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 GlycolThis 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 TriglycerideCetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.
Its main roles are:
Though it has "alcohol" in the name, it is not related to denatured alcohol or ethyl alcohol.
The FDA allows products labeled "alcohol-free" to have fatty alcohols.
Learn more about Cetyl AlcoholDisodium EDTA plays a role in making products more stable by aiding other preservatives.
It is a chelating agent, meaning it neutralizes metal ions that may be found in a product.
Disodium EDTA is a salt of edetic acid and is found to be safe in cosmetic ingredients.
Learn more about Disodium EDTAGlycerin 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 GlycerinAnother popular name for this ingredient is Synovea HR. This ingredient is a skin lightener and antioxidant.
Like other skin lighteners, it blocks the process of skin darkening. Specifically, this ingredient blocks tyrosinase, the enzyme responsible for darkening skin when exposed to UV.
Hexylresorcinol works well with other ingredients. Studies show this ingredient boosts the effect of niacinamide, various forms of vitamin C, and retinoids.
Many consider this to be a safer alternative to hydroquinone. In fact, this ingredient produces the same results as hydroquinone in lower amounts.
Fun fact: This ingredient can also be found food and medicine for treating skin infections.
Gentle reminder from SkinSort: all skin tones are beautiful!

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Retinyl Propionate is a retinoid. Retinoids are the gold-standard class of anti-aging ingredients.
Most retinoids have to be converted to become effective. For some, this conversion line is long and possible ineffective. The end goal? Retinoid acid, AKA tretinoin.
Retinyl Propionate is an ester of retinol, like Retinyl Palmitate. Though the conversion line is longer for this ingredient - the results seem promising.
A study from 2021 found Retinyl Propionate to be just as effective as retinol . FYI - Retinol is one of the most well-studied OTC ingredients.
Other studies show promising results as well:
Reducing sun damage helps with: reducing the appearance of wrinkles, evening out skin tone, increasing skin plumpness, and decreasing dullness.
Using retinol or any retinoids will increase sun-sensitivity in the first few months. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.

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!
