Allantoin usually doesn’t catch too much attention, but it is an essential ingredient for sensitive, dry, and problem skin. It is a good moisturizer that makes skin hydrated. But manufacturers love it because of its strong soothing effect. It also exfoliates dead cells, stimulates recovery of your skin, and helps to protect the skin from the sun, frost, and similar negative impacts.

The component is researched very well and its soothing activity is confirmed by scientists. Used in concentration between 0.5-2%.

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.

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.

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.

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.
