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!
Learn more about WaterPentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can also help thicken or stabilize a product.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

You may know Aloe to be a good sunburn reliever and inflammation reducer. This is because it contains many components that are known to help reduce irritation and itchiness.
Aloe leaves are also great moisturizers. They are naturally rich in polysaccharides, a carbohydrate made of sugars. Polysaccharides are able to mimic the carbs found in the top layer of your skin. This can help keep your skin hydrated.
Aloe contains the antioxidants Vitamins A, C, and E. These vitamins neutralize free radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
Aloe does not protect against UV rays, despite it soothing sunburns.

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 GlycerinSodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:
Learn more about Sodium HyaluronateSodium Ascorbyl Phosphate is a form of Vitamin C. It is the salt of ascorbic acid.
This ingredient is more gentle than ascorbic acid. It is also more stable when exposed to light and oxygen.
Vitamin C helps reduce redness, improve skin texture, reduce the effects of aging, reduce the visibility of dark spots, and brighten skin.
Your skin uses Vitamin C to produce collagen and collagen production plays a role in having a strong skin barrier and plump skin. As an antioxidant, this ingredient also helps reduce the signs of aging such as fine-lines and wrinkles.
VItamin C helps brighten skin by blocking the process of skin darkening.
In a 2011 study, Sodium Ascorbyl Phosphate was found to have antibacterial properties. This may help treat acne.

Learn more about Sodium Ascorbyl PhosphateCitric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.
