The advantages of laser age spot removal are fast and effective; the disadvantages are that it will cause short-term adverse skin reactions and may lead to the occurrence of scars, hyperpigmentation, thermal burns and other adverse reactions. 1. Advantages: laser age spot removal uses laser to penetrate the damaged skin and selectively act on the abnormal pigment particles, which will change under the powerful laser irradiation and then dissipate by itself, so that the age spots can be reduced or disappeared. This way can get rid of age spots quickly and effectively, and the treatment effect can be maintained for about 1~2 years. 2. Disadvantages: After laser treatment, the local skin will have transient adverse reactions such as redness, swelling, pain and pigmentation, which are normal skin reactions and require certain repair time; improper operation of laser treatment may lead to skin burns, burns, erythema, blisters and other symptoms; improper operation may also lead to deep burns, which may result in the appearance of depressed scars or hyperplastic scars. It is recommended that people who need to get rid of age spots should go to regular hospitals and choose the best treatment plan under the guidance of doctors in order to avoid the occurrence of adverse reactions and achieve satisfactory treatment results.
