Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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!

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 GlycolGlycerin 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.

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.

Its main role is to remove the top layer of dead skin cells, allowing newer skin cells to emerge.
Specifically, AHAs work by breaking down the structural "glue" holding the old skin cells in place. Getting rid of the old skin cells allows skin to regenerate newer skin cells in its place. A build up of dead skin cells can lead to tired and dull looking skin.
Due to this, glycolic acid helps with:
Fun fact: Glycolic acid increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.
When starting glycolic Acid, it is normal to feel slight stinging.
The pH value and concentration of glycolic acid play a role in the effectiveness of the product. Concentrations between 5-20% glycolic acid have been shown to be effective in clinical studies.
Recent studies have shown Glycolic Acid may protect the skin against UV damage. However, you should always wear SPF, especially when using exfoliants.

This ingredient also interferes with the process of hyperpigmentation. This can help with reducing dark spots and uneven tone.
Bisabolol is an antioxidant. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells. By fighting these free-radicals, Bisabolol may slow down signs of aging.
Studies have shown Bisabolol to have antimicrobial properties and may be a fungicide. These properties help preserve a product's shelf life.
All these properties makes bisabolol a great skin barrier helper ingredient.
Bisabolol also helps the absorption of other ingredients.
Note: Synthetic Bisabolol has been shown to be less effective.

This ingredient has many skin benefits:
This ingredient contains polyphenols, a strong antioxidant. Antioxidants help fight off molecules that damage skin cells.
On top of that, the antioxidants in green tea neutralize free-radicals from the sun. This gives the skin some extra UV protection, but should not replace sunscreen.
Many components of tea have anti-inflammatory properties.
Polyphenols and L-theanine help soothe the skin and reduce irritation. The caffeine in Camellia Sinensis Leaf Extract helps calm inflamed blood vessels.
Other compounds found in tea include: Vitamin Bs, linoleic acid, magnesium, calcium, iron, and zinc.
Research has shown both drinking Camellia Sinensis Leaf Tea and applying it to the skin can help boost skin elasticity and hydration. Studies also show using tea extract may reduce sebum, or oil, production.
