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.

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.

Ascorbyl Palmitate is a derivative of ascorbic and palmitic acids. It's a fat-soluble form of Vitamin C. It penetrates into the skin through cell membranes. Acts as an antioxidant. Due to its antioxidant properties, it is considered a rejuvenating vitamin. Controls the production of collagen in cells. Non-irritant at neutral pH.

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.

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.

Polysorbate 80 is a formulation component. It helps the components to mix better and makes the product feel smooth on the skin.

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.

Sodium Benzoate doesn’t have any great skincare effects and is used for formulation purposes. It’s a corrosion inhibitor, fragrance ingredient, and preservative. It is not a broad-spectrum preservative and it’s used with other preservatives for good efficiency. It’s safe, but people with eczema or a history of skin allergies should use this component with attention.

Decyl glucoside is a surfactant. It provides degreasing and wetting effects. It removes dirt and sebum gently. It doesn’t irritate the skin but at the same time, it’s an effective cleanser. It’s considered to be the safest among all the other surfactants.

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.

Ethylhexylglycerin makes the skin softer, smoother and more hydrated. It acts deeply but without any heavy or sticky feeling. In haircare products, it works as a conditioner and scalp cleanser. It is safe but only in concentration below 8% in rinse-off products and below 2% in leave-on products. Can be an irritator in higher concentrations. In general, this component is great if you see it somewhere at the bottom of the list.

Sodium PCA is a nice moisturizer and skin softener. It contains amino acids and Sodium Hyaluronate. It’s part of the Natural Moisturizing Factor (NMF) that is responsible for keeping the outer layer of the skin hydrated. If you don’t have enough NMF you can face dryness even if you don’t have other skin problems.

Caprylyl Glycol is a vey popular skincare ingredient. It makes the product spread better and feel better on your skin. It’s a preservative and it improves the effect of other preservatives. It’s also a humectant which helps to retain water. It’s good for keeping your skin in good shape. But manufacturers use it as a supporting component rather than the main one.

Hexylene Glycol is mostly used for formulation purposes. It’s a good surfactant, emulsifier, and viscosity-reducing agent. It maintains the density of the formulation of the product preventing it from separating. It also makes the product feel better.

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.

Sodium Citrate is a water-soluble soft organic surfactant with strong stabilizing and conditioning effects. It helps to produce foam and lowers the negative impact of hard water on your skin and hair. It also helps to regulate the pH level of the product. It’s a natural ingredient and it’s safe for most people. It’s used in food (additive number E331).

Cetyl Alcohol is a fatty alcohol. It’s responsible for making your skin soft and improving product thickness. It makes the product easier to apply and feel richer. Though it contains the word “Alcohol” in its title, the component doesn’t belong to harmful alcohols. That’s why a product with this component can still be marked as Alcohol-free. Usually, manufacturers receive this component from coconut or palm oil.

Dipropylene Glycol is a solvent, emulsifier, viscosity decreasing, and masking agent. It helps to extract useful chemicals from plants and leaves, making natural components in a product more effective. It also helps to hydrate the skin. Considered safe for health and doesn't irritate the skin in common concentration.

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.

Tocopherol is one of the most popular active ingredients in cosmetics. It’s a brilliant component. It's a form of Vitamin E and it does help the skin and hair a lot. It conditions the skin, strengthens its barrier, protects it against harm, and makes the tone even. It also helps your skin and hair to resist the sun. It’s safe but can irritate sensitive skin sometimes. Pay attention to concentration!

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.

Behenyl Alcohol is an emulsifier. It makes the product feel softer and more pleasant to touch. It also provides an anti-inflammation effect. Made of natural ingredients and can be seen in organic products a lot.

Glyceryl Stearate SE is a nice moisturizing ingredient. It hydrates the upper layers of the skin and fills small wrinkles. In haircare products, it's used for making hair softer.
