WebThe treatment works by delivering radiofrequency energy to the deeper layers of the skin through tiny pins, which stimulates collagen production and tightens the skin. Morpheus8 can also treat acne scars and stretch marks. It has become increasingly popular among those seeking a minimally invasive, natural-looking solution to skin aging. WebLaser Diodes vs. Helium Neon Lasers. A very common laser question is, "When is a HeNe more suitable than a diode or vice-versa?" The answer to this question is application dependent. The easiest way to make an informed decision is to understand the advantages and disadvantages of each type of laser, based on your needs.
