Ceramides make up to 50% of the skin's natural barrier and are essential for healthy, hydrated skin. As a naturally occurring substance in the body, they are exceptionally well-tolerated and show impressive results even at low concentrations.
What are ceramides?
Ceramides belong to the group of sphingolipids and are natural components of the outermost layer of skin, the stratum corneum. These complex lipid molecules act as biological mortar between skin cells and, together with cholesterol and free fatty acids, form the vital skin barrier. The structure resembles a brick wall: the skin cells are the bricks, and the ceramides are the mortar between them.
Science distinguishes over twelve different types of ceramides, with ceramides NP, AP, and EOP being the most commonly used in cosmetics. Each type has specific properties: ceramide NP strengthens the barrier function, ceramide AP improves skin elasticity, and ceramide EOP binds the skin layers firmly together. With increasing age, the body's own ceramide production declines drastically—by about 1% annually starting as early as age 20.
Modern biotechnology makes it possible to synthesize bioidentical ceramides, which are structurally identical to the skin's own ceramides. This breakthrough revolutionized skincare, as synthetic ceramides exhibit the same efficacy as the body's own, but are more stable and less expensive to produce.
This is how ceramides work on your skin
Skin barrier repair and strengthening
Ceramides repair damaged skin barriers by integrating into the lipid bilayers of the outermost layer of skin. A study by Mao-Qiang et al. in the Journal of Investigative Dermatology (1995) showed that topically applied ceramides reduced transepidermal water loss by up to 21%. The molecules literally fill the gaps between skin cells and restore the skin's natural protective function.
Intensive hydration
By strengthening the skin barrier, ceramides prevent uncontrolled water loss from the skin. At the same time, they draw moisture from deeper skin layers to the surface. Clinical studies have demonstrated a 35-50% increase in hydration after four weeks of using ceramide-containing products (Coderch et al., American Journal of Clinical Dermatology, 2003).
Anti-aging through structural preservation
With age, the concentration of ceramides in the skin decreases, leading to dryness, wrinkles, and loss of elasticity. External ceramide supplementation can slow this process. Research by Imokawa et al. (Journal of Cosmetic Dermatology, 2009) showed that regular ceramide application increases skin thickness and reduces wrinkle depth.
Soothing relief for skin irritations
Ceramides have anti-inflammatory and soothing effects on irritated skin. They reduce the release of inflammatory mediators and stabilize sensitive skin reactions. Ceramide therapies show remarkable success in relieving the symptoms of eczema and atopic dermatitis.
Protection from environmental influences
An intact, ceramide-rich skin barrier provides more effective protection against harmful environmental factors such as UV radiation, air pollution, and aggressive chemicals. Studies demonstrate a significant reduction in oxidative skin damage with regular ceramide use.
Who are ceramides suitable for?
| skin type | fitness | Advantages |
|---|---|---|
| Dry skin | Excellent | Intensive hydration, barrier repair |
| Sensitive skin | Very good | Calming, protection from irritation |
| Mature skin | Very good | Anti-aging, elasticity enhancement |
| Normal skin | Good | Preventive protection, moisture retention |
| Oily skin | Conditional | Only in simplified formulations |
| Problem skin/acne | Good | Repair after treatments |
Integration into your K-Beauty routine
Application time: Ceramides are suitable for both morning and evening routines. In the evening routine, they can optimally develop their repairing properties, while in the morning they act as a protective shield.
Routine step: Ceramide products are typically used as an essence, serum, or cream in the final phase of skincare. After cleansing and toning, but before sunscreen or makeup.
Combination rules: Ceramides harmonize excellently with most active ingredients. They work particularly synergistically with hyaluronic acid , niacinamide , and peptides . When combined with potent active ingredients such as retinol or AHA/BHA, ceramides can even have a calming and balancing effect.

Myths and facts about ceramides
Myth: "Ceramides clog the pores"
Fact: Ceramides are non-comedogenic and do not clog pores. As natural skin components, they are optimally tolerated and can even be helpful for blemish-prone skin, as they strengthen the skin barrier without weighing it down.
Myth: "All ceramides are equally effective"
Fact: The different types of ceramides have different functions and strengths. Ceramide NP, for example, is particularly well-suited for dryness, while ceramide EOP has a stronger texturizing effect. High-quality products combine several types of ceramides for optimal results.
Myth: "Synthetic ceramides are less effective than natural ones"
Fact: Bioidentical, synthetic ceramides are structurally identical to the skin's own ceramides and exhibit the same effectiveness. They even have advantages: They are more stable, purer, and more sustainably produced than ceramides derived from natural sources.
Frequently asked questions about ceramides
How quickly do ceramides take effect?
Initial improvements in skin hydration are often visible after just 3-5 days. However, for lasting barrier repair, you should plan for at least 4-6 weeks of regular use.
Can ceramides be combined with vitamin C?
Yes, ceramides actually enhance the positive effects of vitamin C, as they protect the skin from potential irritation. It's best to use vitamin C in the morning and ceramides in the evening.
Are ceramides safe for pregnant women?
Ceramides are completely safe during pregnancy and breastfeeding, as they are identical to substances naturally produced by the body and are not systemically absorbed.
What concentration is optimal?
Effective ceramide concentrations range between 0.1% and 2%. Higher concentrations do not necessarily offer better results, as skin absorption is limited.
Can ceramides expire or go bad?
Ceramides are relatively stable molecules, but can degrade due to heat, light, and contact with air. Products should be stored in a cool, dark place and used within the stated expiration date.
Do ceramides help with eczema and dermatitis?
Yes, studies show significant improvements in atopic dermatitis and eczema with ceramide therapy. However, it should always be used in consultation with a dermatologist.
Is it possible to use too many ceramides?
An overdose of ceramides is practically impossible, as they are naturally occurring substances in the body. However, overly rich formulations can lead to blemishes in people with very sensitive skin.
Are plant-based or synthetic ceramides better?
Synthetic, bioidentical ceramides are generally superior because they are purer, more stable, and better researched. Plant-based ceramides can provide additional nutrients but are often less concentrated.
