Hesperidin Methyl Chalcone (HMC) is a modified form of hesperidin, a citrus flavonoid. It has antioxidant properties.

In preclinical research, HMC has been studied for its ability to reduce oxidative stress and inflammation related to UVB exposure. Outside of cosmetics, HMC has been looked at for its effects on capillary leakage and swelling. This is why you'll often see this ingredient in eye creams.

Magnesium Aluminum Silicate is a type of silica. It comes from naturally occuring minerals such as silicate ores and clay.

Magnesium aluminum silicate is used for enhancing texture and as an absorbent. Due to its large molecular size, it is unable to be absorbed into the skin.

Palmitoyl Tetrapeptide-7 (formerly Palmitoyl Tetrapeptide-3) is a synthetic peptide. Its main job is to fight what researchers call "inflammaging".

Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.

Steareth-20 is an emulsifier and solubilizer. It is created from stearyl alcohol with ~20 units of ethylene oxide to give it a strong preference for water.

As an emulsifier, it helps oil-in-water emulsions like lotions, creams, and cleansers stay stable. It also solubilizes small amounts of oil-loving ingredients (like fragrance) into water-based formulas.

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 helps dissolve other ingredients into the formulation.
