What is it?

Ceramides are the main lipid constituent of the stratum corneum of the epidermis. This is a heterogeneous and complex group of sphingolipids with differences in the length and type of their molecular chains. The skin lipid content is in fact composed of free fatty acids, cholesterol, and ceramides: these play an essential role in structuring and maintaining water permeability and contributing to the skin barrier, which is essential for healthy skin.

What is it for?

Most skin disorders (atopic dermatitis, rosacea, eczema) that involve impaired barrier function exhibit a reduction in total ceramide content.

Specifically, ceramides:

  • Contribute to the function of  the skin barrier, keeping it intact 
  • Limit water loss (TEWL: transepidermal water loss), supporting hydration
  • Combat skin aging and help maintain  elastic skin
  • Protect against external agents, reducing the risk of sensitization

What are the essential ceramides

In the rich world of lipids that make up the epidermal barrier, ceramides play a primary role in the health and integrity of the skin. There are different types of ceramides, classified mainly based on the structure of their molecular chain. At present, science has identified 12 main types of ceramides in human skin, commonly identified by the numbers from 1 to 12 (Ceramide 1, Ceramide 2, etc.). Each type of ceramide performs slightly different functions within the skin’s lipid matrix, working together to strengthen the skin barrier and regulate hydration.

The essential ceramides are:

CERAMIDE 1 (EOS)

Promotes cell cohesion, strengthening the epidermal barrier for smooth, firm skin.

CERAMIDE 2 (NS)

Helps restore and maintain the skin’s barrier function, increasing hydration.

CERAMIDE 3 (NP)

Known for its ability to deeply hydrate, it helps counter signs of aging and keep skin soft and elastic.

CERAMIDE 5 (AS)

Plays a key role in the structure of the skin barrier, ensuring an effective defense mechanism.

CERAMIDE 6 (AP)

Mainly responsible for natural exfoliation and the regulation of cell turnover, for smoother, more even skin.

It is interesting to note that the concentration and specific balance of these types of ceramides can vary depending on age, skin type, and can be affected by dermatological conditions.

This is why skincare products enriched with a balanced mix of different types of ceramides are particularly effective: they aim to restore the skin’s optimal lipid profile, compensating for specific deficiencies and more fully supporting the functions of the skin barrier.

Why it is important to use a ceramide cream

Using a cream rich in ceramides is a strategic move for anyone looking to care for their skin effectively, especially for those who have noticed signs of skin dryness, premature aging, or a loss of skin firmness. Since ceramides are a key component of the skin’s lipid barrier, external supply through a cream helps to strengthen that barrier, allowing the skin to retain moisture better and protect itself against external irritants. As a result, a ceramide cream not only softens and hydrates, but also prepares the skin to defend itself better against environmental damage such as pollution and temperature swings, which can accelerate the aging process. In addition, adding ceramides to your skincare routine can be especially beneficial in colder seasons, when skin is often exposed to conditions that can compromise its integrity.

Products with Ceramides

Formulas containing ceramides can be extremely useful for you, regardless of your Skin type. If you have Dry skin or sensitive skin, they are an absolute must-have in your skincare routine (especially during winter). Ceramides can be added to a wide range of different skincare product types such as face creams o corpo, serums, masks, and cleansers.
