The plasma pen is used for eliminating wrinkles and tightening the skin. It works by releasing a small electrical charge with plasma gas using a small needle like probe. This stimulates the fibroblast cells to react to the superficial trauma and immediately starts to tighten the skin. The results are visible immediately but maximum results will be visible 3 to 4 weeks after treatment. 2 sessions may be needed and the effects can last up to 3 years depending on lifestyle.
