  • How do scars form?

  • It is a secret process.

  • I can't reveal it.

  • No.

  • It's not a secret process.

  • A scar is formed when our skin tissue heals itself after an injury.

  • Our skin tissue has collagen.

  • Collagen is a structural protein produced by fibroblasts.

  • Collagen keeps our skin firm and it is usually arranged in a 'basket weave' pattern.

  • Can I use this basket to keep my bags of chips?

  • Please listen.

  • When we get injured, our skin tissue gets damaged.

  • So, in order to heal and close the wound, fibroblasts produce more collagen.

  • But, instead of arranging in a basket weave pattern, the collagen cross-links and aligns in a single direction.

  • As a result, the injured area of the skin appears different from normal skin, thus causing a scar.

  • Hold on guys.

  • Can you guess the title of my next video?

  • Hurry up.
