The way you treat a cut can determine what kind of scar, if any that may develop. The way you care for that scar can determine too, how fast and to what extent it will fade.
Avoid getting cuts
Every time the skin gets cut, it scars. So protecting your skin with gloves, long pants, long sleeves whenever working around thorny, sharp, or jagged objects are necessary to avoid cuts.
Heal it properly
A wound that heals quickly and neatly is less likely to develop a scar. Therefore, clean all your cuts and scrapes properly and keep the would slightly moist with antibiotic ointment.
Do not pick at scabs
Picking scabs off a healing would could increase your chances of leaving behind a visible scar.
If you get cut and it is large enough, go to a doctor for stiches. But if it is small and you are concerned about scarring, use a butterfly bandage. Use it after the wound is thoroughly cleaned.
Well balanced diet
Protein and vitamin obtained by eating a good, well balanced diet help to heal right.
Treat scar with gentleness
Sweat glands, oil glands and hair glands are all destroyed by a scar. Scar due to a third degree burn should be lubricated with a good skin cream to protect them from abrasions.
Clean scars gently
One common source of abrasions to tender scars is a washcloth in the hands of an overzealous washer. So, wash gently.
Cover it with sunblock
Scars have less pigment. Cover all scars with a strong sunscreen whenever you head outside on a sunny day.
Do not be overly alarmed
Fresh scars are often noticeable but they will fade over time all by themselves.
