Summary
This study found a significant correlation between skin roughness and dermal density, particularly dermal thickness. Ultrasonography and transparency profilometry are useful for wrinkle evaluation.
Area of Science:
- Dermatology
- Biophysics
- Medical Imaging
Background:
- The replica method for skin smoothness estimation has limitations due to potential roughness differences.
- Observing dermal layer changes is crucial for accurate wrinkle evaluation.
- Ultrasonic display equipment is commonly used for dermal layer assessment.
Purpose of the Study:
- To investigate the correlation between skin roughness and dermal density.
- To evaluate the utility of ultrasonography in conjunction with transparency profilometry for wrinkle assessment.
Main Methods:
- Evaluated crow's feet in 95 Korean females using Skin-Visiometer SV 600 (transparency profilometry) and Dermascan C (high-frequency ultrasonography).
- Skin-Visiometer analyzes a thin skin print using parallel light.
- Dermascan C provides non-invasive evaluation of skin thickness and echo density.
Main Results:
- A correlation was found between skin roughness and dermal density.
- Significant correlation observed between skin roughness (R2) and dermal thickness.
- Significant negative correlation found between dermal density and dermal thickness (P<0.05).
Conclusions:
- Ultrasonography systems, combined with transparency profilometry, show promise as valuable tools for wrinkle evaluation.
- Further research is needed to fully establish the role of these methods in dermatological assessments.
