After complete recovery from acne, most people will form scars or some hypertrophic scar keloids. Generally, during the recovery phase of this condition, scratching or squeezing by hand is somewhat related. Currently, there are no highly effective drugs to completely heal these scars. The most common method is still to visit the dermatology department of a formal hospital and use fractional laser treatment, but the results vary from person to person and require many treatments. If the results are poor and the scar keloids are significantly hypertrophic, drug occlusion can also be used. However, drug occlusion cannot completely eliminate them; it can only make them shrink or become less noticeable. There is still a possibility that they might continue to grow.
