Laser freckle can completely achieve the effect of freckle, because laser can act on deep skin tissue. It can completely remove stains, unlike traditional therapy, which only acts on the skin surface and cannot prevent the deep pigment from reappearing. As long as you go to a regular hospital for laser freckle removal and find an experienced doctor for freckle removal, it will not recur, but you should also take good care after treatment, especially sun protection, to avoid pigmentation on the skin.
