Evaluation of the efficacy and safety of plasma exeresis in periorbital rejuvenation using the Reviscometer®

Ablative radiofrequency microplasma for lateral dermatochalasis-indications and treatment recommendations

To determine in which cases ablative radiofrequency microplasma is preferred for the treatment of lateral dermatochalasis over a surgical approach as well as discussing each method's benefits and limitations. Twenty-one patients underwent 3 interventions of plasma exeresis. Photographic and RCM images were acquired at baseline and 4 weeks after final plasma exeresis. The eyes were categorized into 3 groups based on the dermatochalasis severity (1- mild, 2- moderate, 3- severe). Additionally, a further division was conducted to assess the degree of enhancement observed after the treatment (1- slight improvement, 2- moderate improvement, 3- significant improvement). The classifications and assessments were performed by was graded by two trained dermatologists as blinded observers. A total of 21 eyes with a mean age of 54 years (range45-67 years) and 100% females were included in this study. The severity of dermatochalasis directly affects the clinical improvement (P=0.039) and the higher the severity, the more the improvement (R = -0.62). Noninvasive ablative microplasma may offer safe and effective therapy for upper eyelid dermatochalasis and can even be performed in patients at surgical risk. However, it may be suitable for grades 0 and 1 of DC. For more advanced grades a surgical solution achieves better results for the treatment of dermatochalasis of the upper eyelid.

The quantitative investigation of spark plasma on skin parameters with skin elasticity, thickness, density, and biometric characteristics

Cold atmospheric plasma has been developed and utilized as a novel technique for skin rejuvenation because of its various effects on cells and living things. This study investigated the accuracy of this claim and any possible side effects of using spark plasma to rejuvenate skin. The present work is the first quantitative investigation using animal models. 12 Wistar rats were divided into two groups for this investigation. To compare the skin's natural process with the treated skin, the first group underwent a single session of plasma therapy, while the second group served as the control group. The back of the necks of the samples was shaved for 20 cm. Before beginning treatment, the MPA9 multifunctional skin tester was used to determine the melanin index, erythema index, and transepidermal water loss (TEWL). The skin's thickness and density were assessed using sonography, and its elasticity index was calculated using a Cutometer. The samples were exposed to plasma radiation in the designated area (in a triangular pattern). The abovementioned signs were examined immediately after the following therapy and at the weekly appointment 2-4 weeks later. Optical spectroscopy was also used to demonstrate the presence of active species. In this study, we found that a plasma spark therapy session significantly boosts skin elasticity, and the ultrasound results revealed a significantly increased skin thickness and density. The plasma increased the amount of skin surface evaporation, erythema, and melanin immediately following the treatment. However, 4 weeks later, it recovered to its former state and did not differ significantly from before the therapy.
