Dimethicone
Roles: Skin conditioning, Antifoaming, Emollient
Silicones
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.
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.
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.
Cyclopentasiloxane is a fluid silicone. It’s non-greasy and doesn’t have any scent or color. It evaporates pretty fast which makes this ingredient essential when it comes to making products that have to dry quickly. It also gives a nice silky feeling when you apply the product to the skin and hair. It leaves a thin film that protects the skin after evaporation.
Cyclopentasiloxane is chemically neutral, meaning it doesn’t react with other components.
Betaine is used a lot in “organic” skincare products. It is a good moisturizer that not only hydrates the skin but also strengthens the cell membrane. This helps to lower the water loss over time. It also softens the skin and reduces irritation and redness. It’s often used at a 3-5% concentration depending on the product.
Sodium Hyaluronate is an amazing component! It plays very important role in skin hydration process. It helps to maintain water balance and lower water loss. Scientists have found a direct dependence between the level of Sodium Hyaluronate in cells and skin aging. That's why this component is so much important. It must be in your routine if you want to have a healthy and fresh looking skin.
Some people think that Sodium Hyaluronate and Hyaluronic acid are different names of the same component, but it is not entirely correct. Hyaluronic acid is a different chemical but with similar effects. Actually, Sodium Hyaluronate is used in cosmetics much more often because it’s more stable and has much better resistance to oxidation.
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.
Tocopheryl Acetate is a form of Vitamine E. It’s used as an alternative to Tocopherol because it is more stable in the formulation. It has all the positive effects of Tocopherol plus better stability. It’s a brilliant component. It conditions and nourishes the skin helping it to resist aging. It also helps to protect the skin from the sun. High concentrations of Tocopheryl Acetate can lead to irritation and allergic reactions.
Castor Seed Oil is a cosmetic ingredient people know and use from ancient times. It was used in ancient Egypt for eyebrow and hair care. It’s a great moisturizer for people with dry skin. It helps to reduce small wrinkles and recover damaged skin. It fights bacteria and can be used to lower acne inflammation.
Squalane is a more stable equivalent of Squalene. It is a very important component of our skin. It’s a major part of natural sebum that forms a protection barrier on the skin's surface. If the barrier isn’t strong enough, your skin will become more sensitive. Squalanehelps to keep skin hydrated, protects it from the negative impact of the environment, lowers irritation, stimulates regeneration, and removes dryness. It is accepted by our skin very well and will not cause allergic reactions.
Cetearyl Alcohol is used mostly for formulation purposes. It’s a very good emulsifier and emulsion stabilizer. It helps the ingredients mix better and it makes the product spread on your skin evenly. It also makes the product thicker. It doesn’t belong to harmful alcohols and it will not dry your skin.
Polysorbate-60 is an emulsifier, foam stabilizer, and surfactant. It’s considered to be safe but if the product contains PEG ingredients, Polysorbate may produce 1,4-Dioxane which can be harmful to your health.

Carbomer
Roles: Emulsion stabilizer, Gel forming, Viscosity controlling
Moisturizing
Carbomer is used for formulation purposes. It helps to control the viscosity and flow of a product. It’s considered safe but only if it’s well purified. Poorly purified carbomers may contain benzol which may lead to irritation.
Sodium Lactate is very effective for recovering the natural lipid layer of the skin. It’s safe and doesn’t provoke negative reactions. It provides a strong moisturizing effect. It’s a nice soothing ingredient.

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.

Disodium EDTA
Roles: Chelating, Viscosity controlling
Disodium EDTA is an emulsion stabilizer and chelating agent. It deactivates the metal ions preventing them from reacting with other active ingredients. It improves the stability of a cosmetic formula and keeps the product’s consistency, texture, and pH unchanged. It doesn’t have any skincare effects and is used for formulation purposes only.

Potassium Sorbate
Roles: Fragrance, Preservative
Antifungal
Antiseptic
Potassium Sorbate is a preservative that increases the shelf life of the product. It’s a great alternative to parabens. That's why manufacturers like to use this component. It is safe in concentration of up to 10% but it is used in cosmetics in amounts of 1% or even lower.
