The overall effect of laser spot removal is very good, but it needs to be divided into specific types, as follows: 1.Freckles: freckles can be treated in many ways, and the effect is better, but it is very easy to recur, and it is related to the depth, severity, sun exposure time and intensity of freckles. If no attention is paid to sun protection after freckle treatment, it may recur quickly, and if it is better protected, it may last longer; 2. Sun spots: due to the popularization of sun protection knowledge, sun spots are relatively less and shallow, and the effect of laser treatment is very good; 3. Melasma: because of its very complicated causes, the effect of laser treatment is not very certain, it may be effective or average, and more attempts are needed. In addition, melasma is irritable in nature, when treating melasma, low energy and high frequency treatment plan is generally adopted to avoid melasma from becoming more serious. Therefore, the effect of laser spot removal varies, depending on individual body type, the type of spot and the treatment plan. In addition, good care and maintenance help to ensure the effect of spot removal.
