The radiofrequency (RF) device demonstrated a superior and more sustained reduction in crow's feet compared to the anti-aging cosmetic. While both treatments provided initial improvements, the RF device achieved statistically greater reductions in key roughness parameters (Ra, Rq, and Rz) throughout the 12-week study.
While cosmetics improve surface hydration, radiofrequency devices appear to drive structural change. The RF device reduced wrinkle roughness more effectively than topical treatments, likely by increasing skin thickness rather than relying solely on surface-level moisture.
Analyzing the Reduction in Crow's Feet
Superior Roughness Reduction
The primary measure of success in this comparison was the reduction of skin roughness. The side of the face treated with the RF device showed significantly better results than the cosmetic-treated side.
Consistency Over Time
The difference in performance was not a momentary spike. The RF device maintained a statistically significant advantage at multiple check-ins throughout the 12-week trial.
Performance Metrics
The study utilized specific technical parameters—average arithmetic roughness (Ra), average quadratic roughness (Rq), and roughness (Rz). Across these specific metrics, the RF device consistently outperformed the cosmetic application.
Structural Changes vs. Surface Improvements
Impact on Skin Thickness
The likely driver behind the RF device's superior wrinkle reduction is its effect on skin density. From week 4 through week 12, the RF device produced a significant increase in skin thickness.
Comparative Thickness Results
When directly compared, the cosmetic product could not match this structural change. The increase in thickness was significantly greater on the RF-treated side at weeks 4, 8, and 12.
Improvements in Radiance
Beyond wrinkles, the RF device also excelled in improving skin radiance. It showed a significantly greater increase in radiance at weeks 2, 4, and 8 compared to the cosmetic.
Understanding the Trade-offs
Hydration Parity
It is critical to note that the RF device was not superior regarding skin hydration. Both the cosmetic and the RF device significantly increased stratum corneum hydration, but there was no statistical difference between the two.
The Commitment Factor
The superior results of the RF device required a rigorous routine. The protocol involved 6-minute sessions, five days a week for the first two months, followed by three times a week in the third month.
Immediate vs. Sustained Effort
While cosmetics are often passive applications, the RF device required active use under supervision during the study. Achieving these results requires a willingness to adhere to a consistent, time-intensive protocol.
Making the Right Choice for Your Goal
Based on the distinct effects of each treatment, you should align your choice with your specific skin priorities.
- If your primary focus is deep wrinkle reduction: Prioritize the radiofrequency device, as it physically increases skin thickness and significantly reduces roughness metrics (Ra, Rq, Rz).
- If your primary focus is surface hydration: Stick with the anti-aging cosmetic, as it delivers identical hydration benefits to the device without the time commitment of a daily procedure.
- If your primary focus is overall radiance: Lean toward the radiofrequency device, which outperformed the cosmetic in brightening skin tone during the first two months.
For substantial correction of crow's feet, the evidence favors the structural benefits of radiofrequency over the surface-level effects of cosmetics.
Summary Table:
| Metric | Radiofrequency (RF) Device | Anti-Aging Cosmetic |
|---|---|---|
| Wrinkle Reduction (Ra, Rq, Rz) | Superior & Statistically Significant | Moderate / Surface-level |
| Skin Thickness | Significant Increase (Structural) | No Significant Change |
| Skin Radiance | High Improvement (Weeks 2-8) | Moderate Improvement |
| Hydration (Stratum Corneum) | Significant Increase | Significant Increase (Equal to RF) |
| Effort / Commitment | High (5 days/week) | Low (Passive Application) |
