Correlation between a Cutometer and quantitative evaluation using Moire topography in age-related skin elasticity

Area of Science:

• Dermatology
• Biomedical Engineering
• Aesthetics

Background:

• Skin aging is characterized by reduced elasticity, dryness, and wrinkles.
• Quantifying skin elasticity is crucial for assessing aging, yet it's less visually apparent than wrinkles.
• Objective methods are needed to measure skin elasticity changes accurately.

Purpose of the Study:

• To correlate age with Cutometer parameters for skin elasticity.
• To develop and validate Moire topography for quantifying visual skin elasticity.
• To establish a link between instrumental and visual assessments of skin aging.

Main Methods:

• Correlated age with Cutometer parameters in women aged 20-61.
• Developed Moire topography to quantify visual skin elasticity using a five-grade scale.
• Utilized three specialists for consensus scoring of Moire topographic photos.
• Compared Cutometer results with Moire topography scores.

Main Results:

• Significant negative correlations found between age and Cutometer parameters (r=-0.687-0.725).
• Moire topography scores showed a strong negative correlation with age (r=-0.938).
• High correlation between sensory evaluation (Moire system) and age (r=-0.765-0.932).
• Significant positive correlation between Cutometer results and Moire topography scores (r=0.711).

Conclusions:

• Cutometer parameters R7 and R2 are key indicators for assessing skin elasticity and aging.
• Moire topography effectively quantifies visually perceived skin elasticity decline.
• Instrumental measurements correlate well with visual perception of age-related skin changes.
