Beeswax is natural wax produced by honey bees and can be synthetically created. It consists mainly of fatty acid esters and long-chain alcohols.

In cosmetics, beeswax is a emollient. Due to its waxy structure, it creates a protective barrier. This barrier prevents water from evaporating off the skin.

It is used to stabilize the mixing of water and oil ingredients. By preventing these ingredients from separating, it can help elongate shelf life. It can also help thicken the product's texture.

Silica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.

Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.

This ingredient is a semi-synthetic polymer created from cellulose. In case you need a refresher, cellulose is the main component of plant cell walls.

Hydroxypropyl Methylcellulose has many uses:

Inositol is a sugar alcohol naturally found in the human body. Our bodies use this ingredient in the process of growing new cells.

Studies show inositol to be a key component for keratinocyte growth.

3-Laurylglyceryl Ascorbate is an antioxidant.

Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.

One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.

Sodium 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.

Pullulan is a low viscosity polysaccharide (a long chain carbohydrate) with binding and film forming properties when dissolved in water. It is used to create a "silicone-like" or silky feel in cosmetics without adding viscosity.

According to a manufacturer, this ingredient's ability to easily dissolves makes it a great carrier for active ingredients.

Isostearic acid is a saturated fatty acid. Its structure makes it a great surfactant.

Surfactants help decrease the surface tension between two liquids. This property also makes it an effective emulsifier. Emulsifiers help prevent waters and oils from separating in a product.
