Plasma needling is a minimally invasive aesthetic medical procedure purported to rejuvenate skin, minimize the appearance of hypertrophic and hypotrophic scars and stretchmarks, and reduce pattern hair loss through multimodal physical and biochemical cellular stimulation.
Plasma, often called the fourth state of matter, is an ionized gas containing positive ions and negative ions or electrons, but is approximately charge neutral on the whole. The plasma sources used for plasma medicine are generally low temperature plasmas, and they generate ions, chemically reactive atoms and molecules, and UV-photons.
Platelet-rich plasma therapy is a minimally invasive procedure that may be used in aesthetic medicine to treat skin conditions such as the removal of wrinkles, the reduction of lines, and improvement of blemishes, and hair loss. Concentrated PRP solution is injected into the treatment area to target damaged cells and tissues.
Some studies have also shown that when combined with minoxidil treatment, microneedling is able to treat hair loss more effectively than minoxidil treatment alone. [2] Platelet-rich plasma (PRP) can be combined with collagen induction therapy treatment in a form of dermatologic autologous blood therapy.
The plasma pencil is a dielectric tube where two disk-shaped electrodes of about the same diameter as the tube are inserted, and are separated by a small gap. Each of the two electrodes is made of a thin copper ring attached to the surface of a centrally perforated dielectric disk.
If the voltage is sufficiently high (> 400 V peak-to-peak) [11] the vapor sheath is ionized, forming conductive plasma. Electric current continues to flow from the metal electrode through the ionized gas into the tissue. Rapid overheating of tissue results in its vaporization, fragmentation and ejection of fragments, allowing for tissue cutting ...
