Overview
The CK Visioline VL650 Skin Wrinkle Analysis System is a non-invasive, optical profilometry instrument engineered for quantitative assessment of skin surface topography—specifically wrinkle depth, length, area, and volume. It operates on the principle of shadow projection profilometry: a precisely collimated, oblique light beam illuminates a silicone replica (impression) of the skin surface; surface relief features—including wrinkles—cast geometrically defined shadows proportional to their depth and orientation. A high-resolution monochrome CCD camera, positioned perpendicular to the sample plane, captures the shadow pattern with sub-pixel spatial fidelity. This optical configuration eliminates reliance on direct contact or laser scanning, ensuring measurement repeatability independent of operator technique and minimizing inter-subject variability in clinical and cosmetic research settings.
Key Features
- Optimized shadow projection geometry with fixed 30° illumination angle and calibrated light intensity for consistent contrast generation across diverse skin tones and silicone impression qualities.
- 12-megapixel progressive-scan CCD sensor with 4.5 µm pixel pitch, enabling resolution down to 8 µm per image pixel at standard working distance (100 mm).
- Dedicated motorized stage with XYZ precision positioning (±1 µm repeatability) for automated multi-site acquisition across large-area silicone replicas (up to 50 × 50 mm).
- Integrated LED-based uniform illumination source with thermal stabilization, ensuring stable photometric output over extended acquisition sessions (>8 hours continuous operation).
- Modular hardware design compliant with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity), suitable for installation in ISO 17025-accredited dermatological testing laboratories.
Sample Compatibility & Compliance
The VL650 is validated for use with standardized medical-grade silicone impression materials (e.g., President Jet, Zhermack Hydrogum) cured under controlled humidity (40–60% RH) and temperature (20–25°C). It supports analysis of both static (baseline) and dynamic (time-series) impressions collected pre- and post-intervention in double-blind, randomized controlled trials. Data outputs comply with ISO 13097:2012 (“Cosmetics — Methods of analysis — Assessment of anti-wrinkle efficacy using skin replicas”) and align with ASTM E2955-14 guidelines for digital image-based topographic quantification. The system architecture enables full audit trail functionality required for GLP-compliant studies and satisfies data integrity criteria outlined in FDA 21 CFR Part 11 when deployed with validated software version 5.2 or later.
Software & Data Management
The Visioline Analysis Software (v5.2.1) provides fully traceable image processing workflows: automatic shadow edge detection via adaptive thresholding, curvature-based wrinkle segmentation, and ISO-defined morphometric parameter extraction (e.g., Wrinkle Area Index, Mean Depth, Total Length, Volume Density). All raw images, processed masks, and numerical results are stored in vendor-neutral TIFF and CSV formats. Metadata—including operator ID, calibration timestamp, environmental log (temperature/humidity from optional external sensors), and instrument firmware revision—is embedded in XMP sidecar files. Export modules support direct integration with SAS, R, and Python-based statistical platforms via ODBC and REST API interfaces. Software validation documentation (IQ/OQ/PQ protocols) is available upon request for regulated environments.
Applications
- Evaluation of topical anti-aging actives (retinoids, peptides, antioxidants) in Phase II/III cosmetic clinical trials.
- Comparative benchmarking of dermal filler performance across timepoints (D0, D30, D90) using volumetric wrinkle reduction metrics.
- Objective endpoint quantification in regulatory submissions to Health Canada, ANVISA, and ASEAN Cosmetic Directive authorities.
- Longitudinal monitoring of intrinsic aging progression in cohort studies, including photoaged vs. chronologically aged skin stratification.
- Validation of non-invasive imaging modalities (e.g., OCT, confocal microscopy) against gold-standard replica-based reference measurements.
FAQ
What silicone impression material is recommended for optimal VL650 performance?
CK recommends President Jet Soft Light Body or Zhermack Elite HD+ due to their low shrinkage (2.5 MPa), and consistent surface detail reproduction under standardized curing conditions.
Can the VL650 analyze live skin without silicone impressions?
No—the VL650 is designed exclusively for ex vivo analysis of stabilized silicone replicas. Real-time in vivo topography requires alternative technologies such as fringe projection or laser scanning profilometry.
Is remote software support and calibration verification available?
Yes—CK offers annual remote calibration verification via encrypted image upload and NIST-traceable reference target analysis, with certificate issuance compliant with ISO/IEC 17025 requirements.
Does the system meet EU MDR requirements for Class I medical devices?
The VL650 is classified as a Class I non-invasive device under Regulation (EU) 2017/745 and bears CE marking for “performance evaluation of cosmetic products”; it is not intended for diagnostic or therapeutic use.
