What causes a scar to form?
A
excess collagen
B
a bad cut
C
genetics
D
None of the above
Explanation: 

Detailed explanation-1: -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. In time, some collagen breaks down at the site of the wound and the blood supply reduces.

Detailed explanation-2: -Keloids are the result of excessive collagen production and can produce an ‘overhealing’ effect that results in excessive scar tissue. For most people, when they cut themselves shaving the wound will become slightly inflamed, scab over, and maybe leave a tiny scar.

Detailed explanation-3: -Luckily, there is a way to prevent excess production of collagen during wound healing. Enter silicone gel. Silicone gel has been used for over three decades in the management of scars due to its proven safety and efficacy.

Detailed explanation-4: -Although doctors remain unsure of what causes scar tissue to form, they do know that hypertrophic scars and keloids can result from burns, insect bites, acne, chicken pox, piercings, tattoos, and surgery. Researchers have also found that keloids develop more often in people with darker skin.
