Unfortunatly,no scar can ever be completely erased; and no magic technique will return the scar to its normal uninjured appearance.
Scars result when the skin repairs wounds caused by accident, disease, or surgery. They are a natural part of the healing process. The more the skin is damaged and the longer it takes to heal, the greater the chance of a noticeable scar.
Typically, a scar may appear redder and thicker at first, then gradually fade. Many actively healing scars that seem unsightly at three months may heal nicely if given more time.
here are some tips/techniques. Hope 1 or more helps
Pressure bandages and massages can flatten some scars if used on a regular basis for several months.
Silicone-containing gels, creams, and bandages have also been helpful in reducing scar thickness and pain. They must also be used regularly and results are variable.
Cryosurgery involves freezing the upper skin layers which causes blistering of the skin. This can sometimes cause scars to diminish in size. This technique has been used on raised acne scars.
Cortisone (steroid) injections or tapes are effective in softening very firm scars (or keloids) causing them to shrink and flatten. This is usually the treatment of choice for hypertrophic scars and keloids.
Silicone impregnated gels can be used by the patient at home to remodel elevated scars in addition to injections of scar tissue.
Interferon is a chemical that can be given by injection and may help improve the hardness and cosmetic appearance of the scar.
Cosmetics applied correctly can be very good at covering up scars. Physicians encourage patients to wear make-up after scar treatments. Make-up will improve the appearance while nature completes the healing process. Well, this one is more suited for acne scars or scares that are more visible. (neck, face arm...)
PS I have 5 small X like scars in my abdomen from surgery about 6-7 years ago. They are slowly fading. Most of my scars from burns or surgery have almost completly faded to where they are hardly noticable. Perhaps yours will eventually fade too, given time
Will it fade in time? What can I use to help it along?
