Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Aloe Barbadensis Leaf Juice comes from leaves of the aloe plant. Aloe Barbadensis Leaf Juice is best known for helping to soothe sunburns. It is also anti-inflammatory, moisturizing, antiseptic, and can help heal wounds.
Aloe is packed with good stuff including Vitamins A, C, and E. These vitamins are antioxidants, which help fight free-radicals and the damage they may cause. Free-radicals are molecules that may damage your skin cells, such as pollution.
Aloe Barbadensis Leaf Juice also contains sugars. These sugars come in the form of monosaccharides and polysaccharides, folic acid, and choline. These sugars are able to help bind moisture to skin.
It also contains minerals such as calcium, 12 anthraquinones, fatty acids, amino acids, and Vitamin B12.

As a clay, bentonite is often used to absorb excess oil and provide exfoliation. It has also been shown to have some antibacterial and anti-inflammatory properties. Studies show bentonite was effective at calming dermatitis from poison ivy and in diaper dermatitis of infants. Bentonite has also been shown to act as a barrier against toxic compounds on your skin.
Sunscreens containing bentonite display higher water resistance and stay on the skin for much longer. The sunscreens containing bentonite also show higher potency and UV light absorbtion.
Bentonite is naturally created from volcanic ash and several natural weathering/hydrothermal processes.
A common usage of bentonite is removing excess protein from white wines. Bentonite contains a property of being able to absorb large amounts of protein from aqueous solutions.
Phyllosilicate clay has a structure formed by sheets.

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 GlycerinKaolin is a clay. It is used for oil control and to help minimize pores. Like other clays, kaolin has the ability to absorb excess sebum or oil. This can help clean out pores and mattify the skin.
Some types of kaolin may have exfoliating properties. When water is added to kaolin, it becomes a paste with small abrasive particles.
Most kaolin is a white color, but may be pink/orange/red depending on where it comes from.
The name 'kaolin' comes from a Chinese village named 'Gaoling'. Kaolin clay comes from rocks rich in kaolinite. Kaolinite, the mineral, has a silicate layered structure. Kaolinite is formed from chemical weathering of aluminum siilicate minerals.
Besides skincare, kaolin is commonly used to make glossy paper, in ceramics, toothpaste, and as medicine to soothe stomach issues.

As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.
Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.
The lauric acid used to create Polysorbate 20 is often derived from coconuts.
Polysorbate 20 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!
Learn more about WaterZinc Oxide is a mineral broad-spectrum UV filter; it is the broadest UVA and UVB reflector approved by the FDA. While it is most commonly man-made for cosmetics, it can naturally occur in zincite, a rare mineral.
Today, traditional and nano-sized zinc oxide can be found in beauty products. Nano-sized zinc oxide can enhance a product's UV protection. While it is not believed to have a negative effect on skin, nano-zinc oxide may be harmful to coral reefs - though the verdict is not entirely out on this one.
Zinc Oxide also has antibacterial and calming properties. It is not water soluble.
Zinc has been used throughout history as an ingredient in paint and medicine. An Indian text from 500BC is believed to list zinc oxide as a salve for open wound. The Ancient Greek physician Dioscorides has also mentioned the use of zinc as an ointment in 1AD.
