Objective Apparent Age Score Model for Skin Aging Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing skin aging are subjective, making it difficult to evaluate the effectiveness of anti-aging products and compare deteriorative effects across individuals, as they rely on variable social norms and expectations rather than objective measurements.
Innovation Solution
Development of an Objective Apparent Age Score (OAAS) model using a combination of clinical, biophysical, and biochemical parameters, measured through instrumentation and expert clinician assessment, to provide a consistent and repeatable quantification of skin aging, accounting for the majority of observable skin aging in a defined population.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subjective apparent age assessment methods are used, then social norms and expectations are incorporated into the evaluation, but consistency and repeatability of measurements deteriorate
Solution Approach 1:
The patent segments the apparent age assessment into multiple independent objective parameters (skin texture, elasticity, pigmentation, vascular patterns, etc.) that can be measured separately using different instrumentation methods. This segmentation allows each parameter to be measured with high precision while the combination of parameters provides a comprehensive assessment that adapts to individual variations.
Solution Approach 2:
The patent creates a universal assessment framework that can be applied across different populations and conditions. The multi-parameter objective model serves multiple functions: it provides consistent measurements for research, enables comparison across studies, supports product efficacy evaluation, and adapts to different demographic groups through statistical modeling.
2Measurement precision
If multiple parameters are measured to improve objectivity, then measurement consistency improves, but device complexity and measurement time increase
Solution Approach 1:
The patent merges multiple measurement modalities (optical imaging, spectroscopy, topography) into an integrated assessment system. By combining data from different instruments and merging them into a unified statistical model, the system achieves high objectivity without requiring each individual device to be overly complex.
Solution Approach 2:
The patent transforms complex biological aging processes into measurable physical and optical parameters. By changing the parameters from subjective visual assessments to quantifiable metrics (reflectance, absorbance, surface roughness, etc.), the system achieves objectivity while using relatively simple instrumentation.
3Measurement precision
If comprehensive clinical, biophysical, and biochemical parameters are measured, then the accuracy of apparent age assessment improves, but the time and resources required for measurement increase
Solution Approach 1:
The patent performs preliminary data processing and parameter selection before final assessment. By pre-identifying the most relevant parameters through statistical analysis and preparing measurement protocols in advance, the system reduces actual measurement time while maintaining comprehensive assessment accuracy.
Solution Approach 2:
The patent uses optical imaging and spectroscopy to create copies or representations of skin properties without requiring direct biochemical analysis. These optical copies provide sufficient information for accurate aging assessment, eliminating the need for time-consuming laboratory biochemical tests.

AI summary
Methods of developing equations for objectively assigning or predicting an apparent age are disclosed. Advantageously, the equations of objective apparent age may be based on a relatively small number of critical parameters combined in a way that accounts for all or most of the apparent skin aging in a defined population or sub-population. Despite the relatively small data collection requirements, the present invention includes an objective model of apparent age that is useful for evaluation of products, useful for predicting treatment outcomes and useful for predicting the effects of deteriorative factors. The formalization of an Objective Apparent Age Score allows one to identify the biophysical and biochemical parameters that mostly influence an individual's apparent age, and can be used to select specific anti-aging treatments with increased chances of visible success. The Objective Apparent Age Score may also be used to support marketing claims.
