Ingredients explained

Water
Est. %80
Function
Origin
The most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Glycerin
Est. %6
Function
Origin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Sodium Hyaluronate
Est. %2
Function
Origin

A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.

Propanediol
Est. %1.9
Function
Origin
An excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Polysorbate 20
Est. %1.8
Function
Origin
A viscous, amber-colored liquid that functions as a solubilizer to disperse small amounts of oil into a large water phase. Polysorbate 20 is frequently used to solubilize fragrance oils into water-based emulsions.
PEG-40 Hydrogenated Castor Oil
Est. %1.5
Function
Origin
A castor oil-derived ingredient often used to incorporate small amounts of oil (such as a fragrance) into a water-based product. PEG-4 HCO is a gold-standard solubilizer and can be used in low amounts due to its ability to solubilize things so well.
