Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Learn more about Butylene GlycolCaprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
Learn more about Caprylyl GlycolCarbomer 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.
Dextran is a sugar (polysaccharide) with skin hydrating properties.
Fun fact: Louis Pasteur first discovered this ingredient as a microbial product in wine.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.
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 GlycerinLecithin is a term for a group of substances found in the cell membranes of plants, animals, and humans. They are made up of mixture of phospholipids.
This ingredient has emollient and emulsifying properties.
As an emollient, lecithen helps soften the skin and creates a barrier to keep moisture in.
As an emulsifier, it also helps prevent water and oil ingredients from separating. Lecithin can also help ingredients be better absorbed by the skin.
This is because the phospholipids in lecithin produce liposomes. Liposomes help other ingredients get through the skin barrier.
Depending on the source of this ingredient, lecithin may not be fungal acne safe. This is because some sources of lecithin come from soybean oil, which may feed the malassezia yeast that feeds fungal acne.
We recommend reaching out to the brand you are purchasing from to inquire about the source of their lecithin.
Some other names for this ingredient include soy lecithin and deoiled soy lecithin.
Learn more about LecithinPhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Phospholipids are naturally found in our skin as they are the main component of cell membranes. Phospholipids have humectant, emollient, antioxidant properties.
Phospholipids are complex lipids that contain glycerin, two fatty acids, and a phosphate group. Some foods that contain phospholipids include soybeans and milk. The phospholipids found in soy come from Lecithin. This ingredient can also be synthetically created.
Due to their hygroscopic nature, they act as both humectants and emollients. Humectants draw moisture from the air to your skin, while emollients help trap moisture in.
The phospholipids in our skin can be naturally depleted. Replenishing the phospholipids in our skin can help hydrate your skin.
Studies show phospholipids display antioxidant activity and may help with reducing the signs of aging.
This ingredient is non-occlusive.
Some types of phospholipids:

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
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!
