Calf scar marks are mainly caused by pigmentation, which can be removed by medication and laser treatment. 1. Drug treatment: under the guidance of the doctor, you can use Mucopolysaccharide polysulfate cream, cumeneoside cream ointment, hydroquinone cream and other medications, which have the effect of promoting the absorption and metabolism of melanin and lightening pigmentation. 2. Laser treatment: you can choose the way of fractional laser, mainly using fractional laser to produce an array of beams to improve the phenomenon of pigmentation. Picosecond laser, photorejuvenation and other strong pulse laser can also achieve similar results, but generally need multiple treatments. The removal of calf scar marks needs to be carried out in a regular hospital to avoid improper operation, which may stimulate local scar proliferation or aggravate pigmentation.
