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's there to help dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Glycerin is already naturally found in your skin and helps moisturize and protect your skin. A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

Glycerin is a humectant, helping the skin retain moisture by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin. Having moisturized skin helps improve the skin barrier. Your skin barrier protects against skin 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, animal sources include tallow. It is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English while British English uses Glycerol/Glycerine.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

Ammonium Acryloyldimethyltaurate/Vp Copolymer (let's call it AAVC for short) is a synthetically created polymer. It's used as a film-forming agent and used to thicken the consistency of products.

AAVC is able to increase the consistency and viscosity of products due to its large molecule size. It also prevents ingredients from separating.

Leuconostoc/Radish Root Ferment Filtrate is a natural preservative. It comes from fermenting radish roots with a bacteria called leuconostoc. Leuconostoc comes from lactic acid. This bacteria is used to make the traditional Korean side-dish, kimchi. It is also used to make sourdough bread (both incredibly yummy foods).

Leuconostoc/Radish Root Ferment Filtrate has antimicrobial properties and helps prevent the growth of bacteria in a product.

It is believed the preservation property comes from salicylic acid and ammonium salt, neither of which are involved in the fermentation process.

Polysorbate 20 is made by combining ethoxylation of sorbitan, ethylene oxide, and lauric acid. It is a mild cleansing agent, surfactant, and emulsifier.

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 is not fungal acne safe.
