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.
