The human skin metabolizes daily, produces waste and receives various attacks from UV rays, bacteria and dust, so it needs to be maintained regularly. Laser whitening is a medical aesthetic that uses new modern technology to achieve whitening effects on the human body. Since everyone reacts differently to laser treatment, the effect of whitening varies. Some people may be able to see the results right then and there after one session, while others may need some time after the laser treatment to see more visible results. Others may need a course of treatment, i.e. 3-5 times, to see more visible results. Usually a course of laser whitening can maintain the effect for about 1 year. Regular skin care is recommended after laser surgery to better maintain the treatment effect. After laser whitening, you must pay attention to sun protection, skin cleaning and daily skin care so that the whitening effect can be more lasting. In addition, laser whitening can also be performed together with other items, such as hydrophoresis, which can make the whitening effect more lasting.
