Ingredients Explained
Ascorbyl Tetraisopalmitate is a version of ascorbic acid, or Vitamin C.
This ingredient has many benefits including reducing wrinkles, skin soothing, dark spot fading, and fighting against free radicals.
It helps with dark spot fading by interfering with the process of skin darkening, helping to reduce hyperpigmentation. Like other forms of vitamin C, this ingredient encourages the skin to create 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 combined with acetyl zingerone.

According to a manufacturer, it evaporates fast on skin and leaves behind a non-greasy and velvety finish. This also helps other ingredients like UV filters and pigments distribute evenly.
In 2020, the Research Institute for Fragrance Materials (RIFM) reviewed dodecane and found it to clear all tests. The amount typically used in cosmetics is also well below the threshold where skin allergies would be a concern.
This ingredient can be sourced from either petroleum fractionation or plant-based feedstocks.

Hemp oil is an emollient and nourishes the skin. It contains many fatty acids such as linoleic acid, amino acids, phospholipids, and vitamin E.
The difference between hemp and cannabis is their psychoactive component. Hemp has low amounts of THC.

The inner leaf gel it comes from is mostly water (~99-99.5%) and the remaining fraction is made up of pretty good stuff: polysaccharides, vitamins, phenolics, and enzymes.
Its headline job is hydration.
The star polysaccharide in aloe, acemannan, is a humectant that retains moisture and helps reduce trans-epidermal water loss.
Aloe also has real soothing credentials; it contains anti-inflammatory compounds like bradykinase and C-glucosyl chromone that help calm irritation and redness.
On the repair side, lab work shows that acemannan wakes up your skin's repair cells (fibroblasts), prompting them to multiply and speed up healing.
There's some human data for cosmetic benefit too: a cream containing 10% Aloe Barbadensis leaf extract improved skin hydration and elasticity in a real-use study.
Safety-wise, this ingredient is well-regarded with just one rare downside; there have been some case reports of acute eczema, contact urticaria, and dermatitis in people who applied aloe-derived ingredients topically. Those with a known aloe or Liliaceae sensitivity should patch test.
Typical use levels range widely, from under 1% up to 90%+ depending on the format and the effect you are after.

It is an emollient and skin conditioning agent that is able to integrate seamlessly into the skin's lipid barrier without clogging pores.
This is due to how structurally similar it is to what your skin already produces.
Though it is mostly an emollient that helps soften and hydrate skin, it also has some humectant and occlusive action. Humectants help the skin retain moisture while occlusives seal it in, making squalane a triple-threat moisturizer.
Research shows it has antioxidant capabilities that help protect against stressors like UV exposure, specifically UVA induced oxidative stress. This study also found that it supports collagen biosynthesis in human dermal fibroblasts.
No clinical study has reported significant adverse effects and irritation reactions are very rare from this ingredient (even at 100% concentration).
Overall, it's a fantastic ingredient for hydration and is suitable for all skin types.
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.

Though squalane is often called an oil, it’s technically not one. It is a hydrocarbon, meaning it is only made of carbon and hydrogen. True oils are triglycerides and made of fatty acids and glycerol.
The term “oil-free” isn’t regulated so companies can define it however they want. Some exclude all oils, while others just avoid mineral oil or comedogenic oils.
Squalane has a comedogenic rating of 1 from the original 1972 study that tested raw ingredients under occlusion on rabbit ears. This system is not standardized or peer-reviewed, and using the raw ingredients is very different from how diluted cosmetic formulations are used on human skin.
A comedogenic rating of 1 means it is "unlikely to clog pores" according to the original rating system.
The overall formula of a product matters more than the individual ingredients on whether or not it will cause clogged pores.

Camellia Sinensis Seed Oil is rich in oleic acid. This makes it an effective moisturizer. By drawing moisture to the skin, Camellia Oleifera Seed Oil helps keep your skin hydrated.
Other components of Camellia Sinensis Seed Oil includes Vitamin E and polyphenols. These are antioxidants that may help slow down the signs of aging. Antioxidants help fight free-radicals, or unstable molecules that can damage our skin cells.
Camellia Sinensis Seed Oil also has anti-inflammatory properties.
The seed oil comes from the dried kernels of the plant.

This ingredient is also known as oat kernel oil. It's an emollient and skin conditioning agent that is great for barrier support, hydrating skin, and calming irritation.
The fatty acid profile is dominated by linoleic acid (~22.8-43.1%), oleic acid (~31.4-51.3%), and palmitic acid (~13.9-18.8%).
Plus, it contains ceramides, phytosterols, phospholipids, vitamin E, and avenanthramides (oat's signature anti-inflammatory polyphenols).
One study found an oat lipid extract applied to human skin cells switched on receptors that tell skin cells to mature properly and make more barrier lipids (including a 70% boost in ceramides).
Basically, oat kernel oil doesn't just sit on top of skin, it nudges your skin to build more its of its own barrier.
Typical usage levels range from 1-10%.
Note: This ingredient may not be fungal acne safe due to the fatty acids present.

Aging and environmental exposure diminishes our skin's natural ubiquinone levels. This is much like our natural collagen and elastin.
The good news is: studies show applying this ingredient topically replenishes ubiquinone levels in our skin. This also comes with a ton of skin benefits. These benefits include:
Ubiquinone is considered a large molecule and cannot be absorbed into the lower layers of skin. This is why it is believed to be such an effective antioxidant: it protects our skin in the upper layers and prevents damage in the deeper layers.
When used in sunscreen, ubiquinone is shown to increase ingredient stability, increase SPF factor, and add to infrared protection.
Fun fact: ubiquinone is fat-soluble.
