Abstract

Objectives: The face aging processes are associated with physiologic and biochemical alteration that produces wrinkles, skin pigmentation and benign growths. The aim of this study was to evaluate the clinical efficacy of voltaic arc dermabrasion with plasma to remove benign facial skin lesions.

Study design: Voltaic arc dermabrasion plasma technique was used to remove the facial benign skin lesions. The study involved 45 patients (26 females;19 males) treated for benign facial skin lesions with voltaic arc dermabrasion also called plasma exeresis technique. The subjects age ranged between 43 and 65 years. The clinical observations and comparison of pretreatment and post-treatment photographs of the treated regions were performed by a joint examiner at each follow-up visit.

Results: During plasma irradiation, the average temperature of the skin was 290.3 ± 21.7 °C, while immediately after it was 90.6 ± 21.8 °C. Overall clinical improvement was 100% in six lesions with complete resolution of all lesions. Three patients observed a transient post-inflammatory pigmentation with a peak at 1 month after VAD treatment, gradually fading spontaneously over 2 to 3 months.

Conclusions: The voltaic arc dermabrasion technique (atmospheric plasma) should be considered for lesions, especially relatively superficial ones, and small lesions that are located on the face.

The pin does not work if held in direct contact with the tissue to be treated, since it requires a small gap to be left for the generation of the plasma forming electric arc. VAD produces a carbonaceous residue layer formed after plasma exeresis
