Infrared thermography as valuable tool for gynoid lipodystrophy (cellulite) diagnosis

Area of Science:

• Dermatology
• Medical Imaging
• Aesthetics

Background:

• Cellulite is a common cosmetic concern affecting skin morphology and self-esteem.
• Its exact etiology and pathophysiology remain unclear, with visual assessment not fully reflecting subcutaneous tissue conditions.
• Current diagnostic methods lack objective measures for cellulite severity.

Purpose of the Study:

• To investigate the correlation between tissue heterogeneity measured by infrared thermography and cellulite severity.
• To establish infrared thermography as a reliable, objective tool for cellulite assessment.
• To guide treatment selection based on objective cellulite characteristics.

Main Methods:

• Forty female participants were enrolled, with 60 thighs analyzed.
• Clinical history (anamnesis) and infrared thermography were employed for assessment.
• Spearman's rank correlation coefficient was used to analyze data.

Main Results:

• A strong positive correlation (R=0.92) was found between visual cellulite evaluation and tissue heterogeneity measured by thermography.
• Phototype showed a significant negative correlation (R=-0.67) with visual cellulite assessment.
• Infrared thermography provided an objective measure of cellulite severity, correlating highly with clinical judgment.

Conclusions:

• Infrared thermography is a simple, effective method for objectively grading cellulite severity in aesthetic practices.
• This method correlates well with traditional visual assessments (R=0.92).
• Thermography can assist clinicians in choosing between pro-inflammatory (e.g., radiofrequency, shockwave) or anti-inflammatory (e.g., photobiomodulation) treatments based on cellulite's inflammatory status.
