Complan is still effective in removing scars. The main ingredient of Conrabo is sodium heparin allantoin, so it is an effective drug for scar removal, especially for some scar tissue that has just formed in the early stage, or scar hyperplasia tissue. The topical application of Conradipine is applied topically, and after the topical application, it is gently massaged. Generally, it is used 3-4 times a day and needs to be used continuously for a period of time, ranging from 1 month to several months depending on the state of the skin lesions. If the acne is just formed by acne marks or scars, generally use for 20 days to 1 month. If the scars are formed by other traumas, it depends on the length of time the scars have been formed, and if they are longer, the duration of the medication is relatively longer.
