All scars are the result of a complex and dynamic wound healing process that passes through several distinct stages: hemostasis, inflammatory, proliferative, and maturation (or remodeling). The way our scar looks after the wound heals depends on a number of genetic and environmental factors. Some smaller wounds will heal nicely and leave only a small white scar that is barely noticeable. Other, more serious wounds, can lead to excessive scarring known as keloids or hypertrophic scars. Atrophic scars, which result from severe acne, may be visible for a lifetime without proper treatment. While most scars are permanent, there are ways to help them fade over time.
