Background: The Clinician Reported Photonumeric Cellulite Severity Scale (CR-PCSS) and Patient Reported PCSS (PR-PCSS) are newly developed tools for assessing cellulite severity.
Objective: To report on the reliability, validity, and ability to detect a change in cellulite severity on the buttocks of adult women with the CR-PCSS and PR-PCSS.
Materials And Methods: Content validity of both scales was established through concept elicitation and cognitive interviews. Test-retest reliability was evaluated, and intra-rater (both scales) and inter-rater (CR-PCSS only) reliability were estimated using intraclass correlation coefficients (ICCs) for agreement and consistency. Ability to detect a change was determined using the Subject-Global Aesthetic Improvement Scale (GAIS) or Investigator-GAIS as anchors.
Results: For the CR-PCSS (n = 6) at baseline and Day 2, the mean interrater ICCs were ≥0.70 and mean intrarater ICCs (95% confidence interval [CI]) were ≥0.81 (0.72-0.90) for both buttocks. For the PR-PCSS (n = 99) at baseline and Day 14, the mean test-retest reliability ICCs (95% CI) were ≥0.86 (0.79-0.91) for both buttocks. A clinically meaningful change was 1.0 point on the PR-PCSS and 1.0 on the CR-PCSS.
Conclusion: The CR-PCSS and PR-PCSS reliably assess cellulite severity of the buttocks and can detect a clinically meaningful change after treatment for cellulite.

A Retrospective Pragmatic Longitudinal Case-Series Clinical Study to Evaluate the Clinical Outcome of Triple-Frequency Ultrasound in Treatment of Cellulite.
Clin Cosmet Investig Dermatol
December 2024
Wellcomet GmbH, Bruchsal, Germany.
Objective: In this single-centre, retrospective, pragmatic, longitudinal case-series clinical study triple-frequency LDM (TF-LDM) technology with frequencies of 1/3/10 MHz and 3/10/19 MHz was applied for treatment of cellulite to reveal the effect of these waves on the cellulite skin and assess the sustainability of treatment outcomes during the long-term follow-up controls.
Methods: Twenty Caucasian females with mild-to-severe gynoid lipodystrophy aged 27-53 years who received cellulite monotherapy with TF-LDM were included in this study. All participants were evaluated at three time points: baseline (T1), on the day of the last treatment (T2), and during the last follow-up (T3).

This case report presents a 67-year-old male with a history of metabolic syndrome, uncontrolled diabetes mellitus, hypertension, and prostate cancer, who underwent radio electric asymmetric conveyer (REAC) biomodulation treatments, specifically anti-cellulite treatment (ACT), circulatory optimization (CO), and metabolic optimization (MO). The patient initially presented with severe pain and edema in the left lower limb, requiring morphine. Over three months, he received a combination of ACT, CO, and MO protocols.

Background: Ultrasound energy can successfully treat fine lines and wrinkles, as well as lift the eyebrow and submentum. Ultrasound waves of high intensity induce thermal injury in the dermis with subsequent tissue remodeling.
Objective: To examine the utility of a novel ultrasound device that utilizes high-intensity, high-frequency, parallel ultrasound beams to improve the clinical appearance of cellulite on the thighs and buttocks.
