Ceramides (CERAMIDE)
Commonly Found In
Overview
Ceramides are a family of sphingolipid molecules that are the dominant structural component of the stratum corneum lipid matrix, comprising approximately 50% of skin barrier lipids. They play a central role in forming the 'bricks-and-mortar' structure of the skin barrier, regulating transepidermal water loss (TEWL), and maintaining the hydration and integrity of the outer skin layer. Clinical evidence indicates that ceramide deficiency is associated with atopic dermatitis, psoriasis, and dry skin conditions, and that topical ceramide-containing formulations can help restore barrier function, reduce TEWL, and improve skin hydration. Studies suggest ceramides are well tolerated by sensitive skin types, including those with barrier-compromised conditions such as eczema, as they closely mimic the skin's own lipid composition.
Also known as: Ceramide NP (Ceramide 3), Ceramide AP (Ceramide 6-II), Ceramide EOP (Ceramide 1), Ceramide NS (Ceramide 2), N-acylsphingosine, Phytoceramide (plant-derived)
Key Benefits
Clinical evidence indicates that topical ceramide formulations help restore the skin's lipid barrier, reduce transepidermal water loss (TEWL), and improve skin hydration, particularly in barrier-compromised conditions such as atopic dermatitis and xerosis. Studies suggest ceramides work most effectively when combined with other stratum corneum lipids (cholesterol and fatty acids) in physiologic ratios to optimally restore lamellar body secretion and barrier architecture.

Skin Compatibility Ratings
Comedogenic Rating
Non-comedogenic. Ceramides are endogenous skin lipids and do not contribute to comedone formation.

Irritancy Rating
Non-irritating; considered among the most skin-compatible cosmetic actives given their identity with natural skin lipids. Recommended for sensitive and atopic skin.

Typical Use Concentration
Range
0.01-1%
Optimal
0.05-0.5%
Effective at very low concentrations due to their structural role in the lipid lamellae; typically used at 0.1-0.5% in combination with other lipids. Higher concentrations do not necessarily provide proportionally greater benefit.

Research suggests a ceramide:cholesterol:fatty acid ratio of approximately 1:1:1 to 3:1:1 is optimal for barrier repair. Ceramides are compatible with virtually all cosmetic ingredients.

π Why Regulations Differ
Ceramides are endogenous skin components and are not subject to specific restrictions in any major regulatory jurisdiction (EU, US, JP, KR, UK). They are classified as standard cosmetic actives/skin conditioners. No bans, concentration limits, or pending regulatory actions exist for the ceramide class in cosmetic applications. Minor differences may arise in nomenclature requirements between jurisdictions for specific ceramide types.
Regulation Analysis
Category Comparison
97% of SKIN CONDITIONING ingredients (378 of 389) are banned in the EU, but this one is approved.
πΏ Natural Sources
Constitute 30-40% of outer skin layer (epidermis) and approximately 50% of stratum corneum lipids. Naturally synthesized by keratinocytes in epidermis via de novo pathway. Plant sources: wheat germ oil, rice bran oil, jojoba oil, hemp seed oil, macadamia oil. Oils rich in linoleic acid (borage oil) help restore ceramides.
π How It's Made
Three synthesis pathways: de novo synthesis (most important), sphingomyelin hydrolysis, and salvage pathway. Cosmetic ceramides produced synthetically or extracted from plants. Nomenclature system developed by Wertz and Downing (1983, 1985) numbered ceramides with Roman numerals. Modern classification includes Ceramide 1-9 and specific types (EOS, NP, AP, etc.).
π Uses in Cosmetics
Used at low concentrations (typically under 1%) in moisturizers, serums, and barrier repair products. Ceramides are naturally found in skin and help maintain the skin's moisture barrier. Products containing ceramides help strengthen the skin against dryness and irritation.
π¬ Other Applications
Being researched as an oral supplement for skin health. Also studied for pharmaceutical use in treating skin barrier disorders like eczema and psoriasis.
π‘ Fun Facts
- β’ Discovered over 50 years ago β early researchers nicknamed it 'Problemin' (meaning barrier) before the name 'ceramide' stuck
- β’ Scientists developed a numbering system for different types of ceramides in the 1980s that is still used today
- β’ Our bodies can't make ceramides without linoleic acid, which must come from diet or skincare β this is why it's called an essential fatty acid
