Dimethicone is the most popular silicone. It makes the skin softer and forms a film adding smooth and silky feeling. This film not only improves how the skin feels but also works as a protective barrier. It also improves the visual appearance of your skin by filling small wrinkles. That's why some people think dimethicone removes wrinkles. Actually, it does not. It's just a visual effect.
One of the most important characteristics of this component is that it helps to spread other ingredients evenly on the surface to provide good coverage. It's very important because you want all your skin cells to receive an equal proportion of the components.
Dimethicone is considered as safe, but remember that it is rather difficult to wash off! This may lead to clogged pores and acne if you use it too often and don't wash off quite well.

Water
Roles: Solvent
Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.
Alcohol Denatured is a great bacteria killer. Manufacturers often put it inside products to increase their shelf life.

Zinc Oxide
Roles: Bulking, Colorant
UV Protection
Antiseptic
Comedogenic rating [ 1 ]
Good for oily skin
Zinc Oxide is a great physical sunscreen, meaning it deflects the UV rays. It’s the only natural mineral sun protector recommended by the FDA for babies. It’s good for sensitive skin because it’s less irritating than chemical sunscreens.
It has very nice spectrum protection. It helps to protect from UVA I, UVA II, and UVB and nowadays it’s the broadest range of sunscreen used in cosmetics. In other words, it’s brilliant in its league.
The negative side is that it can feel heavy on the skin. It can leave a slight whitish tint on the surface of the skin and some people may not like this. Keep in mind that it’s relatively easy to wash off, so it’s better to use water-resistant sunscreens if you are swimming.
5
Isododecane
Roles: Emollient, Fragrance, Solvent
Softening
Isododecane is an emollient and a good base for colorants. Very often used in powders and shades because it spreads on the skin nicely. It also helps to soften the skin and helps to lower water loss making all the moisturizing components work better.
Octocrylene is an organic chemical sunscreen. It protects against UVA and UVB rays that can damage your skin or even lead to melanoma. It also stabilizes other sunscreen ingredients in a formulation and increases the water resistance of a product. It is approved by the FDA in concentrations of up to 10%. It’s not a very effective component on its own, that’s why manufacturers combine it with other chemical sunscreens.
Glycerin is one of the most outstanding and helpful skincare components. It's used in many skincare products because it works and provides notable results. It's one of the best moisturizers. Molecules of Glycerin can absorb water and deliver it into deep layers of the skin making it hydrated.

Titanium Dioxide
Roles: Colorant
UV Protection
Titanium Dioxide is a very effective sunscreen. It belongs to physical sunscreens, meaning it reflects the UV rays like a mirror. The component is a mineral with white color. That’s why it’s also used in different powders as a pigment or brightener.
The component can be both safe and unsafe. It’s reported to be possibly carcinogenic to humans when inhaled. That’s why we don’t recommend using products where TiO2 is used in the form of powder and can be inhaled.
Sometimes it can be a nanoparticle. We recommend avoiding this form because it’s not researched well enough. A safer option is to use a non-nano form.
Silica is used for improving texture of the product. It helps the product to spread out evenly. Very often it’s used in different exfoliants as an abrasive. It's safe and non-toxic.
Stearic Acid doesn’t belong to aggressive acids. It’s a fatty acid that can be found in Shea Butter, Cocoa Butter, and many natural butters and oils. The component is mostly used for formulation purposes. It makes the product spread and feel better. It’s one of the most important fatty acids in our skin cells.

Trisodium EDTA
Roles: Chelating

Fragrance
Roles: Deodorant, Fragrance, Masking
Fragrances
Fragrance is a mix of chemical ingredients (usually 20-30 chemicals but up to 200 sometimes) that help the product to smell better. It can hide many bad things. Synthetic fragrances may contain many different chemicals, but manufacturers don’t want to reveal each of them for some reason and hide them behind the word "Fragrance".
Butylene Glycol is a very popular synthetic alcohol. It helps the product to absorb deeper and faster. It is also a solvent for other ingredients. As for the skin benefits, it helps to attract water and helps to make the skin softer.
BHT is a stabilizer and antioxidant. It helps to keep the product fresh for a long time, preventing the oxidization of components. It is stable even in high temperatures, that’s why it’s an essential component in some products. It also protects the skin from free radicals. As for safety, the component isn't researched very well. It’s considered to be safe in low concentrations. But there is still not enough scientific data collected.

Iron Oxides
Roles: Colorant
Moisturizing
Iron Oxides are colorants. They give different colors to the product: yellow, red, or black. Different scientific researches show that they are much safer than other organic colorants. That's because they are much more stable and they don’t provoke allergic reactions. Though they can be received from minerals organically, manufacturers don’t use natural Iron Oxides. They chemically synthesize them in a laboratory to get a pure component without extra chemicals.
Green Tea Leaf Extract is a great antioxidant often used in Korean skincare products. It contains EGCG - the most effective flavonoid. It makes the skin look fresh, fills it with vitamines, and helps to prevent aging. It also helps to lower inflammation.

Phenoxyethanol
Roles: Fragrance, Preservative
Antiseptic
Phenoxyethanol is one of the most popular preservatives. It kills bacteria and makes the product live longer. Manufacturers like this ingredient because it can dissolve in any liquid, even in oils.
Another purpose of this component is the fixation of aromas in perfumery. Phenoxyethanol is also used as a strong antiseptic and a good antibacterial agent. It is widely used in dermatological cosmetics alongside natural antiseptics such as chamomile, sage, and calendula.
