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.

This ingredient is the fixed oil extracted from seeds of the desert shrub Jojoba. It is more commonly known as jojoba oil. The seed oil is liquid wax ester from the plant. It is non-comedogenic.
Jojoba oil does not contain fragrance and has many fatty-acids, making it a great soothing ingredient. Jojoba contains Vitamin E, a great moisturizing ingredient. Vitamin E is also an antioxidant. Antioxidants help protect your skin against free-radical damage. This may help in anti-aging.
Jojoba seed oil is a humectant, meaning it helps draw moisture from the air. This helps keep your skin hydrated.
While jojoba has antibacterial properties, it is only able to kill some bacteria. It has also been shown to help in wound healing. Indigenous cultures have used jojoba as a moisturizer and to help treat burns.
It is found to be similar to natural human skin sebum, so it has a great effect on dry skin. Jojoba oil may even help with regulating sebum production.
Although jojoba oil is non-comedogenic, we recommend speaking with a professional about using this ingredient if you have any concerns.
Jojoba oil may not be fungal acne safe. We recommend speaking with a professional if you have any concerns.
Jojoba is native to the southwestern US.

Ascorbyl Tetraisopalmitate is a version of ascorbic acid, or pure Vitamin C.
Ascorbyl Tetraisopalmitate has many benefits including reducing wrinkles, skin soothing, dark spot fading, and fighting against free radicals.
Ascorbyl Tetraisopalmitate interferes with the process of skin darkening, helping to reduce hyperpigmentation. It also encourages the skin to produce more collagen.
As an antioxidant, it helps fight free-radicals. Free-radicals are molecules that may damage your skin cells.
One study found Ascorbyl Tetraisopalmitate to degrade in sunlight, but is stabilized when conbined with acetyl zingerone.

Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.
One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.
Tocopheryl Acetate is commonly found in both skincare and dietary supplements.

Prunus Amygdalus Dulcis Oil comes from the sweet almond, a tree native to Iran. This oil has no fragrance and is non-volatile.
Almonds contain healthy fats, vitamins, and minerals. It is a rich source of Vitamin E, a great antioxidant and skin conditioning ingredient. Sweet almond oil contains fatty acids such as linolenic acid and triglycerides.
The content of sweet almond oil makes it a great emollient; it can help soften and hydrate your skin. Emollients create a barrier over your skin to trap moisture in. Sweet almond oil has antioxidant properties. This may help with anti-aging, as antioxidants help fight free-radicals. Free-radicals are unstable molecules that may damage your skin's cells.
Those with an almond allergy should be careful of this ingredient and speak with a professional about using it in your skincare.
This ingredient may not be fungal-acne safe.

Limonene is a fragrance that adds scent and taste to a formulation.
It's found in the peel oil of citrus fruits and other plants such as lavender and eucalyptus. The scent of limonene is generally described as "sweet citrus".
Limonene acts as an antioxidant, meaning it helps neutralize free radicals.
When exposed to air, oxidized limonene may sensitize the skin. Because of this, limonene is often avoided by people with sensitive skin.
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.

As Vit C is water soluble, it breaks down when exposed to O2, due to this most Vit C products are constantly losing their potency with every use....
