title: A five-patient prospective pilot study of a polycaprolactone based dermal filler for hand rejuvenation.
abstract: BACKGROUND
  Hand rejuvenation is becoming more popular as a complementary procedure to facial treatments. Current options include the relatively invasive lipofilling and the less invasive dermal fillers treatments, of which the latter often is too short lasting. An ideal product would therefore be minimally invasive, however, providing longer lasting results.
  
  
  OBJECTIVE
  The objective of this pilot study is to evaluate the safety and efficacy of a polycaprolactone based dermal filler for hand rejuvenation.
  
  
  METHODS
  The dorsum of the hands of five subjects was treated with 1.0 mL polycaprolactone based dermal filler per hand. Subjects were seen for follow-up visits after 1, 4, 16, and 24 weeks.
  
  
  RESULTS
  The results showed consistent and high patient satisfaction throughout the duration of the study using a Visual Analog Scale. Satisfaction was rated at 82% at 24 weeks and patients were 88% likely to return for repeat treatments on average. On the subject GAIS assessment, all subjects reported an improvement compared to pretreatment throughout the duration of the study. The physicians' GAIS results were very much improved (90%) and much improved (10%) compared to pretreatment throughout the 24 weeks follow-up.
  
  
  CONCLUSIONS
  The data of this small pilot suggest that the polycaprolactone based dermal filler is safe, well tolerated and effective for hand rejuvenation, and potentially offers a valuable addition to the current treatment armamentum. Additional studies in a larger patient population should be performed to confirm these findings.
