Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Behentrimonium Methosulfate is an ammonium salt. It is mainly used to prevent static in haircare products as a surfactant.
Surfactants have differing ends: one side is hydrophilic while the other end is hydrophobic.
Surfactants also help your cleansers remove pollutants more easily from the skin.
Learn more about Behentrimonium MethosulfateButyrospermum 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.

Emulsifiers help prevent the separation of oils and products. Due to its composition, it can also be used to thicken a product or help create foam.
Cetearyl alcohol is an emollient. Emollients help soothe and hydrate the skin by trapping moisture.
Studies show Cetearyl alcohol is non-toxic and non-irritating. The FDA allows products labeled "alcohol-free" to have fatty alcohols.
This ingredient is usually derived from plant oils such as palm, vegetable, or coconut oils. There is debate on whether this ingredient will cause acne.
Due to the fatty acid base, this ingredient may not be Malassezia folliculitis safe.
Learn more about Cetearyl AlcoholThis ingredient is a preservative, antimicrobial, and emulsifier. It is often used in cosmetics for its ability to cleanse, condition, and reduce static.
Cetrimonium chloride is a quaternary ammonium salt, meaning it has a water-soluble structure.
Olea Europaea Fruit Oil is the fixed oil obtained from the ripe fruit of the Olive. In other words - olive oil.
The primary contents of olive oil are glycerides of the fatty acids linoleic, oleic and palmitic.
Olive oil also contains antioxidants such as Vitamin E. Antioxidants may help reduce signs of aging by fighting unstable free-radical molecules. It also contains Vitamins A (retinol), D, and K.
The squalene in olive oil makes it a great emollient. Emollients help soothe and soften your skin by trapping moisture in. This makes olive oil a great skin moisturizer.
Studies show olive oil to have antibacterial and antifungal properties in low concentrations. Another study found olive oil irritated sensitive oily skin. We always recommend speaking with a professional about using this ingredient in your routine.
Due to the fatty acid content, this ingredient may not be fungal-acne safe.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
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.
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.

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!
