A lot of scars on legs may be relieved by medication such as heparin sodium cream, laser treatment and microdermabrasion. 1. Medication: During the period of scar proliferation, medications such as sodium heparin cream and mucopolysaccharide polysulfate cream can be used under doctor’s guidance to improve the appearance of the scar by inhibiting scar proliferation. 2. Laser treatment: The high temperature generated by laser can cause thermal damage to the local area and promote collagen regeneration and rearrangement to improve the appearance of keloid scars. 3. Microdermabrasion: Microdermabrasion is a procedure that can remove scar tissue such as hyperplasia and restore the local skin to a flat state to improve the appearance of the scar. If you have a lot of scars on your legs, it is recommended that you go to a regular hospital for appropriate treatment and avoid blindly treating the scars on your own, so as not to cause adverse consequences.
