The Clinical Efficacy of ReCell Autologous Cell RegenerationTechniques Combined with Dermabrasion Treatment in AcneScarsAbstractObjective To evaluate the efficacy of ReCell autologouscell regeneration techniques combined with dermabrasiontreatment on the therapy of acne scars.Methods We analyzed retrospectively 78 patients withacne scars who presented to the Department of PlasticSurgery at Peking Union Medical College Hospital fromMay 2015 to May 2017; 30 patients were treated withdermabrasion (Group 1), and the other 48 patients weretreated with ReCell autologous regeneration techniquescombined with dermabrasion (Group 2). Efficacy wasevaluated through self-evaluation of the patient, third-partyevaluation and photographs taken before and after treatment.The wound healing time and postoperative complicationrate were also recorded.Results The study revealed a significant difference inhealing time (P\0.001) between patients treated withdermabrasion (Group 1) and patients treated with ReCellautologous regeneration techniques combined with dermabrasion(Group 2). The average healing time of Group 1was 12.30 ± 1.725 days, while the average healing time ofGroup 2 was 5.27 ± 1.086 days. In Group 2, patient selfevaluationand third-party evaluation were more satisfactorythan those of Group 1 (P\0.001). Moreover, therewere no postoperative complications in Group 2 such aspigmentation and scar hyperplasia.Conclusion The ReCell technique is simple, minimallyinvasive, biocompatible and effective in the treatment ofacne scars. It can shorten healing time and reduce theoccurrence of postoperative complications, thereby providinga safe and effective treatment approach for patientswith facial acne scars.Level of Evidence IV This journal requires that authorsassign a level of evidence to each article.

AbstractBackground: Regenerative Epithelial Suspension can lead to the restoration of woundand repigmentation, which can be gained by ReCell medical device to treat scar anddepigmentation diseases.Objectives: To report the effectivity of ReCell combined with microdermabrasion inscar and depigmentation diseases and review the literature of this new technology.Methods: We gave a differential donorrecipient ratio of about 1:20‐30 with vitiligo,1:40 with postburn construction, 1:80 with acne scar, and 1:120 with adult congenitalmelanocytic nevus, 1:80 with pediatrics, respectively. Photographs of patientsbefore treatment and 3 months following the last treatment session were used toevaluate the effectivity.Results: A total of 8 patients including vitiligo vulgaris, postburn reconstruction, acnescars, and congenital melanocytic nevi treated by ReCell technology combined with microdermabrasionshowed significant improvement in skin texture and color. And 17 studiesof the research on ReCell technology were totally included in the systematic review.Conclusion: Our investigation showed that Regenerative Epithelial Suspensiongained by ReCell technology combined with microdermabrasion may improve scarand depigmentation diseases.K E Y W O R D Sacne, burn, noncultured autologous cell, scar, vitiligo
