Postsurgical soft-tissue injuries, as a result of common cutaneous surgical procedures such as biopsies or excisions, can result in permanent normal or complicated scars, with unpleasant esthetic appearance. To improve the scar appearance, many pharmacologic measures are performed, such as silicone gel, 5-fluorouracil or corticosteroids injections, with good clinical results.[1] For unresponsive scar or as alternative therapy, laser treatment may be very effective.[1] Ablative laser treatment, in particular, carbon dioxide and erbium lasers, has been used for the treatment of scar, often with significant collateral effect arising during the reepithelization process.[2] In contrast, nonablative laser treatment using infrared wavelengths, such as 1320-nm Nd:YAG or 1450-nm diode, creating a controlled dermal wound without epidermal disruption results in more safe treatment of the scar.[2],[3] Posttreatment collateral effect can also occur in patients receiving fractional laser therapy.[2],[3]

The demand for noninvasive and safe technology for the treatment of scar paved the way for the research of novel therapy with less collateral effect and more efficacy. Plasma skin regeneration (PSR) is a new technique consisting of generation of plasma energy through the production of ionized energy that thermally heats tissue, through a plasma radiofrequency (P-RF) device.[4],[5]

A 45-year-old woman with a 5-month history of normal scar of the upper lip, with focal hypertrophy at the peaks caused by the emerging sutures, following surgical excision of a skin cancer [Figure 1]a was treated with P-RF device (D. A. S. Medical, Technolux, Italia), a tool that work with long-wave P-RF principle. Before starting treatment, she signed an informed consent form. No contraindications to treatment, such as Fitzpatrick skin Types V-VI, concomitant bacterial or viral infection, collagen vascular disorders, diabetes, malignancy, pregnancy, and ablative skin procedures carried out within the previous 3 months, were present. After careful disinfection of the skin with antiseptic solution, long-wave plasma- RF (LWP-RF) ablation was performed without anesthesia. The margins of the scar were superficially ablated with one pass at 0.6 J energy and 3 Hz frequency, delivered in a paintbrush fashion, with detached spots of sublimation, leaving columns of intact epidermis, and without touching the central linear fibrous part of the scar. Focal hypertrophy at the peaks of the scar was fully ablated with two passes of the same values of energy and frequency, with no columns of sparing tissue. Treatment consisted of two sessions, carried out at 30-day interval. After LWP-RF procedure, she applied an antibiotic ointment for a few days, avoiding sun exposure during the sessions and for 5 months after the last session. The treatment was well tolerated, and no adverse effects were observed. The patient was followed up at 3 and at 6 months from the last treatment. Significant clinical improvement of the scar was already observed after only a single LWP-RF session [Figure 1]b.

P-RF device utilizes plasma energy created from the ionization of atmospheric gas between the device and the skin. Contrary to ablative treatments (lasers or traditional radiofrequency), plasma sublimation leaves a layer of intact and desiccated epidermis that acts as a natural biologic dressing and promotes a more rapid recovery, avoiding to damage the deeper layers of the skin and predisposing to better healing with best esthetic results. Treatment can be made without anesthesia because of its quickness, and low and tolerable pain stimulation. In conclusion, PSR with a low-energy setting, combined with the absence of anesthesia, quickness and low cost, could represent an effective option for the treatment of scars. Further studies with larger samples are needed to determine the efficacy of this technique in the treatment of scars.
