When the dermis is stretched or torn, it can result in the appearance of visible, silvery-white scars on the skin. This is due to the production and deposition of collagen fibers in the affected area, which can be different from the surrounding skin. Tactile corpuscles do not play a role in this process, blood vessels rupturing and causing bruises are a different phenomenon, and tension lines disappearing is not a specific indicator of dermal tearing.
