What causes scarring?

The wound-repair process starts with inflammation, moves on to tissue formation and ends with altering specific factors in the anatomy of skin cells – such as the production of collagen, the integral protein present in connective tissue that provides support to the skin, bones, cartilage and blood vessels. Scarring appears when the wound-repair process is disturbed by certain factors such as the production of too much or too little collagen. For instance, a keloid scar is caused by an excess of collagen. Cosmetic lasers form a large part of aesthetic medicine. Laser skin treatments are used to remove excess hair, reduce skin scars, tackle wrinkles, tighten skin, and eliminate warts. With skin laser technology, scars can be made significantly less prominent and may possibly disappear entirely, depending on how persistent they are. In this treatment, a high powered laser is used by dermatologists to remove the epidermis of skin that has been scarred. The laser also penetrates to the skin’s central layers, tightening and smoothing the skin.
