Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Benzyl Alcohol is most commonly used as a preservative. It also has a subtle, sweet smell. Small amounts of Benzyl Alcohol is not irritating and safe to use in skincare products. Most Benzyl Alcohol is derived from fruits such as apricots.
Benzyl Alcohol has both antibacterial and antioxidant properties. These properties help lengthen the shelf life of products. Benzyl Alcohol is a solvent and helps dissolve other ingredients. It can also improve the texture and spreadability.
Alcohol comes in many different forms. Different types of alcohol will have different effects on skin. This ingredient is an astringent alcohol.
Using high concentrations of these alcohols are drying on the skin. They may strip away your skin's natural oils and even damage your skin barrier. Astringent alcohols may also irritate skin.
Other types of astringent alcohols include:
According to the National Rosacea Society based in the US, you should be mindful of products with these alcohols in the top half of ingredients.
Any type of sanitizing product will have high amounts of alcohol to help kill bacteria and viruses.
Learn more about Benzyl AlcoholButyrospermum Parkii Butter is a plant lipid from the fruit of the Shea Tree. It is an effective skin hydrator and emollient.
Emollients help soothe and soften your skin. It does this by creating a protective film on your skin. This barrier helps trap moisture and keeps your skin hydrated. Emollients may be effective at treating dry or itchy skin.
Shea butter is rich in antioxidants. Antioxidants help fight free-radicals, or molecules that may harm the body. It is also full of fatty acids including stearic acid and linoleic acid. These acids help replenish the skin and keep skin moisturized.
While Shea Butter has an SPF rating of about 3-4, it is not a sunscreen replacement.
Shea butter may not be fungal acne safe. We recommend speaking with a professional if you have any concerns.
Learn more about Butyrospermum Parkii ButterThis ingredient is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.
It helps thicken a product's formula and makes it easier to spread by dissolving clumping compounds.
Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid.
While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this.
Learn more about Caprylic/Capric TriglycerideCarbomer is a polymer of acrylic acid. Its main role is to create a gel consistency.
A high amount of carbomer can cause pilling or balling up of products. Don't worry, most products contain 1% or less of carbomer.
Dehydroacetic Acid is fungicide and bactericide. It is used as a preservative in cosmetics. Preservatives help elongate the shelf life of a product.
Dehydroacetic Acid is not soluble in water.
Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Learn more about GlycerinGlyceryl Stearate Se is a self-emulsifying (SE) form of glyceryl stearate. Self-emusifying means this ingredient automatically blends with water. It is an emulsifier, emollient, and cleansing agent.
As an emulsifier, Glyceryl Stearate Se prevents ingredients such as oil and water from separating. It is also a surfactant, meaning it helps cleanse the skin. Surfactants help gather oil, dirt, and other pollutants so they may be rinsed away easily.
Emollients help your skin stay smooth and soft. It does so by creating a film on top of the skin that helps trap moisture in.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.
Learn more about Sodium HydroxideTocopheryl 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.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
