The principle of handheld nanosecond lasers is to use a technology called "Q-switch". It controls the tunable lens inside the laser to emit the laser at a nanosecond speed. This high-speed pulse laser can effectively improve skin problems such as pigmentation, acne, and skin laxity.
The main function of handheld nanosecond lasers is to destroy pigment particles or acne bacteria on the skin surface, as well as stimulate the regeneration of collagen. For pigment deposition, nanosecond laser can cause pigment particles to rupture and decompose, and be excreted from the body through the lymphatic system. For acne, nanosecond laser can kill bacteria and reduce inflammation. In addition, nanosecond laser can also promote collagen regeneration, enhance skin elasticity and firmness.
Compared to traditional beauty devices, handheld nanosecond lasers have multiple advantages. Firstly, it is handheld and highly portable, allowing for skin treatment anytime, anywhere. Secondly, the effect of nanosecond laser is more precise, only destroying pigment particles or acne bacteria, and will not cause damage to surrounding normal skin. In addition, the recovery time of using nanosecond laser for treatment is shorter, and patients can quickly return to normal life.
