Epidermal Cohesion Testing Services for Hydration Claims
What is Epidermal cohesion?
Epidermal cohesion hydration testing measures how well skin barrier proteins hold together when exposed to moisturizing ingredients, using tape stripping protocols that remove successive cell layers. Our partner labs analyze corneocyte adhesion strength through standardized desquamation measurements, typically showing 15-30% improvement in barrier integrity after 28-day product application studies.
Why do you need this service?
Cosmetic labs use epidermal cohesion hydration testing to validate moisturizer claims before launch, measuring how formulations strengthen skin barrier function and water retention. Brands rely on these tests to demonstrate measurable hydration improvements for marketing claims, while ingredient suppliers use the data to showcase raw material performance in final formulations.

Epidermal Cohesion Testing for Hydration Product Validation
Epidermal cohesion testing measures how well your hydration products strengthen the skin’s barrier function and intercellular connections. This specialized assessment goes beyond basic moisture measurements to evaluate how formulations improve skin integrity at the cellular level.
Barrier Function Assessment Methods
Labs use multiple approaches to evaluate how your products affect skin cohesion and barrier strength. Transepidermal water loss (TEWL) measurements track moisture retention improvements, while tape stripping tests assess stratum corneum adhesion changes.
Key testing parameters include:
- Corneocyte cohesion strength measurements
- Intercellular lipid organization analysis
- Desquamation rate monitoring
- Barrier recovery time assessment
Clinical Validation Protocols
Professional testing facilities run controlled studies to validate your hydration claims with measurable data. These protocols typically span 2-8 weeks and include baseline measurements, product application periods, and recovery assessments.
Standard validation includes:
- Pre-treatment skin condition documentation
- Daily application monitoring with biophysical measurements
- Post-treatment barrier function evaluation
- Statistical analysis for regulatory submissions

Practical Applications of Epidermal Cohesion Hydration Testing
Epidermal cohesion hydration testing applications provide brands with quantifiable data on how skincare formulations impact skin barrier integrity and moisture retention capacity.
Anti-Aging Product Development
Labs measure epidermal cohesion changes before and after applying serums, creams, and treatments targeting mature skin concerns. These tests reveal how peptides, retinoids, and hydrating compounds affect skin’s structural integrity over 24-48 hour periods.
Testing protocols include tape stripping methods and corneometer readings to assess barrier function improvements. Results show percentage increases in hydration levels and reduced transepidermal water loss, giving brands concrete efficacy claims for marketing materials.
Sensitive Skin Formulation Validation
Cosmetic labs evaluate gentle formulations designed for reactive or compromised skin barriers through controlled cohesion testing. Teams apply products to volunteers with sensitive skin conditions and monitor irritation markers alongside hydration metrics.
Testing includes pH monitoring, electrical conductance measurements, and visual assessments over 72-hour periods. Data helps brands demonstrate non-irritating hydration benefits while maintaining product safety profiles for sensitive consumer segments.
