8. Keep the wound moist
If you keep your wound moist, and it will heal more quickly and the scar will be less noticeable.
A dry wound will scab. The scab protects against external factors, such as bacteria. However, the cells under the scab will heal less quickly. The more quickly the wound heals, the lesser the scar.
So, provide a physical layer to keep bacteria out, and keep the skin underneath moist. Topical antibiotics such as Neosporin are good initially, but can cause skin irritation when used for a long period of time.
A better choice for long-term use is a petroleum jelly such as Vaseline. These will keep bacteria out and prevent evaporation of moisture from the skin, keeping the skin moist and aiding healing.
