🧴 Filaggrin: A Key Protein for Skin Hydration and Barrier Integrity

Healthy, hydrated skin starts long before the application of a cosmetic product—it begins within the epidermis.

Filaggrin is a key structural protein that plays a central role in maintaining the skin barrier. By organizing keratin filaments, it strengthens the epidermis, while its natural degradation generates Natural Moisturizing Factors (NMFs) that help retain water and keep the skin hydrated.

Because of these essential functions, filaggrin has become an important biomarker in both dermatology and dermo-cosmetic research.

🩺 A valuable biomarker for skin research

Reduced filaggrin expression is associated with impaired barrier function and skin disorders such as atopic dermatitis. Assessing its expression provides valuable insights into skin physiology and the effects of therapeutic or cosmetic interventions.

💄 Supporting innovation in dermo-cosmetics

Filaggrin immunostaining is widely used to evaluate moisturizers, barrier-repair formulations and active ingredients designed to improve skin hydration and epidermal integrity.

🔬 How Atlantic Bone Screen can help

The images showcase filaggrin immunohistochemistry performed by our histology team:

➡️ Left: Original filaggrin staining, showing its localization mainly within the granular and cornified layers of the epidermis.

➡️ Middle: Digital color deconvolution isolates the specific filaggrin signal (highlighted in red), improving visualization and enabling objective image analysis.

➡️ Right: Automated quantification of the filaggrin-positive area (yellow), providing robust and reproducible measurements for preclinical dermatology and dermo-cosmetic studies.

While filaggrin is highlighted here, the same optimized workflow can be applied to other skin biomarkers. From tissue processing, immunohistochemistry and digital slide scanning to automated image analysis and quantitative readouts, Atlantic Bone Screen delivers standardized, high-quality data to support preclinical dermatology and dermo-cosmetic research and thus accelerate the development of tomorrow’s skincare and dermatology innovations worldwide.
