Improve not remove. It is not possible to remove a scar once it has formed but it may be possible to improve them. Avoid sun exposure with the use of a high spf sunblock as well avoiding tobacco use. The wound should be kept clean and moist until healed followed by possible use of silicone gel sheeting or ointment for 4-9 months.
