Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.

Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.

Ethylhexyl Palmitate is created from 2-ethylhexyl alcohol and palmitic acid. It is a fatty acid ester.
The fatty acid content of Ethylhexyl Palmitate makes it an emollient. Emollients help soften and hydrate your skin by trapping moisture within.
Ethylhexyl Palmitate is also used to help improve the texture of cosmetics. It helps other ingredient dissolve in products and help disperse ingredients more evenly. In fact, it is commonly used to evenly mix sunscreen ingredients such as avobenzone and ethylhexyl triazone. It can also help stabilize the fragrances in a product as a fragrance fixative.
Ethylhexyl Palmitate can be used to substitute mineral oil.

This Vitamin C is not for beginners. I got a chemical burn because of this and had to take a break with some actives to restore my skin barrier. Turns out that I still had to dilute it with another cream / moisturizer so that my skin doesn't get irritated. I think there are better Vitamin C products out there. I guess a good point of this Vitamin C is that you don't have to refrigerate it and it doesn't oxidize.
