The honeycomb picosecond laser is based on the picosecond laser energy with the addition of a honeycomb lens, which refocuses each laser beam for hundreds of times amplification, generating hundreds of laser dots to form more cavities in the deeper layers of the skin, breaking down pigment cells, sagging aging cells and broken elastic fibers, causing the body to initiate a regenerative repair mechanism and new large amounts of collagen and elastic fibers, thus restoring the skin to firmness and elasticity. This method has a wide range of application, and can also achieve scarless spot removal with less risk of rebound. However, if rebound occurs, it is usually related to poor post-operative care. In order to effectively avoid this situation, beauty seekers need to take the following measures: 1.Strengthen sun protection: Because ultraviolet rays will cause skin discoloration and aging, the area after spot treatment is more sensitive to sunlight, if you do not pay attention to sun protection, it is more likely to lead to rebound; 2.Pay attention to moisturizing: Picosecond laser will make the treatment area produce thermal effect, therefore, many beauty seekers will feel their skin is dry after doing honeycomb picosecond. 3. Avoid intense exercise: after the honeycomb picosecond spot removal, avoid doing strenuous exercise, especially the action that is easy to sweat, and carry out appropriate stretching exercise.
