Background And Objective: Carboxytherapy (CXT) is a minimally invasive procedure based on percutaneous or subcutaneous microinjections of carbon dioxide. Due to the Bohr effect, it influences the hemoglobin dissociation curve, improving tissue oxygenation, angiogenesis, facilitating vascular perfusion, and lymphatic drainage. Recent evidence suggests unconventional applications in dermatologic surgery and aesthetic medicine; these are focused with the present review.
Methods: A systematic review was conducted by searching the PubMed library from January 2018 to July 2023, using the terms "Dermatologic Surgery, Aging, Rejuvenation, Scars, Cellulite, Alopecia, AND Carboxy therapy." Eligibility criteria included original studies aimed at discussing CXT in dermatologic surgery and aesthetic medicine.
Results: The final synthesis included 41 articles distinguished by topic into studies on the role of CXT in facial rejuvenation (n.14), in cellulite, scars and fat deposits treatment (n.17), and other pathologic conditions (n.10). Overall, CXT is an effective antiaging treatment. Furthermore, CXT may play a role in several pathologic conditions including alopecia, lichen planopilaris, vitiligo, chronic diabetic wounds, temporomandibular arthralgia, and lipedema.
Conclusion: CXT, by promoting tissue oxygenation and microvascular and vascular perfusion, appears to have promising indications for several aesthetic and pathologic conditions, potentially offering satisfactory results with a minimally invasive, safe, and well-tolerated treatment.

"Mosaic graft" technique and surgical dermal glue in Mohs micrographic surgery and general dermatologic surgery.
Dermatol Reports
February 2025
Centro Dermatologico Vdermastudio, Viareggio.
After Mohs micrographic surgery, derm surgeons utilize local flaps, full or partial thickness grafts, with good or acceptable cosmetic results. When we are dealing with older and problematic patients, blood thinner users, and non-collaborative people with large facial neoplasms, using flaps may be very difficult, and grafts become the best choice. Our aim was to assess a technique to graft very easily, quickly, and safely, full-thickness skin grafts in facial wounds, and have good cosmetic results in those older and problematic people.

Russian Office of the APTOS LLC, Moscow, Russia.
Background: Facial thread lifting, which is popular in aesthetic medicine because of its minimal invasiveness, has led to advancements in the use of biodegradable polymers such as poly(L-lactide-co-ε-caprolactone) (P(LA/CL)) and its hyaluronic acid-coated variant (P(LA/CL)-HA). These developments enhance biocompatibility and efficacy, offering prolonged benefits through better biostimulation and tissue integration.
Methods: A controlled experiment involving five 4-month-old female pigs compared the effectiveness of P(LA/CL) and P(LA/CL)-HA threads over six months.

Department of Burn and Plastic Surgery, Govt. Kilpauk Medical College, Chennai, Tamil Nadu, India.
Background: Burn wounds are commonly encountered in clinical settings and the management aims at the prevention of mortality and morbidity due to disability. The platelet-rich plasma (PRP) is blood-derived biomaterial that is enriched with growth factors and cytokines that facilitate wound healing. The PRP has proven its efficacy in various other wounds, but its role in post-burn raw areas and graft take has not been validated.

Methods: In total, 154 patients with severe burns who underwent Meek micrografting treatment were selected as the observation group, and 80 healthy people were taken as the control group. General clinical data were collected, and serum T-AOC, SOD, and MDA were analyzed by biochemical analysis.
Defining Predictive Factors for Permanent Chemotherapy-Induced Alopecia: Trichoscopy, Reflectance Confocal Microscopy and Histopathology Study on 77 Patients.
Dermatol Ther (Heidelb)
March 2025
Dermatology Unit, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.
Introduction: Literature about trichoscopy of permanent chemotherapy-induced alopecia (pCIA) is still scarce, while no data were published regarding reflectance confocal microscopy (RCM). The aim of our study is to monitor the different phases of chemotherapy-induced alopecia development with trichoscopy and RCM, in order to identify predictor factors for permanent alopecia.
Methods: This multicentre, prospective, observational study evaluated patients with cancer who were candidates for chemotherapy with a drug implicated in pCIA development.
