Marc Jacobs Beauty Accomplice Concealer & Touch-Up Stick Versus Shiseido Synchro Skin Correcting Gelstick Concealer

CI 77492 is also hydrated iron III oxide. It's sole purpose is to give a yellow hue to products.

Iron III oxides are classified as inorganic chemicals for coloring.

Ci 77499 is also hydrated iron III oxide. It is created from mixing red and black iron oxides. This helps give shades of darkness to a product.

Iron III oxides are classified as inorganic chemicals for coloring.

Ci 77891 is a white pigment from Titanium dioxide. It is naturally found in minerals such as rutile and ilmenite.

It's main function is to add a white color to cosmetics. It can also be mixed with other colors to create different shades.

Cyclopentasiloxane, or D5, is a silicone used to improve texture of products and trap moisture.

D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.

Diphenylsiloxy Phenyl Trimethicone is a silicone. It has a high refractive index and adds shine to formulations.

According to the safety review by the Cosmetic Ingredient Review (CIR) Expert Panel, it is safe for use in cosmetics under the current practices and concentrations.

Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.

Topically, glycerin does several things at once:

Hydrogenated Polydecene is a synthetic emollient. It forms a non-occlusive film on the skin's surface to provide a silky feel without being greasy.

In vivo studies in volunteers with atopic and dry skin showed no irritation or intolerance. The volunteers also saw a positive effect in dryness, scaling, and roughness after 28 days of use.

Hydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.

In one study, Hydrogenated Polyisobutene showed better skin hydration levels than Caprylic/Capric Triglyceride. As an emollient, it helps keep your skin soft and hydrated by trapping moisture in.

Mica is a naturally occurring mineral used to add shimmer and color in cosmetics. It can also help improve the texture of a product or give it an opaque, white/silver color.

Serecite is the name for very fine but ragged grains of mica.

Microcrystalline Wax is derived from petroleum through a de-oiling process, then highly refined and purified before use in cosmetics.

In skincare formulations, it is used to improve texture and create a smooth, even consistency. It also helps stabilize products by preventing ingredients from separating.

Paraffin is a solid wax that pulls its weight as an emollient, occlusive, and consistency-booster.

It softens skin and lays down a protective film to slow water loss and gives products a stable body and structure.

Polyethylene is a synthetic ingredient that helps the skin retain moisture. It is a polymer.

It is also typically used within product formulations to help bind solid ingredients together and thicken oil-based ingredients. When added to balms and emulsions, it helps increase the melting point temperature.

This ingredient is a solvent. It helps dissolve active ingredients and alter the texture of products.

Propylene Carbonate is commonly used in makeup and with clay, such as montmorillonite or bentonite.

Tocopherol is a fat-soluble antioxidant known as Vitamin E.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.

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.
