Hello! I will assist you today. Scar tissue cannot be removed without surgery but it can be reduced using various creams/lotions to help lubricate the area and make it softer. This will result in a significant reduction in the scar hardness, etc but takes several months and will not totally eliminate the scar.
What if internal
With an internal scar it is impossible to reduce or remove the scar tissue without surgery. There are some laser surgeries that may be effective depending on exactly where the scar is but an internal scar cannot be reduced through medication, etc.
