Ingredients Explained
Magnesium Sulfate is a salt. More specifically, it is an epsom salt, or the bath salt used to help relieve muscle aches.
Despite having ‘sulfate’ in the name, it isn’t a surfactant or cleansing agent like sodium lauryl sulfate. Unlike those sulfates, magnesium sulfate doesn’t have the same cleansing or foaming properties (it's simply a type of salt).
In cosmetics, Magnesium Sulfate is used to thicken a product or help dilute other solids. It is a non-reactive and non-irritating ingredient.
One study shows magnesium deficiency may lead to inflammation of the skin. Applying magnesium topically may help reduce inflammation.
You can find this ingredient in sea water or mineral deposits.
Learn more about Magnesium SulfatePhenol is an antimicrobial preservative used to extend a product's shelf life by inhibiting the growth of bacteria and mold. It's most commonly found in lip care, cleansers, and treatments at concentrations of 1–2%, and can also function as a denaturant, deodorant, or fragrance ingredient.
Unlike most cosmetic preservatives, phenol can damage skin at the concentrations typically used in products. Research has identified roughly 1.5% as the threshold at which phenol begins to cause skin damage - sitting within the range it's normally formulated at.
It works by denaturing proteins, which is what gives it both its antimicrobial activity and its potential to cause chemical burns, redness, peeling, or stinging. Phenol also has a mild local anesthetic effect, so irritation may not be felt right away even when damage is occurring. The lips and other thin-skinned areas are especially susceptible.
The use of phenol in cosmetics is prohibited in the European Union and Canada. In the United States, it remains permitted primarily in OTC drug products such as oral analgesics and medicated lip balms.

Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
