Ceramides in Skincare: What They Are and How They Support the Skin Barrier

Last Reviewed: August, 2026

Ceramides are naturally occurring lipids found in the outer layer of the skin. As a key component of the skin barrier, they help support moisture retention and hydration, contributing to skin that feels comfortable and well-conditioned¹. When Ceramide levels decline, the skin may become more prone to dryness, tightness, and roughness².

In this article, we explain what Ceramides are, how they support the skin barrier, their potential benefits for skin, and how Ceramide-containing skincare can be incorporated into your daily routine.

Ceramides are lipid molecules naturally found in the stratum corneum, the outermost layer of the skin. As a key component of the skin’s lipid matrix, alongside cholesterol and fatty acids, they help maintain cohesion between skin cells and support the skin barrier. This structured lipid layer helps reduce water loss, maintain hydration balance, and support the skin’s natural protective function⁴.

Ceramides are a family of lipid molecules that differ in structure and function. More than a dozen types are naturally present in the skin, where they contribute to the organisation and stability of the skin’s lipid barrier⁴. In skincare formulations, specific Ceramides are selected for their ability to help support this natural lipid structure and maintain barrier function.

• Ceramide NP (Ceramide 3) - can help support moisture retention and barrier integrity. It is widely used in skincare formulations designed to help maintain hydration in the outer layers of the skin and support overall barrier function⁵.
• Ceramide AP (Ceramide 6) - can help support smoother skin texture and barrier function. It is often combined with other Ceramides to help support the skin’s surface condition and maintain lipid balance within the outer skin layers⁵.
• Ceramide EOP (Ceramide 1) - can help support lipid organisation within the skin barrier. It contributes to the structured arrangement of lipids in the outer skin layer, which is important for maintaining barrier stability⁵.

Ceramides used in skincare can be derived from natural sources or produced synthetically, although most dermatological formulations use skin-identical synthetic Ceramides.

Naturally derived Ceramides:

• Obtained from plant or animal lipid sources.
• Composition may vary depending on the raw material.
• Less commonly used in controlled dermatological skincare systems⁶.

Synthetic (skin-identical) Ceramides:

• Produced in laboratories but structurally identical to those found in human skin.
• Highly stable and consistent in quality.
• Commonly used in dermatological formulations due to predictable performance⁷.

As a result, skin-identical synthetic Ceramides are widely used in dermatological skincare formulations due to their stability and consistency.

Ceramides play a key role in maintaining the skin’s lipid barrier, helping to keep the outer layer structured and cohesive. By supporting this barrier function, they may help reduce moisture loss and maintain hydration within the skin, contributing to overall skin comfort, particularly in dry or moisture-depleted skin¹⁸.

Ceramide-containing skincare is generally suitable for all skin types, as Ceramides are naturally present within the skin’s lipid barrier. It may be particularly beneficial for skin that is experiencing a loss of moisture balance or a weakened skin barrier, which can contribute to dryness and discomfort¹.

It may be especially suitable for skin that is:

• Dry or rough-feeling, where the skin may feel tight or uncomfortable¹.
• Exposed to environmental stressors, such as cold weather, wind, or low humidity.
• Prone to moisture loss, where the skin may feel dehydrated or less resilient.
• Frequently cleansed or washed, which may affect the skin’s natural lipid balance.
• Eczema-prone, where the skin barrier may be more sensitive and susceptible to moisture loss⁹.

Ceramide levels within the stratum corneum may naturally decline over time due to a combination of intrinsic and external factors that affect the skin’s lipid balance. As Ceramide levels change, the skin barrier may become less efficient at retaining moisture and maintaining optimal hydration¹⁰. Factors that may contribute to reduced Ceramide levels include:

• Environmental stress, such as cold, wind, or low humidity.
• Frequent cleansing or over-washing, which may remove surface lipids.
• Natural skin changes over time that affect lipid composition.

Ceramides are typically found in leave-on skincare products such as moisturisers, where they help support the skin’s natural protective barrier and maintain moisture levels. They are usually applied after cleansing as part of a consistent skincare routine to help reduce moisture loss and support overall skin comfort.

A simple daily routine may include:

• Gently cleansing the skin to help remove impurities while maintaining the skin’s natural barrier.
• Applying hydrating ingredients such as Humectants (for example, Urea or other moisture-binding components) to help increase water content in the outer skin layers.
• Using a Ceramide-containing moisturiser to help support the skin’s lipid matrix and help reduce transepidermal water loss.

Eucerin formulations containing Ceramide 3 are developed to support dry and moisture-depleted skin. These products combine Ceramides with Urea and Natural Moisturising Factors (NMFs) to help support hydration and maintain the skin’s barrier function.

They can be used across different areas of the body depending on skin needs:

Body care:

Eucerin UreaRepair PLUS: 10% Urea Body Lotion: For very dry, rough skin, this body lotion contains Urea, Ceramide 3, and NMFs. It provides immediate relief from dryness and helps support long-lasting hydration for up to 72 hours, while helping to protect the skin from external irritants.

Targeted care for hands and feet:

Eucerin UreaRepair Plus 5% Urea Hand Cream: Fragrance-free and fast-absorbing with no greasy residue, this hand cream contains Urea, Ceramide 3, and NMFs. It provides immediate relief from dryness and helps support long-lasting hydration for up to 48 hours, while helping to support the skin’s natural barrier.

Eucerin UreaRepair Plus 10% Urea Foot Cream: Fast-absorbing and non-greasy, this foot cream contains Urea, Ceramide 3, and NMFs. It provides immediate and intensive moisturisation for up to 48 hours and helps support the skin’s natural lipid barrier, helping to reduce dryness and soften rough, cracked heels.

Face care:

Eucerin UreaRepair Replenishing Face Cream 5% Urea: For very dry skin, this fast-absorbing face cream provides intensive hydration for up to 48 hours. Containing Urea, Ceramide 3, and NMFs, it helps reduce the feeling of tightness and supports smoother, more comfortable-looking skin. It is suitable for use under makeup or after shaving.

Eucerin UreaRepair Rich Replenishing Face Cream 5% Urea: Designed for very dry, tight skin, this night cream contains Urea, Ceramide 3, and NMFs. It provides intensive overnight hydration, helping to reduce the feeling of tightness and leave skin feeling soft, smooth, and more comfortable by morning.

Ceramides are often used alongside other skincare ingredients that support hydration and skin comfort through different but complementary mechanisms. When combined, these ingredients can help support the skin’s moisture balance and barrier function more effectively than when used alone¹¹.

Ceramides are commonly combined with ingredients that help support hydration and skin comfort in different ways.

• Hyaluronic Acid: Hyaluronic Acid helps attract and retain water in the skin¹², while Ceramides help reduce moisture loss by supporting the skin’s lipid barrier. Together, they may help support long-lasting hydration and more comfortable-looking skin.
• Urea and NMFs: Urea helps bind water within the skin, while Natural Moisturising Factors (NMFs) support the skin’s natural hydration processes¹³. Ceramides help support the skin’s lipid barrier, helping to maintain hydration balance in dry or moisture-depleted skin.
• Peptides: Peptides are used in skincare to support skin conditioning, while Ceramides help support the skin’s lipid barrier¹⁴. Together, they may help support overall skin comfort and a smoother-looking appearance.

Ceramides are essential lipids found in the skin’s outer layer that may help maintain the skin’s moisture balance and support the integrity of the skin’s natural barrier. In skincare formulations, they are often combined with ingredients such as Urea and Natural Moisturising Factors (NMFs) to help support dry or moisture-depleted skin. Regular use of Ceramide-containing skincare can help improve the skin’s comfort and leave it feeling smoother and more hydrated over time.
