Cryotherapy and laser treatment have their advantages and disadvantages, and both are treatment methods for swellings and spots on the human body surface. The choice of the specific treatment plan for the patient is individual, and should be made under the judgment of a professional doctor according to the condition of the lesion, the recovery period, and whether or not the patient is under anesthesia. Therefore, the comparison of the effect of cryotherapy and laser treatment cannot be generalized and should be analyzed for different situations: 1. At the same time, because the operation is simple and fast, no anesthesia is needed, so if the patient is a child, it is also recommended to choose. Usually, after a treatment, patients can recover in about 1 week; 2. Disadvantages: The treatment depth of this modality is shallow, so some patients need several treatments to heal. In addition, cryotherapy is more damaging and more likely to leave significant discoloration, with the possibility of scar formation, depending on the situation, there is variability in the retention of trauma. The actual laser treatment: 1. Advantages: If the patient has a small basal rash with a tip, it is recommended to choose laser treatment. The depth of laser treatment is deeper, and most patients can be cured with one treatment. Another advantage of laser treatment is that the possibility of leaving trauma is small, i.e. less damage, so laser treatment is usually chosen to remove spots; 2. Disadvantages: However, after treatment, the recovery of the trauma is slow, and if the patient’s postoperative trauma is large, it also needs to be paired with medication to assist recovery, and it usually takes about 1 month to fully recover. Laser treatment requires local anesthesia for the patient, and the pain is more obvious during the treatment. In summary, cryotherapy and laser treatment have their own unique advantages for different situations, and patients should follow medical advice to choose according to their own situation.
