Hudanalys

Hudanalys is the systematic evaluation of skin properties to describe its condition, functionality, and response to interventions. The term is used across dermatology, cosmetics research, and clinical skincare to refer to both qualitative assessments and quantitative measurements.

Assessments combine clinical observation with instrumental techniques. Non-invasive devices include corneometers for skin hydration, sebumeters for surface lipids, and cutometers for elasticity. Surface texture can be analysed with Visioscan, while pigmentation and colour are measured with spectrophotometers or colorimeters. Multispectral imaging provides information on vascularity and lesion characteristics, and advanced methods such as optical coherence tomography or confocal microscopy are used in research settings. Measurements are typically performed under standardized environmental conditions.

Data interpretation relies on reference values and controlled protocols; results are often given in arbitrary units or relative scales. Variability between devices, operators, and environmental conditions must be considered. Hudanalys is generally descriptive and support-based rather than a stand-alone diagnosis, with clinical judgment remaining essential.

Applications include product development, efficacy testing in cosmetics, dermatological diagnosis support, and monitoring of treatment responses. In consumer contexts, smartphone-based skin analysis apps have popularized hudanalys, though their accuracy varies and is subject to validation. Limitations include device calibration, sensitivity to external factors, and the non-diagnostic nature of most measures. See also dermatology, cosmetic science, and skin physiology.
