Ceramides in Cosmetics: The "Core Ingredient" for Skin Barriers & Systematic Solutions

In skin science research, ceramides are universally recognized as the core molecules maintaining the structure and function of the skin barrier. As early as 1983, Professor Elias proposed the classic "brick-and-mortar structure model," which clearly reveals the microscopic composition of the stratum corneum: keratinocytes act as "bricks," while intercellular lipids serve as the key "mortar" that tightly binds the cells together. Among these lipids, ceramides account for approximately 50%—a proportion far higher than cholesterol and free fatty acids—establishing their irreplaceable foundational role.

This structure defines a core mechanism: the content and compositional structure of ceramides directly govern the integrity of the skin barrier, the skin's moisturizing capacity, and its resistance to external stimuli. When the total ceramide content decreases or the ratio of various subtypes becomes imbalanced, transepidermal water loss (TEWL) increases significantly, and the skin subsequently succumbs to a series of barrier dysfunction states such as dryness, sensitivity, and increased susceptibility to inflammation.

Ceramides: A "Family" of Compounds, Not a Single Ingredient

In the natural skin environment, ceramides are not a single component but a functional system composed of multiple structural subtypes. Different ceramides play unique roles in skin barrier construction, stratum corneum stability, and skin tolerance regulation. This means that relying solely on a single type of ceramide is often insufficient to fully meet the skin's needs or enhance the complex system of the skin barrier.

Viablife’s Solution: A Systematic Portfolio Based on Human-Homologous Structures

Built on cutting-edge insights into skin science, Viablife has developed a systematic product portfolio centered on human-homologous ceramides, focusing on three core series to precisely address diverse R&D requirements.

High-Purity Series: The Scientific Choice Matching Human Skin Structure

 Designed specifically for the development of high-end products pursuing high ingredient purity, exceptional structural consistency, and flexible formulation applications, this series comprehensively covers the main ceramide types naturally present in human skin:

• Viablife Ceramide NP (Recommended addition level: 0.1–5%)

• Viablife Ceramide AP (0.1–2%)

• Viablife Ceramide EOP (0.1–2%)

• Viablife Ceramide NG (0.1–19%)

• Viablife Phyto-S (0.2–2%)

• Viablife TAPS (0.2–2%)

All products in this series emphasize high structural homology with human skin ceramides, providing a solid and reliable raw material foundation for barrier repair, tolerance enhancement, and core efficacy realization in functional skincare formulations.

This series is particularly suitable for:

• Precise development of high-end functional skincare formulations

• Compound research requiring exact control over ceramide types and ratios

• Quality-oriented products with strict standards for raw material traceability, purity, and structural consistency

Microcapsule Series – A Solution for High Activity and Stability

To address core technical pain points of ceramides in formulations—such as poor water solubility, limited oil solubility, and low chemical stability—Viablife has developed the Microcapsule Series. This technology encapsulates ceramides in protective wall materials, significantly enhancing their activity and durability in final products.

Representative Product: Viablife Ceramide 50 (Recommended Addition Level: 0.2–10%)

Core Product Features:

• High Active Content: Ceramide active ingredient content exceeds 50%

• Easy Application: Simplified formulation with ready-to-use design, greatly reducing process complexity

• Safe and Pure: Preservative-free, meeting the demand for minimalistic formulations

• Broad Process Compatibility: Suitable for various production processes such as cold mixing and hot processing

Multiple Ceramide Series – Deeply Enhancing the Skin Barrier

 This series consists of compound ceramide products scientifically formulated based on the natural lipid composition of the skin and the principle of synergistic effects, aiming to provide an all-in-one barrier repair solution.

Representative Products:

• Viablife CeraMix Plus (Recommended Addition Level: 0.5–20%): High active content (>30%) with a classic 1+3+6 ceramide combination. Single addition achieves multi-type synergy with stable systems, ideal for formulations requiring efficient development.

• Viablife CeraMix I (Recommended Addition Level: 0.5–20%): Bionically designed according to the natural ratio of the skin barrier, containing a four-ceramide combination to specifically strengthen the barrier structure. Tailored for products targeting barrier-damaged skin, sensitive skin repair, and long-term maintenance.

This series is particularly suitable for:

• Rapid projects needing shortened R&D cycles

• Minimalistic formulations aiming to reduce raw material complexity

• Product lines centered on skin barrier repair and tolerance enhancement

Whether for high-end customized formulations or functional products requiring rapid market launch, Viablife’s full range of ceramide products delivers highly compatible, stable, and flexible application solutions. This transforms ceramides from "conceptual additives" in formulations into core functional ingredients, unlocking their multi-dimensional efficacy, cost-effectiveness, and broad application potential in serums, creams, barrier repair products, and more.

With a comprehensive product matrix and systematic technical support, Viablife is transforming ceramides from "difficult-to-master star ingredients" into "practical foundational raw materials that truly solve problems."

Conclusion

The value of ceramides is rooted in skin science, and the full release of their potential relies on continuous technological and systematic innovation.

From large-scale independent production of key precursors to one-step full fermentation processes and diversified ready-to-use products, Viablife is building a systematic, implementable, and sustainable ceramide product solution. This not only reflects a profound understanding of skin barrier science but also effectively addresses the core needs of the entire industry in formulation practice.
