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.

Glycine Soja Oil comes from the soybean. Glycine Soja is native to eastern Asia.

Soybean oil is an emollient. It is rich in antioxidants and fatty acids including palmitic, stearic, oleic, and linoleic acids.

As an emollient, the fatty acids in soybean oil helps keep your skin soft and hydrated. It does so by creating a film on top that traps moisture in.

Soybean oil is also rich in vitamin E, a potent antioxidant. Vitamin E is also anti-inflammatory and provides a soothing effect.

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

This ingredient may not be malassezia folliculitis, or fungal-acne, safe.

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

Retinol is a form of Vitamin A and proven to help with anti-aging.

It promotes collagen production, increases new cell turnoever, and protects your skin as an antioxidant.

Retinol boosts collagen production and increases cell turnover. This makes retinol effective in removing wrinkles, fading dark spots, and reducing the appearance of pores.

Retinol is less effective when exposed to sun. Be sure to look for appropriate packaging to keep your retinol potent.

Using retinol and retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.

We recommend speaking with a medical professional about using this ingredient during pregnancy.

Retinol may cause irritation in some people, so be sure to patch test. Experts recommend 'ramping up' retinol use: start using this ingredient once a week and work up to using it daily.

Caprylic/Capric Triglyceride is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.

Within a product, Caprylic Triglyceride can thicken the product and make spreadability easier by dissolving clumping compounds. An added benefit of Caprylic Triglyceride is its antioxidant properties.

Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid. Caprylic Triglyceride has not been found to be toxic for human use in concentrations under 50%.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this.

BHT is a synthetic antioxidant. As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.

BHT also helps stabilize products and prevent them from degrading. Many products are sensitive to air and light. BHT prevents them from breaking down when exposed.

Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.

Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.

Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.

You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.

There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

Elaeis Guineensis Oil comes from the African Palm tree. This tree is native to Western and Southwestern Africa.

This oil is rich in antioxidants such as Vitamin E. Antioxidants may help with anti-aging.

The Vitamin E and fatty acid content give palm oil a skin-hydrating property. Emollients help trap moisture in by creating a film on the skin.

Palm oil is created by either squeezing the fruit or crushing the kernel at the center of the fruit. In the 1800s, archaeologists discovered a 6000 year old Egyptian tomb containing palm oil.

Palm oil is controversial due to its social and environmental impacts. Several organizations are working to make palm oil harvest more sustainable, such as the RSPO.

Hydroxymethoxyphenyl Decanone is a synthetically created molecule made to mimic ginger extract.

Ginger has anti-inflammatory properties and helps to soothe skin.

According to one study, it is an HA booster, antioxidant, and anti-irritant.

In this study, this ingredient was able to stimulate higher hyaluronic acid levels of the dermal and epidermal layers on a skin-like model. Hyaluronic Acid is a humectant, which means it helps attract moisture to your skin. Humectants help keep skin hydrated.

As an antioxidant, Hydroxymethoxyphenyl Decanone is able to fight off damage from free-radical molecules.

Broke me out
I have oily and acne prone skin and my face was on the road to recovery. I thought adding a retinol was a good idea and they marketed that this retinol oil is good for any skin type even though it is oily. It broke me out and gave me a scar within a week. It gave me an acne that was deep inside of my skin. I wouldnt recommend it to oily and acne prone skin people.
