They can be treated by conservative treatment, non invasive, which improves colour and texture, or by means of surgical treatment, applying resection or eventually polishing techniques. To adapt the treatment many parameters must be taken into account, eg. Evolution time, direction of the scar, location, what caused it, extension area and characteristics: hypertrophy, queloide, sunken, broadened, etc. Stretch marks are also scars which can have different improvement treatment.
