you have any questions about their squalane.

Parfum is a catch-all term for an ingredient or more that is used to give aroma to products. Parfum, or fragrance, 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.

In the US, the alternative name for parfum is 'fragrance'. The term '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. One example is Calendula flower extract. Essential oil ingredients still impart a scent or 'fragrance'.

Depending on the blend, it can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Products use parfum often to give products a scent or cover up smells of different ingredients.

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.
