Expression of HSP70 in Human Skin After Cryolipolysis Treatment
BACKGROUND: Cryolipolysis nonsurgically targets and reduces subcutaneous fat through controlled cooling of skin and underlying fatty tissue. Although skin changes after cryolipolysis treatment have been observed clinically, the mechanisms by which these occur are not well understood. OBJECTIVES: The...

description | BACKGROUND: Cryolipolysis nonsurgically targets and reduces subcutaneous fat through controlled cooling of skin and underlying fatty tissue. Although skin changes after cryolipolysis treatment have been observed clinically, the mechanisms by which these occur are not well understood. OBJECTIVES: The aim of this study was to investigate the expression of heat shock protein 70 (HSP70) in the epidermal and dermal layers of human skin following cryolipolysis treatment. METHODS: Subjects (N = 11; average age, 41.8 years; average BMI, 29.59 kg/m(2)) were recruited to receive cryolipolysis treatment with a vacuum cooling cup applicator (−11°C/35 minutes) prior to abdominoplasty surgery. Treated and untreated abdominal tissue samples were harvested immediately after surgery (average follow-up, 15 days; range, 3 days to 5 weeks). Immunohistochemistry for HSP70 was performed on all samples. Slides were digitized and quantified in epidermal and dermal layers. RESULTS: There was higher epidermal and dermal HSP70 expression in cryolipolysis-treated pre-abdominoplasty samples vs untreated samples. There was a 1.32-fold increase of HSP70 expression in the epidermis (P < .05) and a 1.92-fold increase in the dermis (P < .04) compared with untreated samples. CONCLUSIONS: We found significant induction of HSP70 after cryolipolysis treatment in epidermal and dermal layers. HSP70 has potential therapeutic benefits and is recognized to have a role in skin protection and adaption after thermal stress. Although cryolipolysis is popular for subcutaneous fat reduction, cryolipolytic HSP induction in the skin may prove valuable for additional therapeutic applications, including skin wound healing, remodeling, rejuvenation, and photoprotection.
