Myristyl Myristate is an emollient. It makes the product look consistent and feel smooth on the skin. The negative side is that it has a very high comedogenic rating. It may lead to clogged pores if you suffer from acne.

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.

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.

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.

Ceramide NP is one of the most important ceramides found naturally in human skin. It plays a key role in maintaining a strong, healthy moisture barrier — the skin’s protective shield. When this barrier is damaged, skin becomes dry, irritated, and more sensitive. It helps restore that balance.

In skincare formulas, the component works by filling in the microscopic gaps between skin cells, much like mortar between bricks. This strengthens the outer layer of the skin, reduces moisture loss, and enhances overall resilience. Products containing Ceramide NP are especially beneficial for dry, sensitive, or compromised skin, including conditions like irritation from over-exfoliating or cold weather exposure.

Its biggest advantage is biocompatibility: Ceramide NP closely mimics the skin’s own natural ceramides, making it highly effective and well-tolerated. When combined with cholesterol and fatty acids, its performance is even better, helping to rebuild the lipid barrier more efficiently.

Overall, Ceramide NP is a gentle yet powerful ingredient that supports long-term skin health by reinforcing hydration, smoothing texture, and improving the skin’s ability to protect itself.

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.

Hydroxyethylcellulose doesn’t provide any notable skincare benefits. It’s used for formulation purposes. It’s a very effective emulsifier and thickening agent. It also improves the product’s texture and feel. It allows manufacturers to use less surfactant making the product safer for your skin.

It’s safe but can irritate sensitive skin sometimes. Pay attention to concentration!

Xanthan Gum is used as a thickener or rheology modifier and emulsion stabilizer. It doesn’t provide any notable skin-related effects and is used mostly for formulation purposes. It makes the product’s texture smooth and even. It’s a naturally-derived thickener. Notable fact: it can also be found in the food you eat every day, so it is 100% safe.

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.

Biotin is also known as Vitamin H or Vitamin B7. It is an amazing chemical, but only if you take it inside as a supplement. Will it work if you apply it to the skin? There is not enough scientific data that can prove its efficiency as a cosmetic component. But manufacturers say it can smooth the skin and improve the look of your hair.

Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.

It can be an irritator due to its naturally lower pH level of 2.2. But manufacturers also use it as a pH adjuster so in most cases you will not have any issues.

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.

Chlorphenesin is a popular preservative. It doesn’t provide any skin-related positive effects and is used to prevent bacterial growth inside a product. It’s a weak preservative but works much better with silicones.

Allowed concentration: no more than 0,3% for European Union countries.

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.

Sodium Benzoate doesn’t have any great skincare effects and is used for formulation purposes. It’s a corrosion inhibitor, fragrance ingredient, and preservative.
