Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
Diglycerin is a humectant. It is derived from glycerin, which is naturally found in your skin.
Propanediol helps absorb ingredients into your skin, boosting their benefits. It can act as an emollient, making your skin softer. Propanediol can help products last longer by boosting the properties of preservatives within the formulation.
Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.

The PCA stands for pyrrolidone carboxylic acid, a natural amino acid derivative.
Sodium PCA is a has conditioning, anti-inflammatory, and humectant properties. Humectants help hydrate your skin by drawing moisture from the air. This helps keep your skin moisturized.
Learn more about Sodium PCASodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
