Learn more about WaterPalmitoyl Tetrapeptide-7 is a peptide. Peptides are building blocks for protein.
This ingredient consists of four amino acids and palmitic acid. These amino acids are arginine, proline, glutamine, and glycine.
This ingredient has many benefits. These benefits include boosting collagen production, fighting inflammation, and reversing UV damage.
By preventing our bodies from producing interleukins, Palmitoyl Tetrapeptide-7 helps fight inflammation. An interleukin is a chemical that signals to the body to produce an inflammatory response. Interleukin production is accelerated by UV radiation.
Palmitoyl Tetrapeptide-7 tells our body to create more collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
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 GlycerinButylene 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.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.
Carbomer is a polymer of acrylic acid. Its main role is to create gel consistency within products.
Carbomer is commonly found in many types of cosmetics products. It is found to be safe in concentrations up to 15%. However, a high amount of carbomer can cause pilling or balling up of products. Most products contain 1% of less of carbomer.
