What causes a scar?
Our bodies have an amazing ability to repair injuries. If a skin wound stays superficial and doesn’t penetrate completely through the layers of the skin, then the skin is able to repair itself without leaving a visible scar. This kind of wound is similar to a scraped knee, or an intentional wrinkle-reducing laser burn. A visible scar forms when an injury breaks the integrity of all the layers of the skin to the underlying subcutaneous tissues.
