Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Acacia Senegal Gum has skin soothing, thickening, and formulation stabilizing properties. It comes from the Acacia tree that is native to sub-Saharan Africa.
Bentonite is an aluminium phyllosilicate clay with great absorbent properties. The name 'bentonite' comes from the area where the largest source is found: Fort Benton, Wyoming.
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.

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 GlycolPhenoxyethanol 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.
Sulfur is a commonly occurring element on Earth (and our universe!). In cosmetics, it helps kill bacteria, reduces sebum, and provides exfoliation. This makes it an effective ingredient to reduce breakouts and fight acne.
As a ketayolytic agent, it breaks down the top layer of skin. This is a form of exfoliation and may help decrease acne and hyperpigmentation.
Studies show sulfur has antibacterial and antifungal properties. Sulfur can be drying if used excessively or at higher concentrations. We recommend speaking with a medical professional if you have any concerns.
Ancient Greece, India, China, and Egypt have used sulfur in both traditional medicines and for household use.

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!

It can help reduce redness, regulate sebum, and promote the general healing process of the skin.
Zinc PCA tends to be especially useful for those with oily, acne-prone skin. It's certainly an ingredient worth trying out!
