It works on principle of Bio-Stimulation. Basically, the Softlaser laser light stimulates the Mitochondria (the cell's powerhouse) in the cells to produce ATP. Increased ATP energizes the cell, making it reproduce faster which in turn, leads to more collagen production. The Softlaser light also promotes cell wall exchange, leading to increased blood circulation. Both effects lead to tighter, healthier skin and reduced healing times for conditions like acne or small cuts and insect bites.
