Hi, I Met With A Road Traffic Accident 10 Years

Hi,
I met with a road traffic accident 10 years ago, and it resulted in friction burns over the right half of my face and nose.
Although the scars have improved throughout the years, it is still visible.
Could you please suggest home remedies,or creams/ointments I could use to improve the appearance of my scars?
Would taking omega 3 oils and vitamin e orally help?
Thanks
