What you mainly need is time and massage, the normal healing period is around one year, after that time you will need a scar revision (most likely) and your surgeon should have tell you that.
In the mean time you can use any silicone base scar gel.
Be sure you see a board certified plastic surgeon (American Board of Plastic Surgery)
Hi. Looking at the scars you may need the scar revised later when it has faded - if you are happy waiting it is better to wait for a year or so to see what they look like. If you do not think you want surgery then you shold start having either a vascular laser or Fraxel laser treatments to reduce the redness and improve the texture of the scar. You will need at least 5 treatments looking at the scar. If the scar is tender then massaging the scar for a few minutes a day will improve the sensitivity and reduce the firmness of the scar. Best of luck with things. Dr Charles Cope
