Histological studies of facial acne and atrophic acne scars treated with a bipolar fractional radiofrequency system

PubMed Reference:Kaminaka C, et al. J Dermatol. 2014 May;41(5):435-8.

Study Details: 

  • 6 subjects with atrophic acne scars and acne vulgaris
  • Histological studies to compare one vs. two passes with fractional RF

Study Results:

  • 2-pass treatment created deeper dermal thermal injury zones compared to 1-pass treatment
  • Collagen was coagulated in the sebaceous glands and periadnexal structures after 2-pass treatment
  • No severe side-effects were observed after treatment 
  • Large benefit is the preservation of adnexal structures.
