Overview
- One of the main ceramides found naturally in the skin's outer barrier
- Supports the skin barrier and reduce moisture loss
- Commonly used for concerns related to dryness, tightness, and a weakened skin barrier
Ceramide NP: Why it Matters
What is ceramide NP, and why do people use it?
Ceramides are a type of lipid that the skin naturally produces. They sit between the cells of the skin's outermost layer, much like mortar between bricks, and make up a significant portion of the lipids in this layer. Ceramide NP is one of the types of ceramide naturally found in human skin and is widely used in skincare products. It is commonly used to support skin that feels dry, tight, rough, or uncomfortable, particularly when the skin barrier has been weakened.
How does ceramide NP actually work on the skin?
PDRN consists of DNA fragments that are thought to interact with pathways involved in skin repair and renewal. These interactions help support the skin's natural processes and contribute to a smoother, more supple-looking appearance over time. In topical skincare, how effectively PDRN interacts with the skin can vary depending on factors such as molecular size, formulation, and delivery method.
Why put back a ceramide the skin already makes?
The skin's ceramide levels can change over time. Aging, seasonal changes, and frequent or harsh cleansing can affect the skin's lipid composition and barrier function. As these changes occur, skin may become more prone to dryness and moisture loss. Applying ceramide NP helps supplement the ceramides naturally found in the skin, supporting the barrier and helping maintain its ability to retain moisture.

✓ Dry or Flaky Skin
-
-
Suitable for skin that feels tight, rough, or looks flaky. Ceramide NP improve moisture retention, leaving the surface feeling softer and more comfortable.
- ✓ Sensitive or Easily Reactive Skin
Recommended for skin that stings, feels uncomfortable, or becomes irritated easily. Supporting the skin barrier can improve the skin's ability to withstand everyday stressors.
-
✓ Mature Skin
Ideal for skin that has become drier or less resilient with age. Ceramide NP helps maintain a smoother and more supple-looking appearance.
Practical Usage Tips
Q. Can ceramide NP be used alongside retinol or exfoliating acids?
A. Yes. Ceramide NP is a barrier-supporting ingredient and is generally well tolerated alongside stronger active ingredients. Applying a moisturizer containing ceramide NP after retinol or exfoliating acids can help support the skin barrier and reduce the dryness or discomfort that may occur when using these ingredients.
Q. How often should you use a ceramide NP product?
A. Ceramide NP is gentle enough for daily use, both morning and evening. It can also be used year-round, particularly during colder or drier seasons when the skin may lose moisture more easily. Unlike ingredients that require gradual introduction, ceramide NP does not generally need to be built up over time and can be incorporated into a daily skincare routine
Did you know?
Ceramides were first studied in brain tissue before their important role in the skin was fully understood. The name "ceramide" comes from the Latin word cerebrum, meaning brain, reflecting their early connection to lipids found in nervous tissue. Today, ceramides are widely recognized as essential components of the skin's protective barrier and are commonly used in skincare products designed to support dry and sensitive skin.
