Every time the skin suffers an injury, it runs the risk of healing with a scar. Scars can vary wildly in appearance, ranging from light, silvery-coloured lines on the skin to prominent, raised keloid scarring. Most of us have scars, but for some of us, it can be more of an issue than for others. Those who have scars they wish to conceal may find that they suffer with their self-esteem, and are restricted in their clothing options in order to hide unsightly areas of scarring. On occasion, scarring is not simply a cosmetic concern, and may be uncomfortable, itchy, or constrictive to movement, driving patients to seek to remove them.
