title: Photodynamic Photorejuvenation: A Review.
abstract: BACKGROUND
  Topical photodynamic therapy (PDT) is acknowledged to be a safe and efficient therapeutic option for the selective destruction of actinic keratosis and superficial carcinomas. Over the past 15 years, topical PDT has also been shown to be a possible method for "photorejuvenation."
  
  
  METHODS
  An extensive review was performed of in vitro and in vivo (animals, organ transplant recipients, or immunocompetent patients) studies.
  
  
  RESULTS
  The studies point to a high level of efficacy. Tone, lentigos, skin roughness, and moreover texture and fine wrinkles because of the effects of dermal remodeling are improved. Adverse effects are generally described as mild to moderate, without scarring, along with a fast recovery time. Patients with fair phototypes and a history of sun exposure and actinic damage of varying severity are the best candidates for this technique. Photodynamic photorejuvenation sessions can both rejuvenate their skins and also treat their visible or incipient UV-induced lesions. New protocols either with daylight use and/or previous intensification by laser or microneedling seem promising.
  
  
  CONCLUSIONS
  The photodynamic rejuvenation technique seems to show excellent short-term efficacy and tolerability.
