How scars are formed?
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 raised and lumpy.
How to minimise scars?
To be effective, silicone gels or sheets should be placed over the scar for 12 hours a day for at least 3 months. They can be washed and reused.
