Plasma Pen converts nitrogen in the air into a fine plasma spark. Those tiny, controlled points tighten the surface of the skin and stimulate fresh collagen and elastin — a fibroblast treatment used for lax or sagging skin, not only around the eyes. It is well suited to loose skin on the face, neck and body, including post-pregnancy laxity, crepey texture and deeper wrinkles. The same precise energy can lift hooded or crepey eyelids and soften lines around the eyes, while also tightening areas such as the neck, abdomen and other places where firmness has been lost. Plasma Pen is also used for selected benign lesions: skin tags, moles that have been assessed as suitable, and keratoses (rough, crusty spots). Suspicious, changing or undiagnosed moles are not treated — those need a medical opinion first. Tiny carbon crusts form on the treated area and usually fall away in about 5–10 days. Tightening continues as new collagen builds over the following weeks.
