Scars

• Many cuts isolated to the epidermis won't scar but if a cut makes it to the dermis, it will often scar.
• Scars won't look like the rest of the skin because when fibroblasts are generating collagen they tend to not arrange it in the same pattern that was originally there before.
• Things like sweat glands or hair will also not be recreated there
• Scar tissue tends to have less elasticity, and if its a big scar this can affect movement
• A keloid is when too much collagen is produced and the fibroblasts keep trying to fix a scar even when it's already been fixed.
