Have you ever wondered how scars are formed?

A scar is a mark left on the skin after a wound or injury has healed. ₁

Scars are a natural part of the body’s healing process. A scar results from the biologic process of wound repair in the skin and other tissues. Most wounds, except for very minor ones, result in some degree of scarring.

Scars can result from accidents, burns, diseases, skin conditions such as acne, or surgeries. ₂

When the skin is wounded, the tissues break, which causes a protein called collagen to be released. Collagen builds up where the tissue is damaged, helping to heal and strengthen the wound.

New collagen continues forming for several months and the blood supply increases, causing the scar to become red, raised and lumpy.

In time, some collagen breaks down at the site of the wound and the blood supply reduces. The scar gradually becomes smoother, softer and paler. ₃

Silicone gel, such as Nourisil MD, can be used on healing skin (not open wounds) to help soften and flatten a scar. They can also relieve itching and discomfort.

To be effective, silicone gel should be placed over the scar for 12 hours a day for at least three months.₄
