Effects of Cryolipolysis on the Conversion of White Adipose Tissue: Pilot Study.

ABSTRACT

INTRODUCTION: Cryolipolysis (CLL) is a widely employed noninvasive procedure for body fat reduction. It operates by inducing cooling, leading to the crystallization of cytoplasmic lipids, loss of cellular integrity, and apoptosis/necrosis of adipocytes, accompanied by local inflammation. Ongoing discussions revolve around CLL's potential to transform white adipocytes into brown adipocytes, potentially yielding more significant effects compared to alternative procedures. OBJECTIVE: Thus, this randomized, blinded clinical study aimed to investigate the effects of CLL on adipose tissue and elucidate the mechanisms involved in its application and capacity for adipocyte conversion. METHODOLOGY: Tissue samples from six patients were assessed at intervals of 45, 60, and 90 days following the application of the CLL protocol during abdominoplasty surgeries. RESULTS: The samples underwent immunohistochemical analyses targeting various markers, revealing higher expression of PPAR-gamma, PPAR-alpha, and UCP-1 markers in CLL-treated samples. CONCLUSION: Therefore, the present study suggests that CLL has the ability to intervene in adipocyte conversion.
