Plasma Pen skin tightening, also known as fibroblast therapy, is a non-invasive cosmetic procedure that uses plasma energy to stimulate collagen and elastin production. The treatment creates controlled micro-injuries on the skin’s surface, triggering the body’s natural healing process. This results in firmer, smoother skin, making it an effective solution for fine lines, wrinkles, sagging skin, and uneven texture. It’s particularly suitable for areas like the eyes, mouth, neck, and hands.
